1990 1500 6.2l Diesel stalls while driving.

Welcome to the forum!

You smell diesel - same as a gas engine: something is leaking. You fixed a leaky pipe that I can only assume was a hose. I suggest you continue replacing all the fuel hoses due to age. Checking for a leak should include the injector return lines as these will drip on a manifold and cause a strong diesel smell. Injector lines also can leak. Check the IP for leaks dripping into the engine valley. (Front seal, advance piston on the bottom side, turn up the screw side triangle gasket, top cover, and hoses incl return hoses off the IP.) The filter housing is known to have weak areas that can leak.

IMO your 1/4 feed line to the center of the IP may be leaking due to how much fun it isn't to get to.

X2 on who cares about a code. Seriously all the computer does is run the EGR and EPR. IMO the EPR closes during cold weather to heat the intake manifold and this is the only benefit to you. EGR is not a benefit to you. I would plug the EGR line and be done with it. After all many 6.2's run without EGR and EPR. The rest of your engine is mechanical and runs without a computer. Think 1970's or older gas engines here. You may need to pull the EGR valve and clean it - likely the last owner plugged the EGR line already...

OK but I wouldn't worry about the code too much. Get rid of the EGR. Find a J code intake.

The computer in that truck is for trans control and emissions, hence the EGR code. Another bright idea created thanks to the EPA.

It had control over the auto trans(if so equipped) and the emissions crap, but had no power over how the engine ran.
 
EGR will plug

ok will plug the system, found corroded grounds on block and body by fuel tank.... the 2 grounds to the body from the back of the block were really bad also(pain the !@#$ how ever thought of putting the ground under the heater core hoses .

Cleaned up really well......tomorrow will see if the thing does not cut out on me again......still need to find out where the strong smell of diesel is coming from?

Will have to pull the manifold so i can inspect the ip and fuel hoses for leaks.


thanks for all the help everyone, i think iam close to the finish line(I hope!).

:rof:
 
Success

Success, finally got the thing to run with out cutting out....new inspection sticker.


Thank you to everybody who helped....cool forum........
