I have a 2000 Durango with the 5.9 in it. I just replaced the front bumper and fenders. Pulled it outside and it sat for a couple days. Went to start it to bring back into the garage to continue the body work. It wouldn't start. It has spark to the plugs, and is getting fuel up to at least the pressure valve... I'm lost!!

 

Is the tach moving when you crank it (crank position sensor)? Does it fire if you hold the gas open a bit (weak battery/iac not keeping idle)?

 

no, tach does not move while cranking, nor does it fire with gas open.
