I bought 99 ram a several months ago and ive done a full tune up chaged the fuel filter and it still wont run. It will crank but wont fire unless i put my foot in the gass. it also has a new crankshaft sensor and iac any help would be greatly appreciated.

 

Have you checked the throttle position sensor (TPS)? If the computer is not getting a signal from the TPS it the computer will not signal the fuel injectors to deliver fuel.

yank off your throttle body and clean it. there is a small air passage that could be plugged causing a problem. the iac should overcome this, are you sure it's working?

 

its the third one i put got any other ideas

 

i had a problem with mine when it got cold out last year it just died and would not fire up whats so ever so i changed plugs wires rotor cap fuel pump was good it had a check engine light on for no cam shaft sensor replaced that then it worked but would barely run and ran like total crap and would stall so then at a loss i decided to buy some iso heet and see mabe that would work poored it in started and ran like crap for like 5 min then like instantly smoothed out so u could try that and see if mabe that helps gets all the water out

 

still having problems nothing worked

 

explain again what you have done in detail.

 

Had problems with mine doin about the same thing in cold whether . I changed the plugs and wires added a performance coil haven't had any more problems so far

 

What happends when you let off the throttle? my truck was doing the same thing but when i let off the gas and it went ot idle speed it would stall. Turns out that somehow I had blown the alternator fuse in the fuse box under the hood along with several misc fuses. Went the the dodge dealer with one minute to spare before closing on a friday. It was aroung 12.50 with tax I installed it and ran like a champ except had to buy a fuse so i could have a running instrument cluster to drive the three hours home.

 

Explain a little better as too when the problem started... did it not work from the day you bought? it or did this just start happening? These guys are good at helping but the need a little more info. It could be a lot of things.
