ok, on my 86 the fuel pump does register that there is gas in the tank, but there is not enough power to get it to actually pump the gas out.



there is not a 12v signal going back that way, not even close to 12



what would be the first relay to check on the car and where might it be?



ive been digging through the fsm to no avail and not finding much in previous posts other than where to start wiring a switch to the pump



if i am missing the topic please direct me to where i might find the answer in the fsm or other posts



thank you in advance

 

im sure there are some write ups on how to re-wire the fuel pump. But here is the cliff-notes.



Take an 8-10 guage wire directly from the fuse block or the battery and run it to where the factory fuel pump connector is (over by the shock tower). Buy a 30amp relay from the auto parts store and a 30amp inline fuse. Hook the + wire from the battery to the relay, ground the relay using the same guage wire, and use the factory source power lead (on the pump connector) as the trigger for the relay. Use the 8-10 guage wire on the output of the relay to run directly to the pump, bypassing as much of the factory wiring as you can. Make sure to use the inline fuse in between the relay and the pump.

With that setup, when the ECU sends power to the pump, it triggers the relay, sending a full 12V+ to the pump through the wiring you sent from the battery.

 

pimp thanks, guess it is a trip to o'rielys tomorrow then
