Try now?

I can see it and i can hear that sumumabiatch cranking over like an old tj hooker. My gut says the Pump is not being told to deliver fuel by the ecu.

so how would i fix that/which wire? im getting confused(hate electrical gremlins!) i am waiting on a call back now from yury from wiring specialists...

ohhh wait, you had Yuri do it? Hes the man...its not your wiring...its something else.

no no-i am asking him about it. i might end up sending it to him tho(should did it in the first place )

Yes, do yourself the favor and send it to him

talked to yuri. he said there is really no point in sending him the harness if i find no problem, which there is obviously a problem-i just cant find it. he also said that the wiring can't be that screwed since the coilpacks are firing. im out of ideas. maybe i should get my hands on a new sr engine/ecu harness and just send that to him...?

No, dont do that. Take a small break...think about it, and then hit it hard in a few days. Sometimes looking at a problem a few days later can refresh the eyes. Also, keep us posted we will do what we can to help. Do you have an FSM?

no, but i have been tracing the wires according to the chilton's 240 manual i have. i just spoke to yuri some more; he says the yellow and black(thick wire)wire from the fuel pump relay is supposed to be a hot wire, and that i have lost a ground somewhere if it is not. so i checked it out, it is not hot, but the black w/purple, black w/white(skinny), black w/white(thick) coming from the relay are all hot-which one of these is supposed to be ground??

woa...hold it...lemme go look for that link

alright thanks man, i will be ripping the harness out either tommorrow or wednesday and throughly inspecting(hopefully correcting the problem). i just used some dreadful starter fluid and got it fired up, so i know she runs beautifully and i know that the fuel/injectors is the only thing holding me back. i'll let you all know what me find...

keep us posted

there is a high possibility that your ECU is bad... I had this problem... only mine decided to poop out when I was driving down the road... the ECU just decided to stop telling the fuel pump to turn on. I about went crazy until I got to the last thing.. the ECU.. swapped it with a friends and then BAM fired right up... betcha that's it...

well, ill try it-just have to locate another because i really don't know anyone aroung the atlanta area with an sr... thanks man, maybe i'll try this before removing the wiring. and i'll let all know what happens. oh yea-tiger, did your injectors also stop working??

oh yea, i adjusted the timing when i started it with the starter fluid and it's now 98% perfect(won't adjust it anymore til she's running as should be-i lined up the punhole in the cas wrong when first installed) so i can rule the timing factor out...

What # ECU do you have? Could be the wrong ECU or a bad one.

code 62 ecu...

yo leroiboy i got the same problem you had i got it cranking now but it wont fire what steps did you take to get it fired up

well, im getting fire, just not fuel or injector(s) operating. but to start it, i MODERATELY sprayed starter fluid in the nipple of my intercooler piping and it runs swell-all i gotta do is get the ecu or wiring(whichever one is the culprit)to do electronically what i did manually. email me if this didn't answer your question and MAYBE i can help you,as i am learning all this myself. but as far as spark, i have fire at all four coilpacks nice and strong.

I dont know why it took you all two pages but its most likely the fuel pump relay. If the pump is new and its not priming and there is no power at the pump then its either the relay or the wiring going to the relay so try to start there and stop testing all the other crap people are saying.

I swear common sense avoids some people....

ok, common sense only avoided you, if you don't wanna help stay out of this thread *** boy. yes, i have tried 3 different relays because common sense told me to and should have let you know that yes i did do so. if you read

if you read this earlier in the thread, maybe you could tell me what is wrong right here instead of just coming and being the wise guy. so from the above quote, what is wrong with that picture and do you know where i should go in the harness to fix it?

I did read before that you had been looking to the relay and none of my post was directed towards your rather to the people telling you what to check...

Also Yuri is not that great of a wiring guy I mean he knows what hes doing but he takes short cuts which at times come back to hurt you. Sounds as if his wiring may be causing your problems now. Youll need to trace the power and ground sources for that relay and figure out why you have 3 hot wires and the one you need hot is not. Ignore everything else because your relay is your main issue right now.

ok, my misunderstanding. i am going to search through the relay wire tommorrow then and see what's up. would this likely solve my problem as to why the injectors are not working as well? thank you

mine wont spark or get fuel,i checked the fuel pump relay and its all good i have no clue what to do

leroiboy your fuel pump relay should have four wires two skinny two fat. If you disconnect the harness from the relay and recheck for power and grounds you should have two wires with 12volts those should be your fused wire ie coming from your fuses. Now the other fat wire should be ground because it is grounding through the fuel pump windings the other small wire should have nothing at all (should be other small wire) that wire is grounded by the computer to turn your fuel pump on. If you have no ground on that wire then no fuel pump, I am wondering if you even have ground flash at your injectors I assume so because you have spark. So you have to figure out why your relay is not being grounded by the computer. You could just ground the wire that is controlled by the ecm engaging the fuel pump and see if it starts but make sure you have the right wire though good luck and I hope this helps.

This is the first time I have ever heard anything negative about Yuri. Shortcuts on a wiring harness? I would define that as maybe buttplugs or crimps? I have a harness done by Yuri and I didnt have any crimps or buttplugs...if he wear to take shortcuts do you think Greg(Hitman) would allow him to be a sponsor, not only that but the negative posts would be bountiful.

Anyway...

leroi...dude...I hate to see what you are going through.... Any luck on those 12v readings that boriqua suggested

no not yet, i will try sometime tommorrow morning and will post my findings around noon. i really thank everyone for their help. xdabsx...i will email you sometime tommorrow as well, but you should look through this thread, as these folks are giving some very knowledgeable advice.

Most of Yuris Harnesses from about a year ago he would wire the ECCS relay incorrectly which would cause SAFC and Power FC user no to be able to save changes to their map. He may have solved this now but the problem occuring in this thread would be a direct link to his wiring unless the car harness wiring was messed with.

LIke I said Yuri knows what he is doing but has been known to take short cuts to get harnesses in working order.

Also my emails with him I got short answers to my questions which never really solved my problem so i screw him and figured it out with the assistance of my roommate and wiring guru. He knows the SR, RB, and pretty much any harness he works on down to every wire.
