Hi

Replacement ECU in. I also used the digifant YouTube video and multi meter to check all the connections and tighten anything that looked loose.

New oil and filter, and it's running sweet as a nut.

Again thanks for your help.

Cheers

A little bit more time spent on the gearbox. I took the crown wheel and open diff down to a mates and used their neighbours pillar drill to drill out the rivets.

I snapped the drill bit on the last one 🤦‍♂️ so ground the rivet down with a finger file and tapped it out. Also tapped my hand in the process!

Went to Dan's and fitted the Quaife to the crown wheel and torqued the ARP bolts to 54 lbft.

Gave the casing and gears a reasonable clean down with brake cleaner.

Sealant applied to the casing and bolts all torqued down.

We stopped for a cheeky burger before calling it a day for other commitments. Just needs 5th gear fitting, the new seals and cups and selector I think. Then it can go back in. I'm not looking forward to lifting it again!

Hi thanks for the reply, I've got a spare ECU so will try that tomorrow. I'm going to check the wiring with a multi meter before I commit to plugging in my only spare.

I've already dropped the oil, so good shout.... it was significantly watered down with all the fuel going into it.

Hi,

Is it possible your main earth has become lose?
If so, the chances are your ECU has died:
When the main earth loosens, the car uses the ECU earth as the main and it fries it.
The main symptom for this is the injectors being stuck open.

First thing you need to do is drop your oil out and replace it with new, then fit a new ECU and try again.
If you successfully get your car to fire now, the diluted oil will kill your engine... ask me how I know!!

Engine & Gearbox / Won't stop priming

Hello,

So I'm putting my 1988 golf gti 8v back on the road, I recently passed its mot and returned home. It'd been off the road for around 5 years.

Couple of days go by and I reckon it'd be a god day for a blast. However it won't start. Nothing not even a click.

Tray the key a few times, try charging the battery and try the key again.

So I swap the starter for a spare one as im sure i saw it smoke a little and try again. With the replacement in this time the engine turns but the pump won't stop priming..... so much so that petrol starts coming down the exhaust having filled the cylinders.

I've changed the fuel pump, fuel regulator, vacum hose to regulator, injectors, pump relay, I've cleaned earth's point and connectors, I've made sure the fuel supply and return lines aren't blocked

But it still will not stop priming. Any ideas? Cheers
