Re: 4AGZE Injectors Not Firing

Hi all,

Small update.

I've installed a replacement loom and got all connectors back on now except for the alternator earth and starter connectors.

I tested for voltage on the injectors and I have 12v on power and 0v on earth as I should do.

Can someone remind how to test the earths e1 e01 and e02?

Re: 4AGZE Injectors Not Firing

Hi all, It's been a while and I've had no motivation to do anything with the car. I have the loom off and decided to trace the injector lead grounds back through the loom. Seems I have them grounded in pairs and not as the multi-meter stated of having 3 on one ground and 1 on the other ground. The l...

Re: 4AGZE Injectors Not Firing

the top cover flagged for some reason so I went and looked, both my 88 an 89 GZEs are green 88gze https://i.imgur.com/siIElC8.jpg It's interesting that it's on the GZEs but my fuse box is from my car which is originally N/A.

Re: 4AGZE Injectors Not Firing

I'll have to do that once I've got the loom back on as now it's all off. Just one thing though...my fuse box cover from the engine bay fuse box, has '10a INJ' shown, but in the fuse panel itself there is no connector for a fuse in the casing. I do hope this is not the reason why it hasn't been worki...

Re: 4AGZE Injectors Not Firing

I've bought a replacement COR but I doubt that'll be it. We checked to make sure I was geting fuel through by undoing the nut on the fuel filter and obviously fuel went everywhere when I cranked it, so it shows the pump is pumping. The fuel lines are hardlined and there are no kinks so it cannot be ...

Hi all, Had a recommended mechanic round and checked through everything. The cam and ignition timing is all okay.

Re: 4AGZE Injectors Not Firing

From memory on my car before I changed the engine to 4AGZE, the resister pack bracket was bolted underneath the ignition coil bracket so they were earthed at the same time.

Re: 4AGZE Injectors Not Firing

Hello, I've replaced the square plug that goes from the engine hook to the strut tower, as I found it didn't do anything. At the time I didn't realise my intake earth wasn't working, so I replaced it with a ring connector on some 4mm cable and put that straight to the strut tower nut. It probably wa...

It's odd as my E1 is connected via the original ground point on the inlet manifold, but the E01 and E02 won't let me fire the eng...

Re: 4AGZE Injectors Not Firing

However, 3 of my injectors do earth back to pin10 and the other pin20 but they are wired in pairs on the power from the resister pack. Had a think about this and it is not ideal. The one injector will be getting a bit more current, and the three will be getting a bit less. Doubt if it is enough to ...

Hi all, How bright should the noid light flash on the injectors? When I tested 1&2 there was a little flash but nothing like the whole bulb illuminating. I do have a replacement wiring loom now, but due to it's cost I have to splice my alternator, starter, knock sensor and dizzy plugs onto it, a...

Re: 4AGZE Injectors Not Firing

Hi, This is not at all sorted. I reattached the wires on the ecu plug and the car didn't attempt to turn over. Put new earths back on and it fired up then died. Bridged the ports in the diag box and the car ran for longer but then spluttered and died. So is that AFM, COR and fuel pump? Took TPS off ...

Re: 4AGZE Injectors Not Firing

It's pretty stupid to be honest. I tested for continuity between E02, E01 and E1 on the chassis and found I had an open loop. At the time i determined there must have been an issue with the wires in the loom. As I had already put the rail back on again I couldn't be bothered to strip it all again, s...

Re: 4AGZE Injectors Not Firing

Sounds like an issue I had with one of my AE86s. Check the fuel circuit in the AFM. Try jumping the fuel test circuit at the diagnostic port. If the engine runs by jumping the fuel circuit then check the ground at the AFM plug. This is the ground bolted to the manifold, top of the runners under the...

However, I've got a photo of another set of ECU - 4AGZE AFM plugs which shows E1 being vacant as well.

Thanks for confirming this.

My E01 and E02 are both open circuit so this obviously has a problem.

Re: 4AGZE Injectors Not Firing

My noid lights arrived yesterday. I managed to test injectors 1 & 2 before I had to stop, nothing lit up.

Either I put them on incorrectly or I didn't see them flash, but there was defintely no flash from 1 or 2.

I will test the other two again later.

Re: 4AGZE Injectors Not Firing

My noid lights are coming in the post this week.

Out of curiosity I tested my compression which is 150, 160, 160 and 160 so no issues there.

My igniter isn't bolted down so could that create a problem?

I'm buying another gze loom and ecu for a good price incase one or both of mine are fubar.

I've got to take my loom off anyway, as it's too awkward tracing wires back with it all installed.
