hello, I have a 95 s-10 blazer 4wd. I have a problem with it.
Fuel pressure is ~60 psi, engine cranks over fine, getting spark, NOT GETTING FUEL. I pulled a spark plug, and had someone crank over the engine while I kept my hand by the spark plug hole, and no gas was blowing out. I used a digital Multimeter to check the voltage at the injector harness quick connect, and I am getting a constant 12.58v.

I have replaced the CPI unit, and have a computer on the way.
Does this sound like the computer?

Any Ideas?

Please help.

Hmmm, how about the fuel relay? (of the 3 mounted relays on the firewall it's the one closest to the drivers side fender...
I haven't checked that one (it had actually came loose from the firewall, and was dangaling).
What does that relay do? The fuel pump is running fine, and I thought it's relay was in the glove box.
