if it'll run on ether, gasoline, or intake cleaner being sprayed into the throttle body.. it ain't the injectors or motor. its pump related. I'd put $20 on the pump
also you might try checking the fuel pressure regulator its mounted in the return line going back to the gas tank has a vacuum hose from the manifold if it fails you wont have enuf pressure because it will dump it all back to the tank on a good reg if you un hook the vac line pressure will go up because the reg will close and not return any fuel to the tank ,the most common failure is the diaphram perforates ,best indicator is gas smell/dripping from disconnected vac hose jk
:hammer: have seen this before.get under truck with a rubber mallet or a 2x4 and slap the fuel tank as somebody cranks it over, 90% of the time if the pump is going bad it will start and even get you home... been there a few times!!!!
this is a common problem yes, now if you use aftermarket parts always remember that you get what you pay for...(cheaper is not always better ) and yes if the pump is bad it can run at (say 20psi) and truck will still not run, due to needing 60psi...
My '96 Suburban 7.5 has a hard start issue. It will start fine first thing in the morning. But once it gets warmed up and you shut it off and let it sit for a little bit you have to crank on it to get it to start. I have changed plugs and wires fuel filter and the pump seems to run fine. It has 80,000 miles on it and when I changed the plugs they were nasty looking. Oh and it uses oil too. Could this be the pump also or could it be something else?
Not being a smart ass or anything:messed:
Do you have fuel in the tank and are you sure the guage works????
True story a co workers truck "late 90s chevy" died the other day and he checked all the simples and determined the fuel pump was bad.... Instead of pulling the tank out in the snow he opted to cut a hole in his bed to access the pump, when he pulled the pump out of the tank he took a look down in the tank with a flash light and it was bone dry...... LMAO!!!!!! The guage said 1/2.....
