Hey guys.. well.. I have my haltech hooked up. For the passed few days, when I would turn the ignition key to on, the fuel pump would primer for the 10 or so seconds. Well.. after putting back my interior yesterday afternoon. I go to turn the ignition to on to try and solve a fuel leak problem I had at my fuel rails and NO primering of the pump. I replaced the positive terminal with a really good quality one and re hooked my power and ground wires on the battery. I used a circuit tester to help locate the problem and this is what I found. The haltech is getting power. I hooked up the solid orange wire to the battery for the fuel pump and the orange with grey striped wire to the fuel pump (keep in mind its been working fine for the past few days). I checked the fuse.. The fuse is good and theres power going in and out of the fuse block (on the orange with black stripe and orange with grey stripe wires) for the fuel pump as well as the main engine and injector fuses. Now where I tracked it down to is the fuel pump relay. theres power on the orange with black stripe, but no power on the orange with grey stripe wire, which is the wire that hookes up directly to my fuel pump. I had a few relays laying around. So I switched out relays and no luck still.. I tested the power on the main engine relay and its getting power going in and out of the relay. So I switched out the relays with the main engine relay which I know was a working relay. Still no luck. I put the relay back on the main engine relay and it works fine still. Any ideas on what it can be guys?? Im stumped. I have no clue what else to look for.. Thanks guys.

Is the Haltech it self powering up? remember theres a wire that turns it all on, the grey activation wire, and there are 2 of them, its the same wire, but make sure you put power on that too, can you go online with the haltech when this is happening?

Oh, and also. The troubleshooting section of the manual says if the fuel pump doesnt primer check for clicks on the relay. Well when I turn the key to on, It clicks.. But just once along with the main power relay. It says to check pins 7 and 25. That would be the Red with white stripe wire coming out of the fuse block correct? If so, that has power also.

Well.. I havnt hooked it up to a computer yet. I dont have a laptop. Just my personal PC and its about 35ft away. And I cant find a cord that long :/. I went to buy a cheap laptop from walmart the other day but they were out. Anyways. Theres 2 grey wires? On my harness there is just 1. Theres a Grey, a black, a solid orange, a orange with grey stripe, a red, a green, and a black. I have the grey tapped into the IGN1 under my steering column (my apexi AVC-R boost controller is tapped into this grey wire for power). The black goes to the negative side of the battery along with the red and solid orange going to the positive side of the battery. The the orange with grey stripe goes to the fuel pump and I have the green wire wrapped and tucked away.


EDIT: the apexi AVC-R is getting power thru the grey wire.. So I dont see any reason why the haltech wouldnt. Also, if the haltech wasnt getting power with the ignition on, why would my circuit tester show power going thru all the wires only when the ignition is switched to on?

Grey wire man! Grey wire!! Is it getting power, go online with the haltech and check it its powering up, if not, you're not feeding the grey wire.

Okay.. dragged my desktop PC outside (neighbors lookin at me like im crazy. Hooked the haltech up. turned it on.. It booted right up.. Haltech Online. Fuel pump still not primeing.. still no power in the orange to grey wire.. :/

frank,
since i don't have all the wire colors in front of me, i can talk a lil generally. a relay uses power, ground, a wire to trigger and the power out of it.
so, either your relay is bad - tested others so not likely
you dont have power going to it
your ground is no good
or your not triggering the relay

i am on wiring patrol on saturday, after i finish wiring a harness for my buddy i may be able to stop by after if your still having problems, i have a laptop.
let me know....

That would be really cool if you could come by only thing is I work at 5:30Pm tomorrow night. See, Im getting power going into the relay. Im just not getting any going out of the relay. At least thats from what Im understanding. Im getting power from the fuse box to the relay on the pump (the orange with black striped wire). Then out from the relay is the Orange with grey striped wire which goes from the fuel pump from there. Thats the wire im not getting power to. Im suspecting maybe a bad ground on the relay. Im not sure if this is healthy to do. But my relay has a orange with black wire, a orange with grey wire ( Im assuming those are the power, two grey wires (hooked up to the same terminal on the relay which im assuming are for the trigger) and a black with yellow stripe which I assume is ground. Now when I test each of the wires, the orange with black stripe wire lights up. the grey wire lights up and the black with yellow stripe clicks. but the orange with grey wire dont light up (no power). I hope that all makes sense

put one test probe in the wire that lights up, and put the other end in the ground suspect. if you know you have power there but it wont light up, then its not grounding, so check the ground.
