1995 dodge ram 2500 V-10, stalled at red light would not start up. changed fuel pump, ran good for a while. now it stalls out after about 8-10 miles of driving. thought i got a bad fuel pump, not the problem. finally code 43 came up. change #1 coil, still stalling. also change the egr sensor.

what else could it be? Ive had it at a small local shop but they still cant find the problem so i thought i would turn to the folks that know Dodge's!!

 

I had this problem and I had really bad idle RPMs. I put some seafoam through my engine and I got a new battery and I was golden.

 

bad gas cap?


I'm not familiar with the v10.. but with anything it's the same process of eliminating simple to more complex..

I'm assuming it runs good for 8-10 miles, and gets worse the closer to stalling... does it do this whether it's cold or at operating temperature? Does it fire right back up and carry you another 8-10? It could be that the engine is closing loop and something goes haywire.. It could be a bunch of things.. the simplest one is the gas cap to start with.. if it can't create pressure, then it's a problem.

if that isn't it, you're going to hafta determine if it's fire or fuel.. and go from there.. just follow the processes needed to run that thing from the start to the problem using each of the four big parts- Fuel, Fire, Air, Exhaust.. I'm guessing you can eliminate Air and Exhaust..

 

Ya I agree may be EVAP code or charcoal canister problem.. something starting after fuel pump till the exhaust. Check all in betweens.
