MJ Vr6 79 Posted November 18, 2015 Report Share Posted November 18, 2015 ECU sends signal to crank to fire up.From what your saying it can possibly be the Crank mate. Link to post Share on other sites
Mk3highline 287 Posted November 18, 2015 Author Report Share Posted November 18, 2015 Cheers just had someone else crank it over and there is a faint sparkTook fuel pump out to test and that is working well heard it spin I think now it may be a bad earth but it's chucking it down so will have to wait Link to post Share on other sites

Mk3highline 287 Posted November 25, 2015 Author Report Share Posted November 25, 2015 Just tested relay and that's clicking when tested with 12v out of the carPlugged it back in and turned key and can't feel it click,Could it be the ignition switch??What activates the fuel pump relay? I'm going to try put a direct live to the pump once I'v got some new clips for fuel lines Link to post Share on other sites
Mk3highline 287 Posted November 25, 2015 Author Report Share Posted November 25, 2015 (edited) Put direct live on the fuel pump And that's working now Now I've charged the battery, put a direct live to the fuel pump and cranked it over with no joyTaken a plug out and it was dryChecked for a spark and only get one at first turn of key, I held it turning over to make a few revolution and no spark besides one at first turn so will have to try a crank sensorSee how that goes Edited November 25, 2015 by Mk3highline Link to post Share on other sites

fog-allan 30 Posted March 2, 2017 Report Share Posted March 2, 2017 I had similar issue with my vr after battery had been disconnected for few months, turned out immobiliser (selca im.22 or something) had "forgotten" the key fob and so was activating fuel/spark cut off when I tried to start it. Simple but worth a look if you haven't already done so... Link to post Share on other sites
Mk3highline 287 Posted March 6, 2017 Author Report Share Posted March 6, 2017 Immobiliser was taken off when I had the map doneGot the new ecu tried and it's firing up now but new ecu needs immobiliser taking offSo ecu was at fault fog-allan 1 Link to post Share on other sites
