the other day the car started for a split second then died from lack of fuel.

i check all the fuses and i hadn't blown one and didn't a loose connection on the bay-car connector. but one of the relays was at first click its nuts off but then nothing.

so i checked if the pump was dead and it doesn't seem to be.

but i wasn't getting a 12v feed to the pump when there should be. i was only getting 0.01v for a few seconds then nothing.

so i replaced the relays because they seemed to be the likely cause. the car tried to start for a split second again then died again of fuel starvation. (also i didn't here the pump prime)

but now i'm getting a constant 0.18v to the pump regardless of the key being in the ignition or the relays being plugged in.

what could be causing this? any suggestions.

also this is a ph1 172 engine running in a mk1 valver shell

172 relays

been chatting to a few people about it and it seems its most probably a loom problem so going to remove it tomorrow and have a look and see if its rubbed threw anywhere.
