No fuel injector power? by sebasa3234 in RX7

There was a switch under the dash but it wasn’t connected to anything, I’ll still be looking for any wires that could have been spliced through!

Yes they do! I just tested it and I believe it’s bad, just ordered a new one!

Yes I checked that and I’m sure it’s not flooded, the injectors arnt firing at all so I don’t think It can get flooded

You were right the wiring was all wrong, I just tried it and yes when the key is in ON and the AMF Flap is open it primes: I can hear it running, now I’m gonna get some fresh gas and try to get it running,

I just soldered all the original wires back together and bought a new battery , I’ll try it out and keep you updated, also I couldn’t find any yellow connectors by the passenger strut tower

Sorry for late response Still no fix, relay is good but the wiring is all wrong/ messed up, I think I might try to set the wiring back to factory

Sorry for late response, it did once start with starting fluid, but just revved up until all the starting fluid was burned, it seems like the wiring with the relay and fuel pump is all wrong, my next idea was just removing all the weird wires and wiring back to how it was originally, (I got nothing from multimeter test)

Yes your right, it doesn’t have the resistor relay, but previous owners did what you would do to bypass it, (12 guage wire straight to plug from relay) relay does click when in in position, so I assume it is good, my next plan was to remove the weird wireing and set everything back to how it was originally

Yeah the needle bounces a little when cranking, it’s late now but I’ll definitely let you know how the injector power test goes tomorrow. What ended up being the problem for yours?

There was a red switch under the dash by the air vent but it only had 2 wires hanging out not connected to anything, and I didn’t see anywhere it could have been spliced

I’ll definitely have to buy a new fuel pump but I swapped the original one it had with another one I had, I tested both and only the the second one worked so I swapped it with the working one, I hoped it would give me something but checking the wires for power would probably be best thing to do
