I have a 99 1500 5.9 ram. Here's my trouble. Last weekend I drove my kid to soccer and truck was fine i parked it saturday and sunday when i went to run it I had a heck of a time getting it started. It cranks over but i have to pump the gas to get it to start and as soon as i take foot off gas it dies immediately.

So monday I did a quick tune up on it. plugs,wires,pcv,air filter, dry gas in tank and started it up it was running like a champ so i took it for a ride about a mile pulled into parkinglot shut it off then tried firing it up and same damn thing. I had to keep foot on gas and brake once i got it started to keep it running and get it home.

So i'm lost on what to try next. i have spark i'm getting gas. i'm thinking a sensor of some sort. tps? any suggestions on what else i could try to narrow this down? Anyone else had this trouble?

Any insight would be great.

 

Try cleaning the IAC(after you remove it, don't push pull or twist it) on the back of the throttle body, clean the bore it installs into also.You'll want to check the fuel pressure with a gauge also.

 

Thanks, I'll give that a try.

 

if its not the IAC then try swapping your ASD relay for the fog light or the horn relay in the PDC (fuse box in the engine).
if it runs fine after that then make sure whatever you swapped it for works.

 

It was the iac!! thanks for help. I cleaned it and truck is running great. thanks again. thats a new one to me. who woulda thunk. lol

 

^ you'll learn alot here trust me...

 

x2. Definitely quite a lot of info here.

 

i woulda thunk

 

Glad it works, just don't expect it last forever. And when you need a new one, don't buy a POS brand from Autozone or the like.
