The thing just wont start, turns over like a champ, but won't fire. It has Fuel, spark, air and compression. The cold air injector sprays well. Ran fine one day...parked it at about 1:15 in the morning after driving all day and the drive home was 10 miles, ran fine. Came out the next day to 80 degree weather and it wouldn't start and that was 6 days ago. New plugs, plug wires, distributor cap + rotor, checked all vacuum lines that we could see and they had no leaks. All fuses are good. Tried 2 different ignitors with no luck, swapped EFI and Starter relays back and forth with nothing different. Tested the timing and it is good to go, used a timing light. Battery is kept charged manually. I have a video of the engine trying to start if you want me to try and email it to you...not sure of how well that will go over.

It's a 3.0L v6 automatic, 154,xxx miles. ANY suggestions?

Thanks.

Can you hear the fuel pump come on as your cranking and here the relay in the passenger kick panel click? See if it's the mass air flow meter, take off air cleaner and inside the top cover is a flapper that when pushed in turns on fuel pump, put long screw driver and push back the flapper and turn on the ignition and see if it starts and rule out a bad MAFM.

mine wouldn't start, was told to do what I just told you and wa la truck started right up...

Hey thanks guys...we figured it out.

There was compression...but not enough. Meaning, we had a blown head gasket.
