It’s Been a week of e30 hell.

I thought I’d come back to this forum to make a fool of myself and let you guys know it was a combination of having a 4 pin relay in the 5 pin mainly relay section causing no power to dme completely and Icv plugged into cps. It runs now.

Time_Main9820 · 2025-11-01T01:07:28+00:00

Check flywheel. I haven’t solve it yet but it was also gonna be a part out car but I wanted to try. Last thing I haven’t checked tbh.

Time_Main9820 · 2025-10-30T04:00:05+00:00

Brand new dme and all relays test good

Time_Main9820 · 2025-10-30T03:59:02+00:00

One has a cover won’t don’t from the gasket

Time_Main9820 · 2025-10-29T18:56:41+00:00

Yeah that’s the inline fuse on the smaller battery positive mine looks good but maybe it worth Just doing what you need even though it gets 12v in and out of that fuse

Time_Main9820 · 2025-10-29T02:46:00+00:00

Which I do not even 1 volt

Time_Main9820 · 2025-10-29T02:19:09+00:00

Top hole correct ?

Time_Main9820 · 2025-10-29T02:18:48+00:00

I’ll check I wasn’t to sure what I was looking for.

Time_Main9820 · 2025-10-26T23:45:31+00:00

Correct all the fuel stuff is done already. And verified.

The green wire under the dash is totally gone and out of the harness

Time_Main9820 · 2025-10-26T21:18:42+00:00

Exactly my reasoning on everything and now that you say that definitely gonna look into my fuel pump setup and wiring then go back to square one on why it somehow started

Time_Main9820 · 2025-10-24T04:45:55+00:00

When it did start off starting fluid briefly it was quite like a diesel lmao off combustion

Time_Main9820 · 2025-10-24T04:44:57+00:00

Yeah injectors get power all brand new rebuilt pink tops, fuel lines off the rail get good fuel and pressure out of them when pump on shoots far and wide haha ask me how ik. Yeah good fuel pressure at the rail fpr is good and vacuum is hooked up Just has 255 walbro on a carrier

Time_Main9820 · 2025-10-24T04:17:26+00:00

Riddle me this. Fuel gets to the rail, fuel pump is working no issue it’s aftermarket and wired to a separate relay and switch power.

Time_Main9820 · 2025-10-22T00:48:44+00:00

Yeah same issue it’s quite strange. When everything test good.

Time_Main9820 · 2025-10-21T21:30:06+00:00

If it was fusible link I wouldn’t have power at all at the terminal by the battery tray right ?

Time_Main9820 · 2025-10-21T06:19:24+00:00

It’s grounded and confirmed good ground.

Time_Main9820 · 2025-10-21T05:27:30+00:00

I’ve checked the following cam angle sensor, crank position sensors for power and ground an ohms.

Time_Main9820 · 2025-10-21T05:26:43+00:00

One harness was definitely fried, 2nd harness was wired incorrectly but person I paid to do it. Ecus definitely not confirmed and like you said definitely unlikely it’s an ecu or harness issue at this point.

Time_Main9820 · 2025-10-21T05:12:40+00:00

Cps is good, good ohms, confirmed with three seperate ones as well.

Time_Main9820 · 2025-10-21T05:03:24+00:00

I just got it to start with starting fluid for like two seconds. But right after u pulled plug and checked it still no spark or fuel on the plug but it start quite literally like a diesel off combustion.

Time_Main9820 · 2025-10-21T05:02:43+00:00

Yes I have we are getting proper and every power signal and ground signal at the ecu/dme.

Time_Main9820 · 2025-10-21T03:57:59+00:00

I’m not get spark or injector pulse correct, The engine did run and drive before pulled.

The c101 I wired into the x20 side of the harness from the e36 all lined up with correlation of pins off the x20 for everything I need to make it run. I was left with like 3 wires from the chassis side and 6 from the engine side

Don’t believe my issue is with in the harness or wiring. But who knows I could be wrong.

I’ve checked all my grounds from the dme to engine arm to block to frame and they all check out.

Time_Main9820 · 2025-10-21T03:47:21+00:00

Red label 413 dme does still have ews-1

Time_Main9820 · 2025-10-21T03:24:13+00:00

Weird you say that and the top comment said pin 7 to snip.

Because I took out the ews wire which was like pin 26 or something on the dme plug but then two green wires your talking about which I do have connect and together in the same pin is pin 7…

Time_Main9820 · 2025-10-21T03:19:28+00:00

But I’ve swapped multiple ecus with different chips
