Electrical problem 87 CRX SI fuel injector system
My 87 CRX has no injector pulse, nor does the fuel pump power up. The main relay is good (I tested it and the ECU), but there is no power to the injectors.
Does anybody have a wiring diagram for the fuel injector system?
I need to know the full path from the battery to the injectors.

have you checked the fuel pump itself to see if it is o.k.? check all of the grounds, particularly the one for the ECU - not sure where it is on the 87, but on the 88-91 it comes out of the engine harness and is connected to a bolt on the thermostat housing - i would bet it is in the same general location on the 87

Thank you!
I fixed it. It was the ground on the thermostat housing. The bolt was stripped and the connectors were dirty. Runs great now!
Thanks for the diagram. I would never have found the problem without your help.
