Just picked up a 1997 GMC Z71 with a 6.5. New to the world of medium diesels (last was a 2003 Jetta TDI) and still very green on diesel to begin with. Truck has 189k miles and runs alright. Have some odd flutters and intermittnet issues to figure out. Vac line broken from pump, waste gate actuator removed and has a spring with 2 washers to hold open (showing no boost on gauge.) Pickup for boost gauge pressed into rubber hose from turbo to upper manifold. PMD was relocated to a heatsink but is just laid in the inner fender well in the engine bay, not sure of the brand. Thinking this could be the issue...Also has a leak at the filler neck...will be looking for some parts soon to get it right!



Think I did alright for $4k

Supposedly has upgraded injectors and new transmission but nothing to prove when or what. PO said it was done by the owner he purchased from a year ago.

Things to do so far:

Wastegate Acutator
Replace line from Vac pump
Clean VSS
Turbo to intake hose
New filters
Replace/Clean CDR (looks original)
Possible PMD
Flush brake fluid
Replace M/C grommets
Replace/rewire stereo
Tires
Bulbs in dash (no SES light, glowplug light, etc)

Fix the grounds before chasing bulbs.

Poking around yesterday I've found two broken ground straps in the engine bay. Looks like one is just for the underhood light, the other comes off the back side of the right head, just have to figure where it goes. Trying to find diagrams/pictures of the ground locations
 
Welcome to The Truck Stop! :welcome2: Sharp truck. :thumbsup:
That broken ground on the right bank is one of many very important ones.
 
Spent most of today chasing bad grounds...oh joy...haha.

Turns out the broken main strap had been "replaced" on the #6 runner to the frame with an 8 gauge wire. I swapped it out for a 4 gauge and hope that should work a bit better.
 
You should have a wire going from the stud on the engine to the firewall also. I run a ground wire from the battery, directly to that stud. I've seen several cases where the stud lost ground. This way the stud never loses ground. It also doesn't hurt to be liberal with the anti seize
