Cleaned the Mass Air Flow Sensor (didn't look too dirty) and while I was there, I checked power at the sensor and for an open circuit and all checked out fine. I also checked the IAT sensor and it was within spec, 5-volts at the plug and resistance was high as expected in the morning.
The truck started right up and I thought the cleaning was the magic bullet, but no dice. I drove it for about 5 miles and it felt really nice and smooth, no problems - I was sure I had fixed it. Then I shut it off and tried to restart and it will not start - just cranks and cranks. It did shutter a little like it was trying to start but nothing. I decided to give it a squirt of starting spray and it started instantly but died just as quickly, so I am pretty sure I have a fuel issue someplace.
Pump & filter are new as of this weekend. What else controls fuel flow? Faulty relay? (Can they be intermittent like that) Inertia switch? Fuel pressure regulator maybe? I'm stumped.
Rasmataz any more ideas? I would appreciate your thoughts on this because I'm fried!
