I have a 99 5.2 4wd Duranged that will not start. Was on the home from work when it died. It will turn over fine. I have checked fuel pressure and its good. Had a crack in the coil, replaced it, still wont start. I replaced the pick-up coil, dist cap and button, no luck. No check eng light on. I did get it started for a brief minute but rough idleing and quit again. I am in dire need to get this thing running. I have a 3 year old daughter I have to pick up on friday for the Christmas holiday's and nothing else is important so PLEASE HELP!!!!!!

 

Have you checked your battery? Sometimes a bad battery will cause your symptoms.

 

Battery is good, 13.1 vvolts

 

can you pull the CEL code and let us know what it is? that will help us in the right direction,

 

CEL not coming on but will plug in and check.

 

From a starting poing

Do you have spark?
Check local autozones/advanced auto/oriley/napa etc for a gap tester. Easiest way to check without having to do any wrenching(Cheap/inexpensive)

Fuel getting into the cylinders?
Pull plug to check

 

Checked spark, was good. I have been going thru process of elimination on this and is probably going to end up as something very elemetary, just hoping someone here has experienced this to save wasted time. next stop crank pos sensor, noid light for injectors, last is paying someone to bring a good diagnostic computer out. Lets hope I dont get that far.

 

Did it die when your were slowing down or stopped? Check your Idle air control valve. $36 at autozone. On the back of the throttle body. Held by two torx 25 screws. This is what i'm dealing with now.

 

Check the TPS voltage from the middle wire to ground. Show the results as it should be under 5 volts DC.

Second, is it sparking on TDC?

 

2x mark, definitely check idle control valve
