horrendous
Please help with this I am at my wits end trying to figure this out, I really need some pointers ideally from rubjonny
Many moons ago I followed this thread https://vwgolfmk1.org.uk/forum/index.php?page=topicview&id=modifications-and_2%2Fdx-to-abf-conversion to convert my wiring to run the ABF on its standard management using the CE1 fuse box.
All was well and this worked perfectly. A couple of months ago I had to remove the fuse box. I thought I labelled everything up correctly but in my heart of hearts feared the damn thing would probably never run again. My fears were correct, after refitting the car fires up and runs for a few seconds before dying. I suspect the immobiliser. Also I noted the fuel pump is not running so I bridged the relay but this made no difference to the firing then cutting out. I have vagcom and the port wired in but this no longer works since the fuse box came out, vagcom refuses to connect, I can try again and get the exact message if required.
I have gone back through the above thread and checked all wiring to the ecu everything seems correct. It should also be noted that with the vagcom lead plugged in the led on the lead flashes quickly for a few seconds when the ignition is turned on, but then goes out. I seem to remember it stayed on before but could be wrong.
I could use some help with this as my Golf is just sitting in the garage when it should be being driven. Thank you in advance Chris

try to connect to the immobiliser box as well, address 25. sometimes the internal changeover fails preventing you from talking to the ecu through it
does the isv vibrate ignition on?

Am I correct in saying the immob box has 2 grounds? If so one of those has popped off when I took the dash out.

Why not get rid of the immobiliser get it running then readdress the problem once it starts and runs ?sofarsogood said
I made the loom ages ago. I think I have figured out the issue.

immo removal is another way round it of course, but why spend the money having it done if you can just wire in the immo box. can even fit reader coil somewhere accessible and have it work as VW intended, help stop your car getting pinched or very basic way just remove key from reader when you park it.
you only need to wave chip at coil while you're starting it, once fired you can move it away

Re:
I agree with you 100% but if you take the immobiliser out of the equation the car starts and runs then back track to the problem does that make senserubjonny said
yes immo box has 2 earths which run to an ultrasonic welded joint then a chunky wire off to a ring terminal which earths to shell.

It was one of these that had popped off. As it happens I was also using this chunky wire as the earth for the diagnostics.
Thank you rubjonny
