how do i wire my fuel pump direct.

[spitfire7]

i just did an sr swap, and im not getting any fuel. so i want to run a wire from a 12v to see if itll turn on. i see a blue/red, yellow/blue, yellow, white/purple, and black. whichone of these do i run a wire to to get power to the pump. its a 91 coupe with an s13 red top.

I don't know how to do it by heart, but if you want http://www.deatschwerks.com/ has a kit.

ok easiest way to do this is a Relay

Do this out of tank not in tank!!!

set it up like this take your fuel pump power and run it to a Relay on the switch side with 16 gauge wire

Ground the ground wire to the chassy if youd like.

Next run a 16 gauge wire to the power side of the relay and a switch 12v to the other side of the relay and then ground the ground side of the relay w/ 16 gauge wire.

No what happens is when you click your key on the relay will click power directly from the battery to the fuel pump which will give you direct 12v to the fuel pump.

thats cool , but what wires do i hook up , u know color wise. its 5 wires which ones are the ones that i hool up to the relay and which ones do i ground.

[spitfire7]

can any one tell me which one is the power wire, and which is the ground

My advice is to get it running right first. Countless times I have had people tell me they have jumped the fuel pump because it will not turn on. This means the ECU wiring is not correct, and you can expect other problems with the engine until the underlying wiring problem is fixed.

thanks, there was a connector close to the firewall that i overlooked. when i hooked it up it fired rite up. im glad that i didnt have to do that.

forget the wire direct. if it dosent work then its a problem. i found the problem, a connector. but she was still runnin very bad. so i tried to adjust the timing by getting it to top dead center. and it didnt start at all. so i put the cam angle sensor in the way it was suppose to be and it still didnt start. i was tring to get at top dead center and was still off. what appeared to be top dead center on chamber #1 actually #4. i was so discusted, and just thought it was just backwards so i turned the marks on the cam angle sensor 180 degrees the other way and it started up so perfect i was just stunned in amazement. so all u guys gettin spark and fuel, and it still isnt starting, and u have it at top dead center turn it 180 degrees, and it just might start. good luck.
