I have not checked the fuel pressure, I checked all the fuses inside the cab & in the power distribution box, I checked & tested all the relays they are all good. (I switched them all 1 at a time with the power window relay & they all worked) I figure it has to be a spark problem because I sprayed it with starter fluid & it did not try to run. It just cranks. The truck was running fine the day before, has 130K miles & this is the first time of any problem. The motor has Coil over plugs, so it doesn't have a distributer, & the CPS is what fires the sequence. I have a manual & it looks like the power to the sensor comes from the PCM (NO power at the plug), but I don't want to spend $250 to try a new PCM. The day this happened it was -5 deg. outside & I can't get it in a garage.
