I have a 95 S10 with a 4.3 vortecand a cpi fuel injection. I've replaced everything but the fuel lines and It won't start. The pump only primes it to 22psi. Any help?
I can start the truck when I pour gas into it. But only for a second. It with
crank fine but won't start. It only gains to 22psi when I turn on the switch.
Every thing tells me it should be 52 psi to 60 psi.
I can't get the fuel pump to activate with the test wire under the hold it's
been down a month and I've spent $500 on it already any help would be
You need at least 50 psi to fire the injectors. It's supposed to be between 55 and 65psi. Either your pump is weak, the regulator on the back of the injector spider is leaking/bad or the lines inside the plenum are bad. 22psi will not run the truck
