naa its like a coil and stuff you wire direct to the batt..i spose it bypasses imobilser and the ign switch prob a bit pricey for a one off job have you checked for voltage at the pump when it dies..will it restart after it dies or what
Aye, I took the pump out altogether, it was what I thought was wrong in the first place. Then I took the pump out of the scabby 530i BMW, which is an "all in-tank" arrangement - running it straight from a battery, dunked in a saucepan full of petrol, with 2 lengths of new fuel hose going straight to the fuel rail for feed/return. So I know it can't be the pump, filter or lines. Like I say, I'm fucking stumped! If swapping the Ign. switch and dizzy tomorrow don't work I think I've exhausted every possible reason I can think of why it won't run. I have a few Digi2 looms lying around, I suppose I could swap the whole loom. But I had been intending to convert it to a Digi 1 system anyway, which is more "self-contained". I have the Digi 1 ECU and everything I need to do it, but I'd really like to get it running on the original management before I start converting over.....
Checked the whole fusebox - all OK. The thing that has me beat is that it starts on the button, runs fine for a few seconds, then dies. Never seen anything like it before, and I've had a billion Mk2 Digi golfs.
so how easy does it start after it dies?? try running the fuel pump of a seperate 12v supply,like direct to the batt through a switch
It's already running straight from the battery, through a set of jump leads! After it dies, it'll start up again straight off, absolutely on the button. Then die again after a few seconds. If I hold the starter on, it'll fire up, run fine for a few seconds (overspeeding the starter) and then die, but every 2 or 3 seconds it'll fire a couple of times - but not actually start, unless I turn it off and start it from fresh.
hmmm does the digi's have them extra wires to the starter?? i know k jets have em,although im not sure what they do?? must be driving you nuts lol is the earths all ok..i know that's kill a digi ecu easily(ask me how i know)
Did the earths first, and the ECU is good - (tried it on my other one). Not sure about extra wires to the starter..... And yup, It's driving me round the fucking bend!
it might be worth a try asking on http://www.honestjohn.co.uk/forum or www.vwvortex.com ive had some advise of both of em before...might be worth starting a new one on here as people cant be arsed to read long threads
Aye, I was thinking of trying the Vortex - Honest John is a daft cunt though, are his forum users any better? Problem with the vortex is #1 I'm banned for life #2 Their cars always have o2 sensors so I think things are a bit different....... New thread might be a good idea... I'll try a couple of things tomorrow and see what happens, then report back!
e mail me something to copy n paste and i'll post on vortex for ya if its a prob theres a few decent guys on honest johns forum
Hello my favourite religeous icon. I have given this some more thought and I think it could well be the ignition switch. As I remeber digifant has a run and a cranking signal. Under cranking it doubles the duty cycle of the injectors. It may be that this is giving enough fuel for it to run for a few seconds but for some reason it's not running in the "run" position.
i was thinking like golden...it sounds like theres a cranking/start up signal of somekind maybe to ecu..that then looks for voltage to ensure its started and then switches over to running mode...does digi 1 and 2 have much in common?? i know some peeps that are whizz bang on g60's
Aha! In that case I'll swap the ign. switch before I try the dizzy - I didn't realise there was a different duty cycle in the "crank" position...... seems sensible now that you mention it. I was reading in one of the Bosch reference manuals last night that a lot of the "flapper-meter" type systems adjust the timing for the first four seconds of running, so it would seem about right that they would adjust fuelling as well.....
MY GOD this is getting me angry now...goddamn silly car LOL....Hope you have some luck mate. Sorry the imobiliser thing didnt work for ya
Lol.... cheers! Just swapped the dizzy AND the ignition switch, still no change....... I can't actually think of anything else to try, it might be time to put in a new engine loom and see if that changes anything......
