some one help me please. I have an sti v4 my98. Its started to run a little rough and now will not start at all. I have spark-fuel still no joy. Poured in fuel and it runs. I toed it to the local scooby boys and they say its electrical as the injecters aren't opening. Have also tryed a different ECU. Any one got any ideas

 

Check there is a ground on the block, I doubt that it is this...

If it runs by pouring fuel in then I would guess that it may be a ground, a fuse or a relay.. Ill check diagrams later if you dont get any better answers..

does any one know what controls the injectors if that is the problem. I have the need for speed and the thing doesn't start...... aaaaaahhhhhhhhh!!!!!!! help me brothers and sisters.

 

have checked fuses and relays. Will look at earths to the block. cheers

 

david could you check the diagrams for us as still nothing.

 

bttt

 

You have fuel??? Are you saying that the fuel pump is working, and you think the injectors arent opening?, or do you just mean there is fuel in the tank? You poured in fuel? Where exactly did you pour in the fuel?
If you think its the injectors, do they have a 12v feed?, and have you checked for a pulse signal with a meter at the other terminal while cranking?
Where you driving when this happened? Anything strange leading up to it?

Pump is working no problem there. Poured fuel into the manifold and it started to run. Checked timing and again its ok even changed the manifold over. It seams the injectors aren't opening so what do i do to fix this.

 

sorry forgot to say. Started car up and was very rough then became ok. Drove home and started it again ook no probs. In the morning same again. Drove about the 30 miles where it just wouldn't start and was towed home.

 

What error codes did the garage get?

 

They didn't get any because they haven't got any diagnostic equipment. Trying to find someone in the local area how could help. Does any one know where I get technical imformation on the ECU

cant remember where, but im sure someone here will put up a link for the ecu codes, and the 2 plugs under the steering column to access them. Chances are there may not even be a fault registered with the ecu, it depends what the problem is. Is all the wiring around the engine bay sound, no breaks, cut wires, shorted wires etc.
I once seen a legacy witha few wires, that looked cut, but may somehow have worn through, just near the multiplug beside the battery. It didnt stop the car, but the temp sender, and oil press light did give trouble. It also caused starting problems as the ecu wasnt receiving a temp signal.
Doesnt sound like your problem though.

 

will try and have a look at all wiring and double check everything.
If someone does have a link for the codes then that would be greatly appreciated.

 

There are error codes here, with a description of how to get them.

Hope you get it sorted soon.

 

cheers bruce will get these printed off.

 

ecu is showing no error codes. Problem seems to be that the injectors are not working. Where does the signal for them come from. They have 12v at there end.Taking it to a auto electrican as the mechanic has exhausted all possabilites. Any one else have a clue?

 

Signal comes direct from the ecu, unless somehow you have a faulty ecu??? and the injector drivers have burnt out or something.
Sounds strange. Do you have access to another good ecu to try it ( and hoping no damage occurs to it when fitted to your car )

 

that was one of the first things the guy at the garage did. Will see if I can get hold of another ecu unit.

 

yipeeeeeee. Its running. the injecters where jamed shut with crusty fuel. Getting them sonicly cleaned so she will puurrrrr again. cheers everyone.

 

Jammed shut?? Did you remove the injectors to find out, and what did you see???
Did you recently fill up with strange fuel, or has it just built up over a period of time?
Ever changed your fuel filter?
