Rent a fuel pressure gauge then the fuel pressure gauge hoses screws onto that threaded nipple that goes up to the injector rail. Then you will turn the key to the run position let it sit there like 5 second's do that a couple of times and see what the reading is. See if they have a injector noid light you can rent also that plugs into the injector harness instead of the injector then you crank the engine and watch for the light to flash not stay on solid. You will check all injector harnesses with it. Let me know what you find.

So I would have to take apart items to get to the throttle boby? Am I able to buy the starter fluid at an auto store?

Yes you would have to remove the intake air tube to spray starting fluid in intake.

This is a diagnostic aid, to isolate fuel problems from ignition.

No sercuirty light is on in my car. When a fuel injection cleaning is being done, will that be one of the procedures to clean out the throttle body/intake? What does PMC stand for?

Fuel injection cleaning is done by removing fuel pump fuse, removing the test port cap at fuel rail and connecting a fuel injection cleaning solution.

Engine is started and runs off the solution until it runs out (4-5 minutes).

You need to isolate the problem, fuel or ignition. Once you know what the problem is, you can then correct it.

If no fuel, for example, it could be fuel pump, filter, injectors, fuel pressure or PCM (Powertrain Control Module), or engine computer.
If engine runs with fuel injection cleaning solution, then problem is fuel related, if not then ignition.

Also, you should disconnect the negative battery cable first, never the positive.

Thanks for the advice, timing and crankshaft sensor ok also. There is no reason we can find why this car will not start. Mechanic and I have researched everything we can think of and still no luck. Any other suggestions are more than welcome, we are at wits end.

No spark and everything on the ignition system checks out-could be a wiring/input signal missing to the PCM or the PCM itself

This morning after the hard freeze, my car wouldnt start. It was cranking fine thr night before. We tried boosting it off and we had the battery charged up. It still wouldn't turn over. So when my son put his battery on it and turned the key a couple of times the car did nothing, then on the 3rd time it turned over, but there was sound like the starter or the flywheel. Then we put my battery back on and the car cranked up. What could have cased the engine not to turn over even though we tried with a boost from a truck.
Thank you,
Curious

Try direct jump start at the starter-if you hear the solenoid clicking and starter not engaging the engine drop the starter

We finally got the car started. And you are right it is the starter going bad. We had to use a battery with more cranking amps to get it started. The selenoid is bad.
Thank you,

I have a 2003 Pontiac Grand Am and I can't get it to start. When I turn the key the lights dim like it would any other time, but there is no reaction from the engine itself. I was told by my father-in-law that it may be the starter, but after replacing this I was still experiencing the same problem. What could this be?

Check the battery and connections if okay -check fuse , crank fuse 10amp and PCM ACC fuse 10amp-if okay Test the park and neutral switch and starter relay-see below:

Sometimes my car cranks right up, at other times it just cranks over but does not start. Sometimes when it doesn't crank, you can turn the key over and it starts, then sometimes this doesn't work. I can start the engine, turn it off and try to start again and then it just cranks but doesn't start, or sometimes it starts up again. No ryhme or reason to why. Seems to crank up right away as long as it has sat for several hours like overnight or while at work. But sometimes after only a couple of hours since last started, it won't start, just cranks. My security light has also been coming on alot lately. I have to sit with the door closed, key in ignition in off position for 15 minutes then it starts, or sometimes just cranks with no starting. The chip is in the ignition and not the key if this helps any. When the security light is on and you try to start, you get no crank or anything. Thought I'd mention in case there is a relation to these 2 things. Another thing that may be related or not is that I have a clicking noise in my dash when I turn on turn signals and doesn't go off after making turn, but I can wiggle the turn signal and windshield wiper knobs and it will stop. Sometimes this thing clicks for no reason too.

Yes, there is nothing wrong mechanically with your vehicle. Your Passlock anti-theft system is to blame for the no-start error. If you read the description of Passlock, you may want to check your ignition tumbler, making sure that it is not loose or not making contact. The are several conditions that the Body Control Module looks at to create a successful start. If one of the condition is not met, the vehicle WILL not start until the BCM resets, which generally takes about 10 minutes. (Try this the next time it happens. I am not sure if it will work with GM vehicles, though. If the SECURITY light turns on, DO NOT crank the vehicle. Exit the vehicle, open and close all doors, trunk and hood. Go to the driver door, and use the KEY, not remote, to lock the driver door. Wait 1 - 2 minutes, and use the key again to unlock the DRIVER door.)

Thanks so much for the very in depth description of how the security system works. I was told that the codes were coming back that it was security system, but had no idea for sure that it was causing this car not to crank sporadically as it was. Thank you Just one more thing: Is the clicking in the dash also the security system?
