1993 6.2 Diesel ECM
What does this govern? My trucks glow plugs used to flicker when driving before I had them manually overrode from the ECM.
My truck is a 1993 K1500 J CODE Swapped intake(originally C code(egr)), 5 speed manual NV4500, 4X4
When I kill my glow plugs from the ECM my truck idles lower. I also noticed random jumps in power.. and sometimes I notice gutless lagging speed.
Thanks for input

with a 93 the ECM usually only controls the auto trans.
if you havea standard then I have no good ides what the ECM does?
I suspect that you may have a faulty oil pressure switch if the LPdoes not operate when the engine is running.
If you have a prime cycle on the LP circuit then it may have been modded to run with the glow relay?

344 pages of AWESOMENESS! lots of pics and illustrations too..
Although not intended to replace FSM, it is far more accurate and useful than any Haynes, Chilton, or thers worthless 6.5 publications.
Suggest you down load it...

Thanks for your help

If you find the fuel heater defective,, plan to replace it. FWIW a new fuel heater alone cost nearly as much as a new completely preassembled "drop in" fuel filter manager..
