Ok this this is in refernce to the problem after i changed the plugs.Some of you probably remmember. I got the NEW ECM, Coil Pack , Ignition modual and the car wont start. It cranks like a champ but i wont start.
My father probably wants me to sell the car unless its fixed fast.
Hell even if you want to call me to help me out i would opreciate it deeply.

So if someone could help as best as you possibly could so i dont lose my GN.

If it has no spark at the plugs but, has injector pulses, it is often the module

If it has spark, but does not have injector pulses, It is probably the cam sensor or ECM.

If it has no spark or injector pulses, It is probably the crank sensor or the module.

Go down to the parts store and buy a noid lite for about $8.00. You pull a connector off an injector and plug the noid light into the fuel injector harness connector you pulled off. If it blinks when you crank the car, then you know you have injector pulses.

Anyone listed above can help but they are far from you. You are near Philly. Try and reach Dennis Kirban. He has a great mechanic that works with him. We can help you here too. Did you check all the grounds behind the block. When Jim D'Alessandro did your trans a few weeks ago he may have broke or twisted smome of the wires. Jim Testa has a no start procedure posted around here.
Try and do a search for it. Does your check engine light come on with the ignition on?

If you are near Philly you want to call Dave Heintz at Warminster Auto in (where else) Warminster, PA...215-918-2525 after 10:00am.
He is the best and will set you straight in no
time.
He is also the mechanic for Kirban's and goes over all Kirban's cars.

Dave is the guy I mentioned as posted above. Good Mechanic. Also this is the chart That Jim Testa posted awhile ago. Good info to save:

"OK, to diagnose ANY car, you need to find what you have and dont have. The way *I* usually go about it (which might not be right to some people, but its methodical and consistant so I stick to it.

1) Note the check engine light (if EFI). If its not on, STOP and find out why. Listen to how it cranks. I can pick out compression problems doing this. If you are in tune to your car, you can too. Listen to the starter as each cyl comes up on compression stoke. You'll hear the starter slow down a little at that point. You bight hear deerdeerdeerdeer, where a dead cyl m ight sound like deerdeeeeedeerdeer (great sound effects huh?)

2)Depending how accessible the intake is, I'll shoot 3 or 4 seconds of carb cleaner into the plenum. Either thru the throttle body, or the brake booster vacuum port. If its a lack of fuel problem, the car may start, it may simply kick. If it does either, its time to look to fuel system (usually, although enrighening can bring out a low sec output problem too, so dont take my suggestion of fuel as law)

3) If the car kicked, I'll put a FP gauge on it. If fuel pressure isnt in spec, now you need to see why. Fuel pump, filter, resticted line, bad reg, low batt voltage, bad relay, blown fuse etc. If FP is in spec, its time to hook up a noid light and verify our injectors are getting pulsed. If youre not getting a pulse you will want to hook up a scanner and look for RPM during crank. If you are getting RPM signal, check for spark. If you're getting spark and no fuel, although there is a commanded PW (see below) you probably have a bad ECM. How fast it cranks isnt as important as the fact you get a RPM signal. Next you'll look at Coolant temp to see if it coincides with ambient )if the car is cold), and verify TPS isnt shorted to Vref which will put the car in clear flood and cut off fuel. If these all look OK, you'll want to take a look at commanded PW.

3) If the car didnt kick, I'll yank a plug wire and see if I got spark. If I got no spark, then I'll check also for inj pulse using a noid light. If I have neither its usually due to a dead crank sensor. If I have no spark, but I have injector pulse, its usually a module.
Typically:
No start - no spark, has inj pulse -> Module
No start - has spark no inj pulse -> ECM / cam sensor prob
No start - no spark OR inj pulse - crank sensor or module

Oh, and if the module is dead, I suggest putting a coil pack on it as well as most of the module failure are caused by an overheating or arcing coil."

OK, call off the dogs. *G* I just talked to Greg Sr., and they found the problem. Some spark plug wires were bad. They are getting some magnacores to replace them.

(*G*=grin) :p

Way to go Tim! I actually thought it could have been the spark plug wires, I had the same problem last year.

Glad to hear it worked out! powersix

Oh yeah, the poor guys got a bad chip to boot! They unknowingly put a defective chip in then continued trying to get the car to start. :(

Another good reason to cobble together a selection of known good parts to swap in. Sometimes the 'try me' method is the way to go.
