My car is a 2001 chevy lumina with 183k miles on it. Used to be an old mail car, but runs great. Never had any problems with it until I left for basic training and ait. My dad said he started it occasionally but the day I came back I attempted to start it and it would not start. It will run off starter no problem but as soon as the squirt is up it will quit. I can hear the fuel pump priming up, we put some fresh gas in it also but still no luck. We checked the fuses for the injectors and they were fine. Also put my fingernail in the fuel pressure check spot on top of the motor and fuel sprayed out. I was told maybe mice may have gotten in there and chewed a wire somewhere, which really wouldn't surprise me. But then a mechanic told me something about an alarm system, but my car doesn't have one but then he responded the computer has one. Not too sure on what to do.

First, there should be a security light that comes on when you turn the key to the run position before starting. If it stays on when you turn the key to the start position, if it flashes or stays on solid, the security system is stoping the car from starting. The bad part about that is a dealer is the only place that will have the proper test equipment for that type of problem.

One good thing I can tell you is this. If the security system is stopping the engine from starting, you shouldn't have spark or fuel to the engine. Since it starts with starting fluid, my guess is there is a problem with the injectors or the fuel pump isn't producing enough pressure.

THerefore, I need you to check two things. First, I need to know if you are getting enough pressure to the fuel rail. Here is a how to for checking:

Next, if the pressure is good, we need to check for an injector pulse at each injector. Basically, it is a small test light that is used to detect power to the injector itself.

Overall, you will need a fuel pressure gauge and a noid light to complete these test. Most nationally recognized parts stores will lend or rent the tools needed. Go through the tests and let me know what you find.
