DailyDrifter: Cam sensor was replaced with new unit. Can't read scanmaster if car doesn't run...
dailydrifter:
1. I don't think my scanmaster is "reading" with key on engine off... I'll need to double check. (IIRC it, the scanamster, would fire up with key on and then turn off since engine was not running)--- Bear in mind my other "known working" ECM was swapped in and there was no change---
2. To clarify, when you say CALPAK do you mean ECM, the Chip, or something else? (there are no other devices in this car)
3. Grounds are all secure
4. I previously pulled and checked all the fuses for ECM, IGN, etc... (all good to go.)
5. This car is nearly all original and untouched- absolutely zero hacking to any of the wires...
Blazer406: I don't think the scanmaster was reading with the key on/engine off... I need to double check... (It crossed my mind that this was incorrect but figured I was imagining things since I rarely drive these cars and never have any issues). Can't try any cam sensor tricks since I can't get it to run...
TurboDave: Dead ECM is ruled out as I have swapped a known working one in. I looked at your attachment (thanks btw,), and I only see one 12v wire (A6 pnk/blk) which if I'm not mistaken is the same color as the one I tested at the injector harness AND at the Ignition module-- (Both shows 11.6v) I assume power runs to the ECM first and is then disseminated to the various sensors? Or vice versa.... Can't see both ends of pnk/blk wire having power and the ECM one not having it first... Of course I could be mistaken...
As for the second 12v input, maybe I'm blind or staring right at it but I cannot tell from the attached chart which one that is. Can you clarify?
Have you tried this yet? Is the bolt to the cam sensor tight? If it moved injector timing can be off..Yep, loosen the hold down on the cam sensor and give it a little turn. You'll know if your going the right way when you try and start.
Mine hit... popped... farted.... maybe it cranked... I can't remember.... but it did alot better when I re-set it on #1 compression stroke instead of exhaust stroke. It was a very noticible difference.....at least on my car.Ya, but a car will start and run with the cam sensor 180 out. Ask me how I know this.
