Engine wont start

The security system has it shut down. The only place that will have the proper equipment to identify the problem is a dealer.

Try this, turn the key on (run position) and let it set for 10+ minutes. It should bypass the system so it will start.

Let me know if this helps.

98 buick lesbre ran out of fuel added 10 and it wont start. checked fule rail release valve twice ,pump is working & has fuel to rail,has arc at coil what am i missing?

Check the fuel pressure if its within specs and also if the injectors are pulsing

security light will come on and lockout the car. will then timeout and start.
used to happen once a month but more often now .could the key be bad?
or can the security feature be bypassed? the key could be as old as the
as I bought used about a year ago.

try resetting it first. see pic

This system uses Passkey II system, not Passlock so there is no relearn procedure. Your key should have a visible pellet in it. You can measure the pellet resistance and install a resister of the same value between the 2 wires connected to the sensor in the ignition lock. This would bypass the sensor portion only and the rest of the system would have to be operational. The keys rarely fail.

Engine would not start. Checked battery and it was ok. Bumped starter several times and it finally started turning the engine over, but engine will not fire. What should I look for?

check for spark, fuel pressure and injector pulse. let me know what you find

Local mechanic says he pulled plugs and one cylinder had water in it.He says head gasket is blown and the gasket will cost around $300.00 for a good one. I had checked the oil before I took it into the shop and it did not have water in it. He says it will cost $750.00 to repair. Doesn't sound right to me. Is he trying to rip me off?

he is more right than the 300 dollar guy. that seems really cheap to me

Sorry I wasn't clear, he is the same guy. He said the gasket itself would cost $300.00. Labor and all would be around $750.00.Are gaskets really that high?

call around and see,

The car will start up when the engine is cold, but after it has warmed up and I shut the car off, and then try to start it up 15 mins. later or longer, then the car will not start unless I hold my foot on the gas to keep it idling until it will idle on its own, sometimes taking a minute or longer. What would cause this? I have changed out the computer and the maf sensor already.

possible IAC valve problem? any CEL to read codes?

when you keep it running is it rough or smooth?

When I keep it running, it runs smooth.

IAC valve controls idle via ECM reading sensor inputs most notably ECT.

I had replaced the starter and altenator on the lmy wife car I found that the tip of the starter was broken off in side the fly wheel area. After replacing both the altenator and starter the car still wont start. I tried to charge battery and it still wont turn over. I charged the battery for an two hours and still not turning over. When I try to start it its as if something draining all the power. I hear a click noise when I turn keys to start. As if the starter and Altenator are trying to turn over but end up not. I did this twice now All I get is clicking sound. I was wondering could this be my fly wheel or some other electrical problem?

Where is the click coming from, the starter?

Its hard to tell because the alternator is turning to turn and it sounds as if the starter is trying as well.

1998 buick lesabre will occasionally not start

Next time it refuses to start don't wait for it to make up its mind-do below immediately to determine if its fuel or spark problem

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if so, 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, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing

i think its in the sycurity system. have had the problem before. its my moms an she had to unlock passanger then driver side door to make it start..is the problem in the steering coulum..and is it hard to fix?

Hello i don"t think the problem is in the steering column from what you are saying the problem is in the security system itself. First thing is to see if its a factory alarm or after market and check the remote to see if the battery is dead in it and if not start checking for any ground wires that are not making a good connection that may be causing the alarm to work properly. Hope this will put you on the right track

I place neg battery cable to starter and used more jumping cable to jump start. The engine behave like I had a weak battery.

Make sure the battery has a full charge. Battery connections all good. Then check your charging system. Don't use the alternator to charge a dead battery. Just my opinion.

replaced crank sensor and still have no power to plugs and injectors.

try a different key then scan for codes it may be a security issue so check that with scanner.

While I was changing my oil the other day, I had my car radio running. Right around the time I finished putting the new oil filter in, the radio turned itself off. I tried starting the car and it wouldn't start, just clicked sporadically. My power windows and locks were sluggish. I had the battery tested and it was 60% full, so that wasn't the issue. Any idea what could've happened?

The 60% battery is the problem. At that level it is too weak to start you car. also, check for corrosion at the battery terminals (especially the positive cable), make sure they are clean and tight (making good contact).
If you have corrosion, and the 60% battery power, that's enough to keep it from cranking.

60 percent??? It's dead. I don't know of any tester that measures in percentages but you need to recharge the battery at a slow rate for an hour.

The best way you can test the battery yourself is with an inexpensive digital voltmeter. A fully-charged battery will measure 12.6 volts. A good but discharged battery will measure close to 12.2 volts. At 11 volts or less a cell is shorted and the battery must be replaced. That only tells you the state of charge, not how long it can deliver current before it goes dead. That amount of time decreases as the battery ages due to the lead flaking off the plates.

I have a 1998 Buick LeSabre. It started running rough. Felt as though it had jumped time. Pulled over and had car towed home. I have checked battery, it was good. When I turn switch over, I get no reaction from starter, so engine will not start.

use a socket to see if the engine will turn over by hand. If not, remove the spark plugs and see if it is hydrolocked on coolant. This engine has a known problem with the plastic intake manifold deteriorating and leaking coolant into the vacuum chamber under it.

I was driving the car and it kinda bogged down till it cut off. The car wanted to start but it wouldn't. I thought it was a fuel problem so I put a fuel pump in it. After installing it still wouldn't start. I realized soon after there was no anti freeze in it. So I pulled the spark plugs out of it and they were covered in anti freeze. I pulled the upper intake off (the plastic one) and their lied some anti freeze. Car never ran hot. While putting the fuel pump in, the rear of the car was 3-4 feet in the air while the front was on the ground. Is it possible that gravity took its tole or theres another issue.

pressure check coolant system for intake/head gasket leak.

this car afer driving a while, will not start again until car sits a while

Usually an ignition module. They will run OK until hot, then will run again when cool, then fail when hot.

They can be tested at most autoparts stores for free.
