The fuel pump is in line, replace it, it's cheap.. If it's still not getting power, then you gotta start tracing the wiring and looking for the electrical short.. Check the fuses too.. When it doubt, think cheapest first..

Did you check the fuel filter? It can be cleaned out manually. I just hold it to my mouth and blow but make sure the gunk-side is away from you.

I have the same problem and have trouble codes 35 and 36. I found out that there is a computer module that needs replaced as it sits low in a valley and gets hot and seperates. I am reseaching about the a/m fix that installs the new module away from heat.

Try cleaning the throttle body and may be taking out the idle air control and cleaning that.With the time of fuel were forced to use nowadays gives us a lot of carbon build up.Have you also tried Cycling the ignition on and off a few times to see if that starts it faster.If thats the case theres still an issue with fuel..But clean all that other stuff first and see what you get..

1994 chevy 3500 6.9 diesel you drive it acs like running out of fuel half to bleed lines to get air out to start back up


sounds like u got a clogged fuel filter, or you have got a fuel line somewhere that is sucking air in, could be anywhere from the pump back to the tank, if that shows no luck, get a piece of clear hose and put that just before the pump and look for bubbles, the slightest of bubbles will cause it do run rough and stall
failing this and there is no air bubbles i would say your injector pump needs rebuilding but this is rather unlikely unless u have got a fair few miles on it


hope this helps

Where is the fuel filter located and how do i change it on a 1997 gmc siera 3500 diesel


Not real familiar with this model of truck...but I'd find your injector lines that take you to the fuel pump. (fuel pump should be driven by a belt)
Then from the fuel pump, I'd follow the fuel line on back to the fuel filter.
Should be a rather large cannister mounted near the firewall.

Hope this is helpful...

Engine replacement


any of the non computerized aka 12 valve cummins will interchange going from the p7100 pump on the 94 to the ve injection pump on the 92 may mean rerouting some of the fuel lines to hook it up. make sure you use all the sensors from the 94 engine though so all your gauges read correctly other than the fuel system the engines are identical though so should have no issues doing this

Turns over but won't start


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.

You are on the right track. 99% sure it is a fuel supply problem. I suspect the lift pump is a likly candiddate or an obstruction inside of the fuel tank. Chack also on the vacuum side of the pump for any loose hoses that could result in an air leak so the lift pump will draw air instsead of fuel

Nope.. It's probably your pump mounted injection module (or injection pump) what ever you wanna call it.. A little control box up in the engine compartment next to the intake.. little 4 wire connection.. Pain in the **** expensive..
