ok so i installed my tangerine racing tunnel and engine compartment lines no problem there, installed a 34R Optima Red-Top, a little big but oh well, went to turn it over, wouldnt turn over. i looked and coming off of the coil is a green wire attached to nothing, i think its a ground. where does this thing go.
any ideas on getting it started and where that ground needs to go. i would figure the engine case but i tried holding it there and pulled out a spark plug and hooked back to the wire to see if it would start and got nothing, i then grounded it to a bolt connecting the tin cover (i think?) to the head and the continuity tester said the circuit was ok so im guessing something has to be wrong with the ignition system, either the coil or distributor, which i THINK is newer and uses the magnetic thing to adjust dwell, which i loosly understand the concept of. also, could it just be the spark plug? it didnt look fouled or anything but i couldnt see a visable spark when having someone try to start the car and it wouldnt gap to the engine case either, so idk whats up im only 18 and a senior in high school so a lot of this is new to me, ive read about it in magazines but never this deep, nor got my hands dirty (i have now! (IMG:style_emoticons/default/beerchug.gif) ) i just wanna see the damn thing run, for only having 47,259 miles on the clock it shouldnt be too big of a deal to fix. i included a picture of what it looked like with just a basic clean too, no detailing or anything, not bad for being 38 (i think?) years old!) i trust the ppl on this site too, so if anybody want my phone number just shoot me a pm and id be more than happy to discuss it on the phone. THANKS IN ADVANCE. note: the green wire in the one pic is the one i grounded. it was just sticking up like in the picture before i grounded it |

Scott,
I would advise you to brinng a few with you, paul anders site on rennlist will tell you what ECU goes in what car....he has a full chart. For any of the cars running djet the fuel pump circuit is the same. The differences in the ECU is the hard coded air/fuel map. I would suggest that you do a complete test of the fuel pump wiring first and dont risk shorting out a decent ECU if the wire is rubbing or broken and shorted that is going to it. I would suggest that you do the tests a few posts above this one first. Then...pull the main plug off the ECU and use an ohm meter to test the whole FI wiring harness... There are lots of wierd issues when you have a broken wire or wires inside an FI harness...it will drive you mad. Rich |
