The pump will only run for about 3 seconds when the key is switched on.Then it waits for dist signal to come on again.
Need to check pressure at test port on fuel rail,I suspect the pump is out.

do you mean the pressure relief valve, this is located normally on the low pressure or return side of your fuel rail, this is designed to maintain fuel pressure in your fuel rail constant, e.g. steady running requires steady pressure, acceleration requires increased pressure controled by engine vacuum, if it was on the supply line you can not regulate the pressure supplied to the injecters. stopped engine requires no pressure so the pump gets turned off with the ignitionf

tune up-read your plugs and then check your timing. use timing light and double check with scan tool-most 91 305's were high outputs which

Fuel pressure? Do you hear the fuel pump running? Read the codes to see if ECM is still alive. Do you have spark at the plugs? Remember all motors need 3 things to run air, fuel, and fire at the right time.

1985 iroc tpi 305 can the fuel pressure be adjusted! i bought it used and it runs good but backfires and the exaust smells badly of gas has a new o2 and map sensor on it.


If it is fuel injected,the fuel pressure regulator is most likely the problem,if it is carbureted the mc solenoid could be the problem,or carburetor needs rebuilding.

No power to fuel pump.


Don't forget to check for a good ground at the pump, I've seen this problem pay for a new fuel pump more than once.
