Hello teeners
Looking for some advice please I have a 72 V8 conversion (I Know not a real 14) Really fun to drive I just tried to start it and I do get power to dash and radio but the fule pump cuts out and no crank when I turn the key to the full starting position. The 2 things I have notice 1 Battery was low (Now Charging) 2 No cranking no clicking nothing. 3 Fuel pump cuts out 4 flashers tied to the e-brake keep flashing could it be the e-brake sensor? Clutch sensor/switch? Starter? ignition switch? Checked all relays and fuses I can find All seem good. Thanks Mike |

The relay/circuit board in the engine compartment is just a pass through for the started circuit, none of the relays on the board have any impact on the started circuit.
When you are checking for voltage at pin 1 of the 14 pin connector and then again at pin 6 of the 12 pin connector, are the harnesses unplugged or are you back probing the connectors? Some time a connection can be just strong enough to carry the small voltage of an ohm meter but looses connection with more voltage or load. Also some time the physical force of a connector moves thing enough to break a connection. You can also test for voltage at the circuit through the panel by testing at T2 (II) or T4 (IV) of the FI socket on the board, both of them are tied to the same circuit. If you apply power to the wire at pin 6 of the 12 pin connector does the starter crank? Jim |

I jambed a wire into the socket pin on the harness and turned the key getting voltage on Pin 1 of the 14 pin connector but no voltage from pin 6 of the 12 pin outgoing connector. I think applying power to pin 6 is a good idea would i connect Plus 12 to pin 6 and the neg terminal to ground? |
