1990 chev 5.7 Problem with check engine light coming on and oil guage
I have a 1990 chev 5.7 I have rebuilt the motor and new oil pump when it’s warmed up and only when at a stop light or stopped and when in reverse or drive the oil pressure guage drops and the check engine light comes on. I have replaced the oil sending unit and bought a new oil guage for the cluster too. I have tried a different instrument cluster too but still have the same problem. Any suggestions welcomed
