I was given a 1994 s10 Chevy Tahoe vortex blazer??????? It's either a S-10 pick-up or it's a Tahoe or a Blazer not all three . So which is it ?

Sounds like the ignition module. Do you know if it is tbi or cpi?

It's the check vale inside fuel pump module . Testing for failed fuel pump check valve

try replacing the fuel regulator,or is the oil cap on tight?the fuel regulator works on base vacumm

you probably need a fuel pump relay its on the driver side rear corner under the hood

did you change the spider under the intake

not enough pressure to the fuel rails for the injectors
