Having problems with your 1994 GMC Suburban ?
Turns over but won't start
\015 1994 gmc 6.5 lt diesel suburban 2500 check and replaced all fuses and relays .Fuel pumps has Ben replaced but' no fuel to the injector pump.I know it must be some electrical.what els is the problem.Need a clue.\015
I'll tell ya what a diesel mechanic told me..."fuel injector pump". It seems that the new low sulfur diesel being sold now wears the seals out on the older pumps. I changed the fuel sending unit and that seemed to help a little, but now while driving it will shut down, and it's hard to start. Going to have the job done now. Part is very expensive! Hope this helps.
