FUEL PUMP NOT COMING ON ?

[migsk8]

ok so i was working on my car yesterday and i dropped a tool and sparked the battery. my car started bogging and i fixed that for now. but i have another problem. i went around the block, shut my car off and tried to turn the car off. my turbo timer counted down but it didn't shut the car off, so i disconected the battery. now i put the battery back on and the e brake stays on weather the car is on or not. the fuel pump will not come on at all. also my apexi avc-r will not come on. whenever the avcr comes on, the fuel pump works. anybody know whats wrong?

here are some of my guesses

-bad lower electrical part to ignition switch-bad ecu-bad wiring avcr to furl pump (i dont think such wire exist?)

any ideas?

anyone?

Have you checked all fuses? If all you did was drop the tool on the batt it should just blow a fuse. did the too touch the car or just the two batt terminals

battery to car. im gonna check all fuses this morning cuz my car is over at my friends house. how do you check a relay ?

[240_SeX]

That could be an issue, that kind of amperage can do some serious damage, make sure to check all fuseable links as well. relay testing depends on the relay, the eaisest way it to listen for it to click when its powered up. If ther eis no clicking test for power and check resistance across certin terminals on the relay. or you an always swap out the suspect relay with a known good relay that is the same

there is no power going to my fuel pump period. im gonna go try and switch out the suspected relays for other one in the car. ill let you knwo what happens

ok so i switched out the relays and the fuel pump still wont come on. im stumped, someone throw out some suggestions

RECAP

-ebrake light stays on-avcr does not come on -fuel pump will not come on-fuses and relays are fine-if the avcr comes on so does the fuel pump-i switched out the electrical part to the ignition switch and still nothing

HELP !

I've had the same problem before with my SR but the thing is I didn't drop anything on the battery to cause sparks. The problem was my ECU. It happened when I was installing the Z32 MAF. I kept messing with wiring trying to get it to start but shortly after, the fuel pump wouldn't even come on. So I went ahead and opened up my ECU and found a problem....lifted track on pin 36. In short, make sure you check your ECU. I believe it is something electrical, check the fuses too as well.

Check the wiring. Make sure you're getting 12V where the relay box is. There's a thick white wire, I don't remember if theirs 2 or 1 but make sure you have 12V, there. Also check for voltage at the fuel pump and check the wiring to the fuel pump.

i bought another ecu and no such luck. but ill check the wiring to pin 36. thank you

i dont have power coming to the fuel pump, and i also have no spark

Sounds like you've got a loose wire somewhere. Check for continuity or just follow the wires and see if anythings loose. Or possibly a disconnected ground.

so a that can cause both spark and fuel to be out ? thats all im checking for today

[Sil80315]

Check the wires that go to the green and brown plug that we have to cut and rewire for sr swaps..you might of melted a wire..also check your connect where the avcr goes into the harness. see if any contacts are rubbing against eachother. you can always hotwire the pump to see if the pump is working and see if the car will start.

ok so today i said F this and took all exposed wires cleaned them, crimped them, and re taped them, i also cleaned every ground on the car. and the car works now. i was just my horrible wiring, idk what the problem was. but i went to town on the wiring
