I'm out of ideas. I replaced the dristributor recently (along with cap, rotor & wires) which involved pulling the intake. All went back together and started 1/2 a turn as the truck has always started for the 10 years I've owned it. Drove it, started several times that day with no trouble at all. I was satisifed that the timing should be very close to where I pulled the old distr. First really cold morning, just cranks without even trying to start...wtf? Checked the 1 year old coil and seems it had to low of resistance while cold so I warmed it up in the shop and tried again a few hours later...no luck, no codes, no blown fuses, ASD relay is okay, battery is fine, fuel pressure seems okay, everything seems connected okay. This one has got me stumped so far. Going to change the coil anyway but I'm doubtful it will help. It's like something just shut off everything which is why I checked the ASD...any thoughts would be appreciated!
