Strange no start issue on LH2.2 turbo -1988 Posted by Notnoel [Email] (#23) [Profile/Gallery] (more from Notnoel) on Wed, 25 Apr 2018 20:05:55 Members do not see ads below this line. - Help Keep This Site Online - Signup |
This is has me stumped. Just discovered a very odd thing (I think). The body of my AMM is negatively charged even though it is not obviously grounded to the chassis. I was disconnecting the battery and the wrench touched it an sparks flew. This doesn't seem right!-
Car has been running great for many months - no issues. Last weekend I replaced the flywheel and clutch as part of getting ready for a T5.5 conversion. After I got done, the car wouldn't start - it has no spark. I figured that I must have cracked a 30-year old wire or something so I went about checking all of the continuity between the distributor , the coil, and the ignition amplifier - it is all fine. I checked the coil, and ran most of the checks for the Hall sensor on page 340-6 and 340-7 of Bentley. I've got power to to the Hall sensor, ignition amplifier, and coil, and coil resistances are fine. Ididn't do step 4. Hall sensor out put or step 7. ignition control switching function because I didn't have anyone to help me this evening.
I swapped in different known good ignition amplifier, and ECU, and distributor, but still no spark. Anybody got any ideas?
I am tempted to just say screw it and go ahead with the T5 conversion and rip all of that out of there and replace it, but I am a little concerned about putting all of that new hardware in when I know something is wrong with the car (grounding issue at AMM as described above). I don't want to burn up brand new parts and once the T% goes in the local shop will be useless (mechanic doesn't like to work on modified cars).
Really needing the Saabnet braintrust here! TIA
