Sorry I no nothing about this truck I just got it 3 weeks ago but I do no there is no pmd relocate and when driving I give it gas and the check engine light comes on let off of the gas then it will go off it has a switch in it for a fuel pump that will run consent till you turn it off. + I had the cat taken off as well as the muffler. And how can I tell what gears are in it cuz it's really slow. That's all I no thank you guys

 

Go to autozone and have them checked the stored code from the service engine soon light and they can give u the code then tell us what the code number they give u is..its free.

 

Okay,do you have any idea on the transmisson/wouldn't shift into OD??????

 

Low tranny fluid,torque converter,shift solenoid,ecu? overdrive unit

 

Ok I got the the codes it was dtc 44 and 45

 

Is the 8th digit a S or an F on the vin number on your truck?? if it is a S you are having EGR issues you may need to pull the upper part of the intake apart and do some cleaning as these places build up junk and will throw them codes and cause poor performance

 

Those are EGR CODES

 

Will that cause the truck to stall out at an idle?

 

mine wouldn't start friday , so ended up calling the mech to pick-up.So I didn't get to check anything....Opened the t-handle drain/flowed slowly....still wouldn't start.

 

No LP operation while the engine is running combined with a pin hole in the fuel line between the fuel level in the tank and the LP will cause a stall.

The oil pressure switch powers the lift pump when the engine runs and is a common failure point-replace with AC Delco ONLY!
Also google"OPS relay mod" as well as repair the fuel line air leak-often caused by a rotten sending unit on top of the tank.

Also replace the fuel return line at the frt of the IP with a piece of clear diesel rated fuel line-it is very useful to monitor the fuel flow for bubbles-bubbles indicate air intrusion and these IP's don't tolerate that very well.
