Engine wont start

Is the security light on solid or flashing with the key in the run position?

Here is a guided to help us get started. It sounds like the fuel pump has gone out.

Please run down this guide and report back.

flashing

Okay lets reset the alarm system by following this guide.

Please run down this guide and report back.

thanks for your help I will give my brother all this information tomorrow and let you know how this works out. goodnight.

Yes, contact me through this question.

My brother looked at it using your guides and figure out the fuel pump has bad, The security reset but it still didn't run. FYI

Glad you could get it fixed, that kind of problem can be tough. Please use 2CarPros anytime we are here to help.

we replaced the starter, and now the car wont start do you have any suggestions as to what it might be.
my daughter drove it home shut it off we went out to change the oil and it wouldnt start, so than we realized the starter was bad so we replaced it now the car turns over but will not fire.
the electric fuel pump runs when turning on the ignition.
we are in need of my car, can you please help me

To determine what's causing it if its fuel or spark problem do below and get back with some results

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 in away from ground have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,cap and rotor /distributor pick-up coil, ignition control module, ECM,Ignitor camshaft and crankshaft sensors and computer. Note: If it doesn't apply disregard it

I was driving my car the other day and the light turned red for the tempature. I then started seeing smoke/steam coming from the car. I drove a little more and then it stopped. Someone stopped and helped me push it to the side . I went home and came back to the car. I put several gallons of water into the radiator and it did bring the temperature down. However when I went to start it, it wouldn't turn over and the service engine soon light lights up. Please help.

So when you say it won't turn over, do you mean that when you go to start it nothing happens at all or do you mean the starter turns the engine but it won't start?

when i turn the key, it makes a little sound like it wants to start, but it does not fully go all the way

Ok if the starter is good then it sounds like you may have let it get to hot. Have you pulled the plugs to see if there is any antifreeze or water in the cylinders? My thought is that you may need to rebuild or replace the engine. Let me know about the water in the cylinders and about the starter.

Buick - power windows dont work and seat will not go back but the fuses are good. What could this be? It is not the battery or fuel pump and the check engine light isnt on.

check the fuses and see if you are getting owr to starter. if you are hit the body while trying to start if it starts you need another starter. try resetting your anti theft-turn key on until theft light goes out then turn off then try to start. for the windows check the three things i have pointed out first. then the switches and motors.

I have good battery connection, haven't had any problems. I killed it and it wouldn't start again. The engine wouldn't turn over at all. What could it be?

skin i am haven the same problem. shut the car off one day and went back to start 10mins later nothen. i have pwr but when i turned key over i would get no response out of the car. My problem is the factory secuirty system in the car. the chip in my key (little back chip) is not reading. GM dealer ship says wires are broke or key needs to be remaped to the car. either way prices 200-650 to have it done i am looking for a way to bypass the secuirty system as soon as i find a way i will let you know so you can try
at this time i am going to pull igntion and try to start the car without the key i will repost my findings
if anyone else has this problem and knows how to bypass the secuirty system pls leave a message my buick is 95 v6 3600 or 3800 i cant rember

just got done ripped the stearing coloum apart to get to the ignition the one of the wires had been cut dont know how but went to the security sytem. splyced a new wire to the security sytem and car started took about 4hrs but well worth trying myself save 500-600 in cash i would say check your wires hope you have as much luck as me

i have a buick lesabre 98 it wont start at all and i got to start with starting fluid but when it would stay on and i would put it in reverse or drive it would die out

Do you have a check engine light on? If so, start by scanning the computer. If not, check fuel pressure with engine off, engine on at idle, and engine on in gear and reving high. You may have a clogged fuel filter that feeds the engine enough fuel to start but not run under a load.

Engine Performance problem
1998 Buick Lesabre 6 cyl Front Wheel Drive Automatic

i got in my car and it started then i forgot something in the house so i went inside. came back out and tried to start it but instead of starting the car clicked loudly fastly and the interior lights all started blinking in random order. i changed the starter but the car still does it. any suggestions?

Did you ever check and see if your battery cable's were clean and tight.Also i would have your battery charged and tested sound's like something is going on there.I would say that your alternator failed or your battery just was bad.Start with the battery though.

We got an oil change less than a week ago, then got the brakes done a couple days after that - so my car was in 2 shops last week! When my wife was coming home from the store today, it turned on, but seemed really weak. The car was on, but was a really low hum. When she put it in reverse, it began shaking back and forth. She turned it off, then started it up again, and it seemed to have a little more power, but still not normal. She started to reverse again, and noticed there was some greyish smoke coming out the tailpipe area. She decided to try and make it home, which was only a few miles away.

It seemed to be driving fine, but would shake a bit at low speeds, but not when she was at a full stop.

A few hours later, we go out to try and start it, and it gives one loud click, then nothing. I looked under the hood and realized there is no coolant in the reservoir. I filled it up, and put some in the radiator cap. The car still does the same thing.

