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.

cpi

thanks for the reply. I'm sorry I wasn't more clear. there is NO LEAKAGE. It is a new CPI unit, no washing, nut kit not leaking,
Just Injector not firing (it appears). It is like the injector output is on all of the time (constant 12.58v).

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.

Generally Injectors see 12volts all the time, the computer grounds them to trip them.

im not sure about cpi injectors but i would imagine the ecm would still ground
