What type security system? When it fails to start, is the security lite on the dask, on or flashing? One some models, a start and stall, might point to a problem with the security system.

Don't wonder about the fuel pressure, use a gage and check pressure. Some of the national brand autostores used to loan out a fuel pressure gage, if you don't have one. You can call and ask.

The cars security system is factory. Its the Passlock system. My battery is dead I will charge it then try the 10 minute reset to see if that works. We went out of town and car was fine sat for a few hours at a concert came out and car wouldnt start. It does turn over but immediaty dies. I did not know about the reset I did research and will try it. If that doesn, t work any sugestions would be helpfull. Thanks

When I try to start it, it turns over and fires but won't stay started. Like it's not getting fuel, but everything I've checked says it is getting fuel.

Hi,

Have you checked fuel pressure? If it is low, this can happen. Also, prior to this happening, was the check engine light staying on while the engine was running?

Here is a link that explains how to test fuel pressure. If you haven't done this, try it and let me know the results. You will need a fuel pressure gauge, but most parts stores will lend one to you for testing.

https://www.2carpros.com/articles/how-to-check-fuel-system-pressure-and-regulator

Here are the fuel pressure specifications:

Fuel Pressure (Key ON, Engine OFF) .................... 384-425 kPa (50-60 psi)

Also, here is a link that explains the most common causes of a crank no start condition. Take a look through it as well.

Once we confirm fuel pressure is within the manufacturer's specs, then we can move on. However, it sounds like that could be the problem.

Let me know

Joe

Well, I think I failed to mention that this happened after I programmed a new key for the car. So I think it may have something to do with the computer, but I can't figure out how to reset it.

Hey I wanted to thank everyone for there help. I ended up having to keep my battery in charge while I did the programming for the new key. After I did the, leave key on for 10 minutes until the anti theft light goes off then cut key off for 5 seconds three times while my battery had plenty off charge. It started right up. Thanks again for everyone's help.

I have a 2004 malibu classic that won't start. Will turn over and over but not starting, also somthing strange when this occurs, when you move the blinker left or right the flasher buzzes and the lights do not flash. It does this when driving down the road or when it is just sitting, most of the time I seem to be able to move the turn signal switch around till it acs normal then it will start, now I can't get it to work, any ideas.

Electrical problem
2004 Chevy Malibu 4 cyl

the car cranks but does not start, it will momentarily start with starting fluid. It has fuel & pressure at fuel rail. This problem appeared in morning after running fine the night before. The anti-theft light is on but we don't recall it being on before, it has stored no codes, we disconected battery for hours then reconected, still no start.
