I have a 1996 6.5 diesel suburban, I got close to another 100k so bought the works to upgrade!
Pressure washed engine & couldn’t get it to start, waited a week then it started… ran fine for 20min then wouldn’t go over 2 or 3 RPM!
Waited another week & it ran like a champ… then went back to the same problem a week later!
I hadn’t done any work on it yet so I started discovered gas line had a slit in it so I went to summit & bought gel lines & replaced all of them (where hoses is).
Before putting intake on I started the truck to make sure IP lines where not leaking.
Put it back together now dam thing won’t start??? I’ve bleed the lines checked the flow to injectors still nothing!
I was old that the PMD was the source of my problem from the start so got a aftermarket PDM & moved it!
Still no start!!! SOS I need help this is my money maker & I aint making any… just spending right now Signed broke as Hell!

 

did you check lift pump, ops, air filter, fuel filter.
see if any thing is full with water ince you power washed it.
