current state of affairs
Getting extraordinarily frustrated with the car. About a month ago I pulled the engine harness off the car and rewired the ECU side of it, getting rid of all the splices and generally cleaning things up pretty well.
Got everything reattached last night, and the car persists in doing the same thing it had before the rewire: Starting strong, revving to ~1500 rpm for a second or two, then completely dying. Every possible course of investigation into the causes of this has been pursued–sensors, wiring, ECU, connectors… Everything.
I know it’s going to be something simple. It can’t be complicated and not change at all as I plug and unplug various peripherals searching for the culprit.
It had been be worth it to drive; that’s all I have to say.
I’m not as bummed out as you might imagine, though. If nothing else I was encouraged by the fact that I ripped the whole harness off the car, rewired and cleaned up every wire leading to the ECU, and I didn’t screw up the car more than it was before. This is good.
I hooked the battery charger up to it earlier and sat in the driver’s seat, listening to the stereo and shifting aimlessly, left hand holding the steering wheel. Between bouts of frustration with the harness, I needed some re-motivation.

1JZ-GTE. Stock a 280 hp mill, assuming I have decent compression from the ~25K mi. engine (and happy turbos), with the 3″ exhaust, intake, and boost bumped up to 10 psi, I should be over 300 comfortably. For a while. Assuming I get this running by February (please God), I’ll have some hard numbers after a dyno day.
Poor man’s BMW 850i. Apologies for the lamppost in the middle of the photo. The rims are loaners–they’re from the engine’s donor car and the owner of said car wants them back. I couldn’t resist putting them on, though. They’re only 16×7 (stock size), but it’s definitely the style I want, albeit much larger (18×9-10). All in good time. I just want to drive it… Wish me luck.
Update 12/30/03: It RUNS! Thanks for all the help, guys. It wasn’t getting fuel, as most of you suspected. After poking around for a little bit I did the one thing I hadn’t done yesterday that I knew to do–jumpered the fuel pump from the diagnostic block on the harness. It fired right up and didn’t die! There are still a few more quirks to work out, but this is HUGE, and I’m elated.
