Hey guys i need help bad i don't know what to doo ive been looking everywere and need some advice, Bassically the car wont start there's no lights coming on the ecu, its a straight gas research vl turbo, Ive put a whole new engine loom to see if that fixes it but nothing! even got a new alternator haha... it turns over just wont start, is there a fuse or anything for the computer?? ive tried different ecu's but nothing ive used a test light and none of the pins have power only one orange wire going to it.. Any help would be great before i sell the damn thing! Some original photos have not been recovered yet.

have you looked at the pink wire up under the dash at the ecu to fusebox plug. you say youve changed the engine wiring loom there are 2 types and if the differnt type is used to what was orig in it you need to join thw two pink wires on the loo m side of the plug. there is threads on here about it. i had this problem when i changed looms a few years ago.

http://65.98.23.226/~calais/showthread.php?t=176320 About one 3rd down there is a picture of the battery terminal and in the backround is a green plug with a redish wire loop that should be the fusible link that's giving you grief

Yus Thanks Ant man i know that plug i didnt know what it was for though!, would i need a new plug from the wreckers or just bypass it?

One from wreckers would be better as it's a fuse and needs to be able to melt in event of a short in the loom .. How ever if you know or can find out the rating of the fuse link you could probably by-pass it with an in-line fuse of the same rating
