When I turn the ignition on the pump doesn't run. It's a stock 74 2.0L.
Are the two wires connected to the pump +/- 12 volts? I used a multimeter and there doesn't seem to be any voltage going to the pump. Is there a relay that supplies voltage or does it come from the ignition switch. I did check the fuses and made sure they were seated. Thanks! |

Not quite every way... The trigger points do provide the RPM signal to the ECU, and the ECU will run the pump if it detects RPM above a certain point. (50 RPM? I forget!)
But yeah, D-jet does provide a "priming cycle". --DD |
