Having problems with your 1994 Chevrolet S-10 ?

Intermittent fuel pump

\015 With key on fuel pump runs erratically. I've troubleshot the circuit back as far as the green/white striped wire coming from the ECU. This wire sporatically loses voltage straight at the ECU. Either, something is telling the ECU to cut the voltage to the pump, or the ECU is bad. I really think the ECU is receiving a bad signal from somewhere else, but I don't have enough system knowledge to know what has the capability to do so.\015 Posted / edited by AnonymousUser on : 25-09-2017
