Depending on how the TPS fails it will do different things. Mine failed to WOT so it triggered the fuel cut, so no fuel when cranking. If it fails closed it will start just fine.

From your logs though it doesn't look like its the TPS.

The adaptronic will only display from 10-20 AFR.

When mine was dieing at low speed I'd just stick it back in gear and pop the clutch. I was never sure if it would start on its own.

I had a hiccup then no start problem myself. Sounds similar to yours

Turned out to be a ever so slightly loose ribbon cable inside the MS box.

update... the car is starting now.

I pulled a COP out and shoved an old plug into it and grounded the threads to check for spark... didn't appear to jump an arc so I groped all the wires leading to the plugs for the COP triggers and as I got to the ECU, I swear I felt one of the stock ECU connections *click* into its seat.

I tried the key again and the car started... oddly the tach was dead and the idle was high. A few tries later, it started normally and everything worked.

I came in and checked the wiring harness pinout. the middle connector carries IAC, ignition, and tach signals. This makes some sense since the adaptronic was getting a normal tach signal as it is spliced before the stock ECU. The adaptronic is also not handling idle control.

I can only assume the no-spark was a fluke of my vision or grounding.

At least it wasn't something serious. Just something mysterious.


PS who changed my title?

Ha, same thing happened to me. My electrical system got very flaky after I had done an electrical system mod. At first I thought it was the new electronics, but it turns out one of the boomslang connectors that plugs into the stock ECU (parallel install) was not fully seated and making intermittent contact. Pushed it back in, problem gone.

I believe you claimed it was my homemade harness... which is probably fine. but it doesn't work so well when not attached to car.

I don't know what you're talking about but the problem was Yoko Ono for sure.

more ******* around yielded more information.

1. my obdii scanner usb connector broke and wasn't making contact so I couldn't check the MIL

2. after fixing #1, the MIL revealed itself to be a P1345 Cam Angle Sensor.

3. I started the car and let it idle for a while. After several minutes of normal idling, it started doing a weird "buh" and the idle would go briefly unsteady. It did this a few times (I was logging, nothing was obvious) and eventually crapped itself out.

4. I couldn't get it restarted, though it was behaving much more like it wasn't synching rather than just dead-dead.

5. Dug out one of my spare cam sensors (yeah, plural) and switched it in.

6. Started the car right up and the MIL was out--obviously it figured out there was a working cam sensor and corrected itself.

7. came inside to evaluate the original sensor:



You love my hack job, I know you do. Surprised it lasted as many years as it did.

The reason I never replaced it was because those god damn sensors are SO easy to break I figured it wasn't worth the effort.

So there you have it. zoom.
