why wont my engine start

Hello,

It sounds like the security system is engaged thinking the car is being stolen. Please lift the hood and close all doors. Then remove the battery negative cable and hold it to the positive cable for 5 minutes this will discharge the system capacitors and cause a hard reboot. Reconnect the battery and then lock and unlock the door with the remote.

This guide can help

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken

it will try to start but the engine will not over. it just had the full pump replaced and it does have a spark when you start it. But the engine will not come on. Does anyone have any suggestion?

try resetting security system. See picture.

My engine light was flashing but when Auto Zone checked it they said I didn't have a problem. I thought is had bad gas put in it so I started putting premium gas in it.

The engine light went off for a while but it would still run with a slight miss every now and then. Today when I went out to my car it would not start at all. The lights would come on but the engine would not make a sound.

Hi:
Does the engine crank and not start, or does nothing happen when you turn the key?

my aztek will turn over but wont start, i can here the fuel pump turning on, changed the plugs and wires, changed the fuel filter it droped down to 40 then stalded on my wife while driving, now it wont start?

Do you have spark and injection pulse? any fault codes?

2003 Pontiac Aztek won't start. Started fine this morning and at lunch. Came out after work and it will not start. New battery and new fuel pump over the summer. Could it be the gasline is frozen?

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 have a 2003 Pontiac Aztek and the last 2 summers I have problems starting the car when the engine is hot or at least that's what I think it is.It does not happen all the time(it is very intermitent).It is only in the warm weather that it happens.It never happens in the winter.The car does not start after the car has been driven for awhile. 95% of the time it happens after filling up with gasoline.The engine cranks but wount turn over. You wait a couple of minutes and try again. It will usually start within 10 minutes of trying to start it.

Hi:
Have you had the computer scanned for trouble codes? I would start there. Stop at a nationally recognized parts store to have it scanned. Most stores will do it for free.

Let me know if they find anything and we'll go from there.

key wouldnt come out of ignition so i turned it on and of real fast a bunch of times started it up shut it of and turned key on and of a bunch of times again and then went to start it and now it wont start turns over but wont start the fuel pump is not turning on checked the fuse and checked to see if it was getting power to fuel pump and it was getting power to fuel pump. i did figure out how to get key out

This action may have damaged the ignition switch it self, remove the steering column trim and check power through the switch in all positions, start here.

and if it isnt that could it be the fuel pump went or not

because the motor will turn over but wont start you cant here the fuel pump running it will start with starting fluid but wont stay running

car was running fine last night. no problems. went out to start it awhile ago and all it will do is crank. I tried starting fluid. it fired but not well and still wont run. any ideas?

Hi:
If it kicked with starting fluid, it sounds like there is a problem getting fuel. Check the fuel pump pressure. Let me know what you find.

Joe

wont start will turn over but wont start you cant here the fuel pump running it will start with starting fluid but wont stay running i checked the fuses and checked to see if their was power going to the fuel pump and their is power going to it

if power is going to it, then the pump has failed

I ask my mechanic to weild the battery site.but before that the batery have been remove.before weildding the sit.after the car won't start.it writes security on the cluster.

If the security light is on, the vehicle is shut down by the system. There are many things that can cause it. As a result, I recommend taking it to a dealer. They are the only ones that have the proper test equipment to check it.

waiting on answer about aztec not starting

ok doesnt' turnover or doesn't run?

turns over doesnt run fuel pump isnt running it will start on starting fluid and then shut off

then scan for codes and check fuelpressure. fp relay is in underhood fuse box fule pressure shold be 52-59 psi gauge for fp available for rent at most auto parts stores.

Why won't the car start? The lights are not coming on automatically like they are suppose to. I changed all the sensors because the car is not receiving fire somewhere for the car to start.

What sensors have been replaced? Are you getting power to the coil? Is the security light staying on or flashing when you try to start it?
