Hey I've been dealin with this 02 4.0 that hasn't been ran in in about a year. When parked ran fine. She has no codes, cranks no problem, has spark (checked visually on 1,2,4,5,6) don't want to deal with that 3rd cylinder spark plug right now. Changed spark plugs in 1,2,4,5,6. Has fresh fuel and fuel going to rail. (Do not have a fuel pressure tester currently) but when pulling plugs after cranking, they have fuel on them. Did compression test on 1,2,4,5,6 and all were within 165-180 psi. Spark plugs were not in terrible condition. Old spark plugs were gapped at about .06 with little foul. Originally on first day, when started she fired for about 2 seconds like 4-5 times and then would fall on her face. And then never fired off again. Tried using wd40 as starter fluid still nothing. Been working on it for about two days here and there but feel like I'm stuck. Fuel inertia switch is good too btw. Air duct is free, and air passes through IAC.

If anyone has ideas or anything, they will be much appreciated.
Will buy a fuel pressure tester within next day or two and will post results.
Thank you
 






Thoughts I've had: fuel pressure as stated, injectors gunked, weak spark
