Have no power to fuel pump after ls swap in 94 CX Hatch. Any suggestions. Checked voltage @ fuel pump and showed no power. Thanks.

I get no prime ( or clicking from my relay), gonna swap it out with one from my other hatch and hopefully that should do it. Any suggestions as to what else it might be. It ran and drove there (a few days ago). Now, no clicking, no fuel at all. Would a bad relay show no power at the pump ?

i need to know this too.

It hasnt run since you did the swap?

If that's the case, check the ground on the thermostat housing. If that ground is off, your fuel pump will not run.

yup, seems to be the common problem, i'll check it tomorrow before I change out the main relay. I didn't try starting it yet, but it ran when removed, now it seems to not prime. Ground 1st..then relay. Thanks Slo.

corrosion on the thermostat ground. Seemed to be the problem, until again, after running and re-starting, no clicking ( fuel priming). Gonna swap out relay.

CHECK WIRING AT THE STRUT TOWER AND ECU. ALSO CHECK ALL THE GROUNDS. THEN CHECK YOUR MAIN RELAY UNDER THE CONCOLE LEFT SIDE.

Thanks..i feel like it is a ground problem as well. Gonna clean them tomorrow and re-connect. If not, got the main relay if need be.h

i had the same problem with my honda it was a 15 amp fuse to my ECU so check that and see if its blown and the main relay is 57.95$ at the honda place

Thanks...fuse checked out okay...main relay i stole from my old 95 dx harness and I cleaned my grounds. It still won't start up on first try though...grr.

try grounding the fuel pump directly that will for sure tell u if its a bad ground
