hi guys, need a bit of help.

me and this other chap are doing an apprenticeship at a garage as mechanics, i have just started and he has been doing it for just over 6 months now. today 1 of the regular customers came in with this xr31 being towed, said that he had just bought a new car and asked if this xr3i was any use to the garage before he got it scrapped, so the garage had it and gave it to me and jamie to try and sort out. its a 1.6 convertible.

its got a fair few problems, doesnt pass the MOT for starters, brakes r fooked, 2 leaking shock absorbers, tyres are like slicks, buckled wheel, silicone and gaffa tape holding the side skirts and wide arches on, few more bits and pieces like that, and the main problem....it wont start!!!!

we have narrowed it down to being a wiring problem somewhere and today have had all the looms out of it and checked them all over and they are all fine, then started messing with the ecu and then we got confused with it.

1 of the feeds into the ecu had an earth and 3 didnt, point number 40 had an earth and 16, 20, and 60 didnt, we put all the dash back in and then for some reason they had an earth and have been fine since but there are a couple of things that we need to know.

is the pip signal supposed to go from the ecu or go to the ecu because at the moment there is no pip signal at all, anyone got any ideas why?

were not worried about anything else at the moment apart from getting it to start because if we cant do that then we might as well scrap it anyway. if me and jamie can get this car running and make it pass the MOT then the owner of the garage said that we can do what we like with it after that, the garage basically gave it to us because its something that they dont mind us completley stripping because it doesnt matter if it neva works again because it doesnt work in the first place.

any help would be much apprechiated,

thanx, ben.
