Ol cranks but won't start I am new and just purchased a 1994 Chevy Blazer S10 4.3 I believe. I have a good strong battery and plenty of fuel. On the recommendation of the previous owner I replaced fuel tank had a hole in it and the fuel pump. The engine cranks but will not run unless I put fuel right to the intake. Burns that fuel and died. Like I said I'm new to forums and stuff I'm 60 I consider myself a fair shade tree mech. As in I know how an internal combustion engine works lol
sorry it's 4x4 auto standard factory issue if I can get you any more info that will help just ask. Thanks any help would be appreciated

 

There is a "sticky" thread that covers the crank/no-start situation.

It sounds like a fuel problem. A standard thing to check on the Blazers is the fuel pressure in the supply line immediately before it enters the engine. There are specs for what the pressure should be and for how long it should stay high.
