I have a 1991 Honda Crx and the fuel pump is not pumping.
Car: Honda, CRX, 1991 - Back to Fix-It - Honda CRX Repair Manuals
Q.I have a 1991 Honda Crx and the fuel pump is not pumping. There is no voltage coming to it, and after hooking up a seperate power source directly to it I know it works. I have replaced all the fuses and main relay. Why isnt power getting to the pump. I checked most of teh wires and everything seemed normal. any ideas?
Answer There must be an open or loose connection. I would start by checking the connection on both sides of the circuit. If thats fine, then do continuity test on the circuit. More then likely its a loose connection.
Which wires did you check?
Addition I checked the wires that connected to the fuel pump, and the ones going in and out of the relay.
Answer Do this, Using a digital multimeter check for voltage on the wire that powers the fuel pump. Just connect the positive probe to the B+ wire and the negative to a good ground. If there is no voltage on the wire, then the problem exists on the main relay or before in the cicuit.
If there is voltage on the wire but not at the end of the connection, then you have an open between the main real and the pump.
Basically just check for voltage ad different points in the cicuit, once you know where the voltage is missing, you can find the culprit quickly.
