Engine Performance problem
1990 Chevy Blazer V8 Four Wheel Drive Automatic 205000 miles

Truck will not start, as though theirs is no gas. If I pour a little gas into the fuel injectors, the truck starts immediatly, then dies. Is this the fuel pump?

If so how do I diagnosis if the pumps bad, an electrical problem, fuel filter etc.

Do you
have the same problem?

Hi scott riley and welcome to 2carpros

When the last time you've replaced the fuel filter? If okay Tee-in at the fuel filter and check the fuel pressure should read 9-13psi
