Car died and will not start

I have a 2000 GTP. Yesterday I got in in to go to work and it started right up. I forgot something so i shut it off and ran inside. Came back out and again started right up. Put it in reverse and began to back down the driveway got about 5 feet and it died and now it will not start. I can hear the fuel pump working but it just wont turn over. It will crank but wont fire. Does anyone have any suggestions?
 


You need to verify if you have spark and fuel at the rail, and what the fuel pressure is. ICM, crank position sensor, fuel pump resistor come to mind.
 
I know that the fuel pump is operating. I was going to try the fuel filter as it is cheap and easy. How do I check for spark and fuel pressure? Thanks
 
I just checked for fuel to the rail. I attempted to start it so I could get pressure and depressed the schrader valve on the fuel rail and i definitely am getting fuel to the rail with pressure. I am at a loss here. I am thinking it must be something to do with a lack of spark.
 
Pull one spark plug wire off at the coil. Crank..do you see a spark jumping around?

Could also be a maf sensor or TPS. If either went pissy on you..they could keep it from starting.

Bill, if the MAF goes to crap does the car not try to run off the preset tables in the ECM, or since it is still plugged in it doesn't try this? Basically stating that the only way to get it to run off those tables is to completely disconnect the MAF?

Someone suggested I try starting the car with the MAF sensor disconnected. I tried and still nothing. Since I have good starting power and I have fuel pressure to the rail I am assuming at this point that it is either a sensor or a spark issue. I just dont know where to go from here as I am tight in cash to be putting into the car.
 
Pull a wire off a coil and check to see if you see a spark jumpin around when you crank it. I say coils because you can see them from the driverseat

FM - it doesn't always work that way. When the pcm sees it as failed, yes it'll revert to the VE tables. I've had a case where I had a bad MAF on a Gen V swap situation and the car wouldn't start. Unplugged the maf and she started right up. I was scanning and did see some air, but the values were so low the pcm didn't give it any fuel. Although it would start and stall back out. I'm assuming in this case that the OP's car doesn't start at all, but can't be 100% sure since we aren't there.
 
I am leaning towards it either being a coil or a crankshaft position sensor. I havent ahd time yet to check for spark. thats gonna be my project for this weekend. Any more ideas tips or inputs will be highly appreciated. Thanks guys
