Question about Chevrolet Cars & Trucks
I have a chevrolet 1998 s-10 changed the fuel pump and relay and cleaned the conectors and pump will still not prime and truck wont start
I'd look in to changing your low oil level sensor or checking the wiring harness to breaks in the wires going to the pigtail for this sensor. It is located in the oil pan and in other applications with this engine is rather easy to change.
This sensor will actually kill the fuel pump to prevent engine damage when it senses a low oil level for the engine. Given the items you've replaced thus far, this would now be my primary suspect for sure.

I am wondering do you hear the fuel pump when you just turn the key into the on run position not crank just in run and listen and see if you hear the fuel pump run for a second, If you don't hear it you will want to check for power at the fuel tank, and have some one cycle the key while your under the truck with a test light. Hopefully you have power and you hear the fuel pump run. Now if you do hear the fuel pump running then the next thing you will want to check is for spark, It could be the ignition module or pickup coil. check out those thing and I am sure you will be able to figure out whats going on. If you don't get back to me and we can try a few other methods. I sure hope that helps you out johnholley. and thanks for using Fix Ya Bear001

Well, one problem is, if its an 8.1, its not a diesel. The 8.1, or Vortec 8100, is a gas engine. The DuraMax is a 6.6 engine. There is usually not a priming system on a gas engine, because the fuel pumps will usually get it through the smaller filters used quick enough you dont need them. However, if it is a DuraMax engine, then right on top of the fitting where you mount your diesel filter, there is a primer pump and an air bleed valve. What you do is, open up that air bleed valve ( its a little black plastic octagon shaped thing on the top of the filter mount) then you pump the primer (the silver button looking thing) until you get diesel squiting out the air vent without too many air bubbles or gurgles.
