funny onion Posted June 8, 2015 Share Posted June 8, 2015 Basically went to try and fire up the GT I've been building and after testing a few things come to conclusion the ECU has no power. (Doesn't light up on the dash, no spark etc). Any suggestions on what to check? Thanks! Quote Link to post Share on other sites

funny onion Posted June 9, 2015 Author Share Posted June 9, 2015 Thanks a lot just got to the unit. I've downloaded the ECU pin out and the full wiring diagram so if I can't sort it I'll be setting fire to things shortly! Quote Link to post Share on other sites
5e colin Posted June 9, 2015 Share Posted June 9, 2015 hope you find it quick because electrics can do your fucking head in ha ha Quote Link to post Share on other sites
funny onion Posted June 9, 2015 Author Share Posted June 9, 2015 Sorted guys! Thanks so much for the help much appreciated, it was indeed the earth near the icv/injectors. I'd ran the loom underneath the inlet to tidy it up a bit and forgotten the earth 😳 haha. Just put it on and got the engine light on the dash woo never thought I'd be so happy to see that light on the dash hahahaThanks again! Quote Link to post Share on other sites
enots Posted June 9, 2015 Share Posted June 9, 2015 Crazy what a missing earth can/cant do haha i hadnt connected one for my headlights when it came to wiring them in turned the switch to test they worked and the engine started 😂 Quote Link to post Share on other sites
