'73 1.7L D Jet I'm not getting voltage to the fuel pump. Continuity from relay board connector to pump. Pump works with direct voltage. I'm getting 12V to relays. Both pump relay and main relay are good (run headlights and click). 12V to fuse both sides, new fuse. Tried measuring voltage to pump when I power on the key and crank. Looks like a small registration on my voltmeter (in the mV range). Also tried test light--no power. Visits to websites for fuel pump troubleshooting given in previous forums (testing relay board, etc) seem normal. Considering fuel injection harness/III connector--I can jump this to ground to see if the pump runs, correct?? Any other options? Thanks! |

Grounding III results in power to fuel pump. What's the next step? ECU/Harness? |
