Engine starts then stalls on the road

Have you checked fuel pump pressure? Did the fuel gauge stop working when this started happening? As far as the air bag, you need to have the computer scanned to identify trouble codes. That way you will know what is causing the light to come on.

THis guide can help

Let me know about the fuel pressure. Better yet, see if the engine will start for a few seconds using starting fluid. That will tell me alot.

I have checked the fuel pump and it does have pressure (50)

WIll the engine start if you use starting fluid?

Thanks I had to get a crankshaft angle sensor it fix my problem found out using the great guide. Cost $89.00

Car keeps cutting off and service engine light is on

you have to find out what code is in the computer, then I can be better able to help you out. Could be just a sensor issue. Let me know.

I have a 2004 malibu new body 3.5l, it starts then stalls, I have replaced the fuel pump, ect sensor, cleaned the injectors, checked the injectors 12.4 ohms all the across. no security lights on. but if I press on the gas it stays running. I dont understand it. when the car is cold it starts right up most of the times. any info is greatly appreciated.

If it continues to run if you keep your foot on the throttle, have the idle air control valve (IAC) checked. Its job is to maintain idle when the throttle plate is closed. By placing your foot in the throttle, you are keeping the throttle plate slightly open allowing it to continue to run.

I have a 04 Malibu 3.5 and I replaced the intake manifold gaskets. Engine will not idle. Starts then stalls. If I hold throttle down it will run but misfires. Could this be the MAF. I looked for vacuum leaks and ignition wires are correct.

Hello,

Is there a chance you got some dirt or other such materials down into the intake ports? It sounds like an intake valve is stuck open. Lets try a compression check to confirm.

There was still a very tiny piece of old gasket on the upper plenum that I missed causing a vacuum leak.

Yep that will do it. Nice work, we are here to help, please use 2CarPros anytime.

car was running good with no trouble out of the blue it quits and won,t start, tried spraying starting fluid in thottle body and it runs for a few secounds, sounded like a fuel pump or filter problem, changed both and it still does the same thing , have great pressure at fuel rails, don,t no what else to change to help it, there was no codes found on obd 2 sensor check, can you tell me what else to check thanks Tom

is the security light blinking when your are trying to start it.

yes, the theft security lite is blinking when trying to start, thanks Hope you can help this car has no keyless entry, the onlt security that maybe on it is the key switch that locks stering, there is automatic door locks on it, but no other securiy on it but in the stering wheel key switch

sounds like you need a pass lock sensor. you can try this. turn the key off for 10 secs. crank the key once and let it go. watch for the light to blink. let it sit with the key on, watching the security light. it should go out in 10-30 min. when it does turn the key off for 10 secs then try to start. If this doesnty work you will have to have it scanned at your local dealer.

Hi, tried what you said about leaving the key switch on till the security light quits flasing, this fixed the car, it work was I surprised, your the man in my book thanks so much for your help, Tom

my malibu classic stalls and sputters and then will go again for a car length or 30 miles and do it again . it seems to do it when cruise control is on at 70 mph . i have changed the fuel filter twice.

Has the check engine light ever come on? If it only happens when you are using the cruise control, it may be a bad vehicle speed sensor (VSS).

Does the car ever act funny when shifting?

Let me know.

My car lost power then got back a boost of power then shut off. It still starts and all the gauges go up but after a few seconds it shuts back off again. I've been driving alot today (almost 3 hours straight) and it's around 88 degrees where I live. I checked oil about 30 mins after the car shut down and it looked a little low so I put some in and it will turn over but after a few seconds just shuts back off. I have work tomorrow so I want to try and figure out what's wrong with it as fast as possible so I don't miss to many days of work.

Did the check engine light come on? Have you checked fuel pump pressure? Have you checked if the plugs are getting spark?

No check engine light, the car won't turn over now. Not sure about the fuel pump pressure and I haven't been able to check the spark plugs because I have to unscrew the cover for the engine which I have to get the tool for.

Check those and let me know what you find.