I cleaned out the battery terminals. I haven't yet tried to jump it - it was a little late, so I didn't want to ask a friend to come over.

But if it doesn't end up being the battery, what else could it be? Why would there be no coolant?

There should be coolant leaking out or a sign of coolant leak. If not the engine is consuming coolant somehow. These engines have a long history of the lower intake gasket leaking coolant into the engine oil. Coolant in the oil is damaging to the bearings inside the engine.
If the engine is not cranking over first I would make sure the crankshaft spins. Attached a large ratchet to the crankshaft and try to rotate the engine over. If it doesn't spin, remove the serpentine belt and try again if it still doesn't rotated you have a seized engine.
With no coolant/anitfreeze in the engine the heat created by the engine has no where to go except into the metal around the combustion chamber which will overheat the metal causing the metal to warp/distort usually causing the head gaskets to fail allowing coolant to enter the combustion chambers or reducing compression pressure.

I know some people don't speak cars so if you have any questions or a better explanation feel free to ask.

Everything electrical works fine but the motor will not crank. When the key is turned the light on the radio goes out but I do not hear and clicking of the starter. This just started happening. If I try it again later it may start. Is it possible there is a security interlock that is failing?

it is possible the starter motor is jammed .. try tapping it with a hammer or something heavy .. if this doesn't free it then it needs replacing .. but like you say it could be your immoboliser

DESCRIPTION & OPERATION
WARNING:Deactivate air bag system before performing any service operation. See AIR BAG RESTRAINT SYSTEM article. DO NOT apply electrical power to any component on steering column without first deactivating air bag system. Air bag may deploy.

PASS-KEY II(R) SYSTEM
PASS-Key II(R) is designed to prevent vehicle theft by disabling engine unless an ignition key with a specific electrical resistance is used in the ignition key lock cylinder. PASS-Key II(R) system operates using sensing contacts which are located within the ignition key lock cylinder. These contact a key resistor pellet which is located on the ignition key. When the lock is rotated, battery voltage is applied through appropriate fuse to PASS-Key II(R) decoder module. Pellet resistance is then compared with programmed value in module. 15 different resistances are used. System components include ignition key, ignition key lock cylinder, PASS-Key II(R) decoder module, starter enable relay and Powertrain Control Module (PCM).

This car has 50,000 miles, in great shape, nearly new battery. Just recently (sometimes)when I try to start it, nothing! No starter engaging, only a faint "click" from somewhere near the right side of the car. I shift through all the gears, back to park, nothing. Take the key out, reinsert, open and shut doors, locks, back to park - nothing! Sit for 5 minutes and try again. Magically, it starts. When home and in the garage, it won't start again. After going through the pre-described voodoo it starts 10 or 15 times in a row. Household expert (who finally witnessed the curse) says it's not the starter and thinks I may not have had it fully in park. I say "Hogwash!" What do you say?

When the problem occurs, could it be the security system acting up?

I have replace the ignition control module and coil packs as well as the crankshaft positioning sensor and still no spark at the coils. The ignition control module isn't getting any power and the wire that runs power to it has continuity from the fire wall to the module I also found a second ignition tumbler wired up under the dash I am not sure what route to go if I could get some suggestions or some answers it would be greatly appreciated.

Primary voltage to the ignition module is the pink wire. That circuit is fused, our database says voltage comes from fuel pump fuse. Not only check the fuse, check for voltage on the fuse circuit, goes hot with the key on. If that fuse is blown, check your fuel pump.

The ground wire for ignition module is black wire with white tracer, check the ground, also.

All of my fuses are in working order as well as my fuel pump I have pressure at the fuel rail.

I also rewired the ground and I have ground throughout

Like I said, that pink wire is primary voltage to the ignition module, according to our database. If no voltage on that wire, backtrack the circuit.

Just to add, note the diagram. At the fuel pump fuse, goes hot with key on, there are two wires. The one that goes straight down, goes to you ignition module. The problem could be where those two wires join at the fuse box? I hope we are talking about the same wire, you said no power.

I have a 98 lesabre that wont start. It just clicks. I got a brsnd new battery n ive tried tapping on the starter w a hammer. When I jump the solenoid with a screw driver I get plenty of spark and clicks but it will not crank the engine

I found the break in the circuit and have power to the module again but it still won't start it tries to start but won't stay running. I have spark and fuel pressure. Any idea what my problem could be?

The key thing here is the battery "must" still be fully charged!

Most of what i cover will cost you nuthin'!

This'll save me a bunch of pecking!

Return here with good news!

The medic

Battery has a full charge? No security lite flashing on the dash? With good spark--proper fuel pressure spec, then I would check cylinder compression. If all is good, I'd have to check for applicable trouble codes. To check possible codes, yourself, at the least you need an obd2 code reader. I need something to point us in the right direction.

my 98 lesabre wont start with key.if i jump starter ,car runs 5-10 seconds and shuts off.with key on,security light blinks cotinuously.anti-theft relay?location?
