Question about 1994 Chevrolet Silverado 2500

1 Answer

I have a 1994 Chev half ton with 6.5 turbo diesel, have problems starting, motor turns over, lots of fuel, fuel pump working, has a mind of its own, when it wants to start. Some times a few hours after trying to start it, & its starts,some times not. & in the past when it was running, sometimes it would just shut down, but would start back up, starting problem wouldnt make a difference if motor was hot or cold.

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

My 6.5LTD Silverado will not start


I'm assuming you a talking about a Turbo Diesel. Diesels can be complicated. I would suspect the fuel injection pump. It must reach 1900psi to overcome the compression.

I've had pumps go bad because of the ultra high tolerance needed in the pump itself to get to that performance level.

I was driveing down the road an my truckwhich is a 1999 dodge ram3/4 ton with the cummins turbo in it started spitting an spuddering an then died. the codes from a cheap scan tool showed p0216,p1690 and...


The p1690 is the transfer pump code I believe. Unfortunately the engine will run without a good transfer pump for awhile. Eventually the main injection pump will fail due to lack of fuel pressure. The main injection pump requires 6 psi minimum. When the main pump fails and this is the unfortunate part it's trash. It is possible you just lost enough fuel psi that it died and a 160 dollar lift pump will fix you up. I would suggest a fuel psi gauge on all 98 and a half through 2002 dodge diesels. A 80 dollar gauge can save you about 1800 dollars and that 1800 is if you do it yourself.

1994 chev truck 6.5 turbo diesel with long hard start ,idles good and smooth,rev it up and it craps out and smokes a heavey fuel cloud, unplug optical sensor and engine runs better but still has a stumble...


There is a cold start solonoid in the injection pump on the 92&93's. this will cause a hard start, and run poorly till warms up. It does something with the presure in pump which advances it.

Diesle engine quits after starting. 6.5 turbo chev


If your filter hasn't been changed recently then by all means do itand see if that helps. I change mine twice a year, spring and fall. You are probably right about the fuel pump but your best bet would be to pick up a copy of Haynes Diesel Engine Repair Manual, part #10330 first. It has an excellent diagnostic and repair section as well as testing procedures and repairs for these engines. It costs about $20 and could save you some money. Hope this helps.

Motor not running


The problem was a electronic box which controls the multi valve system on the fuel pump not the ERPS. The box had lost it's earth contact. These motors don't have a cut off solenoid like older diesels, a lot of trial and error to find.
Now a happy fellow.
