+1 On pulling your Fuel Inj fuse that it's the main fuse box and disconnecting your coils. The unburned fuel will wash down your cylinders and run down into your oil won't it if you do it enough? Either way, just good practice to do that when cranking on the motor alot.

Yeah- you could just pull the FUEL INJ fuse for now while you're working on the starter circuit, it won't affect that. It will need to be in however once you move on to things like getting the fuel pump to run. To so-called FUEL INJ fuse is the primary supply for the ECU.


edit: it just now clicked in my mind that you said the MAF connector melted. That's one of the locations that the white/red wire goes to. If that wire is shorting to something, it could very well be the cause of some of your problems. Also- that spot behind the coil pack where you said the jacket got singed on a bundle of wires. That bundle is the main engine harness. Lots of critical stuff in there.

I swear when I pushed the car into my garage after the fire I had normal power..all lights and what not. When I noticed it was after I disconnected a wire I had ran into my ignition power. This wire was hooked up to my destroyed Lc1 for power. Im wondering if I grounded that wire by accident when I was pulling everything out. Does that sound liek a possibility?

Joe Perez 09-28-2007 09:02 PM

At this point, anything is a possibility.

Shorting the LC1 wire while disassembling probably would not have hurt anything at that exact moment, assuming the key was off. This is of course assuming that you had the LC1 connected to a switched wire, and not one that was hot all the time. If any wires were subsequently left dangling however, then who knows.

Speculating much further isn't going to add anything new. It's time to start getting down & dirty with that multimeter, figuring out where power is and where it isn't. Once we've got some answers then we can start chewing on the data and speculate some more.

Shame you're all the way up in WA. As sick as it sounds, this is a problem I'd love to get my hands on.

you have no idea how much I wish you could...

piratetim 09-30-2007 02:53 PM

both my METER and ENGINE 15A fuses were blown. Thanks for the help again Joe

Joe Perez 09-30-2007 04:28 PM

So does that mean it's running? Or at least trying to run?

piratetim 09-30-2007 08:22 PM

I could start the car right now...but I cant drive it. No brake master yet or dipstick yet
