Yup was going perfectly then went to go to work in it the next day it wouldnt go.

Havent checked for voltage at ecu was kinda avoiding having to do that haha.

My suspension was corect and my 1/4 tank of gas turned into no gas somehow so I put $40 of bps finest in and its still doing the flooding thing.

Will a standard gt ecu run yellows? as I have no Grey's on hand to swap out


Yup it will be bit rich on start but will run

How do you expect to run a standard GT ecu on a 3-plug?

Unless you've been running yellows on a 4-plug?

So we know it runs yellows. What ecu has it been running, what air flow meter, and what map sensor?

<Shale>: Blighter doesn't really have an accelerator pedal, it's more just a loudness pedal. You can change volume, but you won't go any faster.

Its a 91 bc5b gt sedan its got green afm bc5 map grry injectors and a brown sticker 4 plug e4 ecu so its stock.

I wanted to know wether my e4 ecu would run yellow injectors so I can rule out the stock greys injectors.

I dont have much in the way of bc parts at this stage but I do have a bg Brighton 220 to part and have parted a 97 bg gtb. So yellows are the best I can do right now.

Yeah they will run, will just be quite rich when cold. Once the O2 is online it will be able to correct them, but only while cruising, will over fuel like fuck when on boost.

But yes, will be able to startup.

Are you sure about that? Have you tested this theory?

I'm running yellows in my 89 rs with purple afm and a grey injector ecu and it's not rich at all hovers about 12.5 AFR on 11 psi with the td05

You could cut the tension with a knife here lol.

Wether has been extremely shiite so have done nothing to it for a few days.

A friend susgested the main relay was at fault. So I have a few things to try now. An ecu is on its way is from a v1 wrx.

List of ideas
Main relay
Ecu
Injectors
Test power to ecu
Unplug oxy sensor?

Would a shorted out oxygen sensor cause troubles like in having? Flooding on start up and no run.

Main ignition relay has two sides. One side powers the fuel pump and injectors, if that side fails, you have no fuel whatsoever. Other side poweres the boost control solenoid, idle controller, pressure select solenoid etc, this side will not affect start. Rusty had this side of the relay failed for two months before we got off our arses to find the fault, never skipped a beat, just didn't run or idle too well!!! We still drove it to the west coast and back like that though.

So it won't be main relay.

Injectors, I find it unlikely all 4 would fail at the same time, far more likely to see one fail, and then to run one 3 cyl.

Ok, so I've uploaded my favourite part of my BC manual to mega, section 2.7c.

https://mega.co.nz/#!cYgigbjC!7bVDskR5GQbfOkyIzET3yfNn6TiTBl3CmNfqEsEmJMM

You may need to sign up to mega to download that.

I want you to scroll down to page 56, trouble shooting for no engine start, and follow that checklist to the fucking letter.
DO NOT SKIP ANY STEPS, if you think you have tested or ruled out a step, tough, you get to re-test that step.
Doing it this way will soon make it very clear as to why you have no start. Where it states to test resistance across a wire, just testing continuity is usually sufficient.

Have fun, this should get you going.

From what I've been told previously, that ecu won't be any good to you if you've still got a WAIC
