1992 Civic,... I replaced oil, filter, fuel pump, main relay, battery, ... and yet Engine light stays on, no 12v to the fuel pump.. whats interesting is that after 5 mins with the key in crank position the Engine light turns off and 12V is supplied to the fuel pump and then i am able to crank and run the engine. I let the car run on idle at 2000 RPM for about 10 mins and then the Engine light comes back on with the engine still running. I turn off the engine, crank it back again and the fuel pump kicks in after 1 min and engine light goes off.
I'd appreciate any feedback, thanks.
