long story...

just replaced my fuel pump with a 255 walbro unit last night. Also added a 6AL, coil and super conductors.

At first, fuel pump wouldnt prime at all. Dropped the tank (did it 6 times in the last 2 days) and made sure all connections were good on the pump itself.
Then i reviewed the "cranks but wont start" checklist, grabbed my multimeter and dug into EVERYTHING.

first off, no power to the connector at the fuel tank. So i checked the inertia switch and was only getting 2v with key on. Had a friend turn the key while i probed and ended up with more volts. So the inertia switch is also functional.

Moved up the relay.
Pink wire has 11.8, so it works. i removed the relay and jumped a few wires and was able to start the car, but obviously cant drive it that way.

replaced relay just to try it and it still didnt crank. A few random times the car started and just died after 15-30 seconds. Didnt sputter out, just instantly died.

Relay by MAF is functional and was clicking on and off when i was "jumping" the connector under the drivers seat.

does this sound like a bad EEC relay?


ive been working on this since 2pm yesterday.. starting to pull my hair out :bang:
 
For people to help, we'd need to know what wires you jumped at a given relay.

If your injectors have 12V Key-on, the EEC relay is functional. That's not to say that a leg of the circuit isn't open.
 
Cant remember which wires I jumped(not helpful but it was 4am and Iwas very pissed)going to swap out EEC relays tommorow, altough I can't find a parts store that has one in the system, and if that doesn't work, I've got a friend with a A9L I can swap in
