Well I switched to a carb, and threw the old computer in the garbage, now everything works but the starter; no fire? Is this the VATS? How do I wire around it if it is? Thanks!

I just got rid of my comp and went to a carbed engine cut out all the comp and wiring, I had trouble with the starter, no power at all. After three days of looking I found a solenoid in the driver’s side kick panel behind some heavy tape (behind the metal). There were 2 heavy yellow,1 heavy green/white stripe and 1 small green wire going to it. I believe that the small green is supposed to pull the solenoid in but mine didn’t for some reason. Open the solenoid jumper a yellow and the big green and try the starter mine worked. Still only starts in park & neutral still. I’m working on a 89 RS. I hope this works for you.

 

"throwing the computer in the garbage" was pretty stupid. Now you have to figure out why VATS wont let you start the car. DOH!...

My ECM is still in the car, and nobody laughed at me for still having an ECM in my carbed car yet. I just didnt want to create unecessary problems for myself.

 

I didn't really throw it in the garbage cool guy, It was a figure of speech.:lala: But I damn sure ain't puttin the piece of **** back in the car just so I can start it. And I didn't pull it out so people wouldn't laugh at me. Anyway thanks for the help!

 

yeah hey cool guy vats only controls your electric fuel pump and other than that it sends a 30 hz square wave signal to the ecm so the injectors will fire. i hope your not running the carb off the electric fuel pump anyway if so that is probably your problem. i have totally gotten rid ofmy computer and electric fuel pump and i still cant start the car. it neverr had vats in it either so i knwo that isn't my problem. you need to tie that fuel pump line to a voltage source that is swicthed with your ignition and then find the starter problem like the one i have now. so there is your first step.

 

Well apparently I'm not as cool as you and don't run a piece of **** aftermarket electric pump. I guess my 11 second car isn't fast enough for me to upgrade to a Holley red, blue or something like that. Sorry, I guess for now I'm going to have to stick with the stock pump...

VATS WILL keep you from starting the car if you didn't bypass it, beacuse, dumbazz, it also disables your starter. So yes, if this guy was smarter (and didnt call the ECM a piece of **** just for the hell of it) he would put it back in its spot and start (no pun intended) enjoying his carburated vehicle.

 

Well I didn't call it a piece of **** for nothing, I called it a piece of **** because I personally didn't think it was up to the task of running my set-up. I had a Super Ram on it, set up with factory Mass-Air, custom burned chip from Ed Wright.(I bought it this way) I think carb is the way to go for what I'm using my car for. And furthermore; I will not put the ECM in my car just to get fire to the starter. I am not worried about fixing the problem, I know I can track it down, In fact I temporarily am turning the car over from inside the car now. I just thought someone like mtspace4 that has already experienced this problem, might know a shortcut. Thank you. I really wasn't hoping for a smarta$$ to start talking ****. So since you didn't offer ANY useful info, shut your piehole!

P.S. I am runnning a stock fuel pump as well, with a mallory 3 port regulator.

 

Oh okay... well happy hunting buddy! hope you find the "problem". Later...

 

hey listen cool guy if you knew what the hell you were talking about you would know that the vats module only sends a 30 hz signal to the ecm to fire the injectors, if bo ty guy there didn't junk his vats module and he still has the same key he used to with the old setup he had then vats shouldn't be a problem anyway. dont mess with me on this i know this stuff straight from the gm tech help cuz i converted my car from maf to sd with the need for a vats input and i know what i am talking about. he doesn't even need to do anything to his vats. i was saying he could by pass the fuel pump part of it if needed but if it is still functional then there is no problem with vats and not starting his car.

 

VATS on a 89 DOES control a starter enable relay and fuel via a 30hz square wave to the ECM, just read mtspace4 's post to locate and bypass the starter enable/disable relay







and please stop arguing just because you don't know the f***ing answer

 

hey ok i need to know how to get my 85 iroc to start.. i have ripped out the computer and harness.. wires were melted and such from last idiot who owned the car. i used the computer for a core return to buy a new ecm for my 87 GTA any way i am having the same problem but can't find the 'noid he is talking about with the 4 wires 2 yellow and one green white, and one green. i need to get my car started and i know the starter is good and battery is charged so please if anyone knows where this 'noid is on an 85 please let me know and how to bypass or a different solution to this problem

 

an 85 wont have it(it is a relay), only the cars with VATS (IIRC 89 up) have/had it

 

ok so where is my problem then??? i need to get this car working

 

is it wired right?

 

yes it is wired right.. it isn't that hard. i know it has something to do with the ecm not being there but i dont know what it is that it needs to start
