Question about 1994 Chevrolet C1500
1994 chevy k1500w/TBI 5.7 l engine will not start, put gas in TBI starts, changed filter, checked, gas is flowing at carb with key turned, changed injectors no start, pulled injectors car ran with gas just flowing into carb without injectors, put injectors back in no start, checked for electricity in wires to injectors w trouble lite seems to have electricity. Any Idea what is keeping injectors from picking up gas and injecting? Trouble started when ran truck out of gas.
This injector set-up needs a specific fuel pressure supplied to the fuel rail to even start, much less run properly. The fuel pump is immersed in fuel inside the gas tank to keep it cool and not burn up. Running the fuel level low causes more heat in the pump and interuptions in proper fuel pressure. AC/Delco pumps have proven to be a reliable fix, the aftermarket pumps only last for a month or two sometimes. Check fuel pressure under the hood and power and ground to fuel pump at electrical harness at top of gas tank. This truck needs a fuel pump.
