Bracket bolts were upgraded to a regular bolt that I would reach with a wrench and horn down on it, and loc-tite, btw.

I just went through a crazy episode like this on my 84.
Grounds were bad everywhere (the ground cable from battery and back of engine to chassis were both made of exposed copper wires and were heavily corroded). At first no fuel, we had to clip out a bunch of wires the PO had in there, even found a lamp cord, then it worked. After we got fuel, we had a no spark problem. Swapped the DME relay out and that worked. For this one, Id say sensors as well. If you all remeber when my black car died about a year ago, it was the sensors that killed it. I fixed it and never really reposted it. Sensors caused the injectors not to fire and no spark. Id rule those out first. I didnt have an oscilliscope, so I checked it with a multimeter. Each sensor should have a resistance of .999 which indicates the sensor is in good working conditon. The Oscilliscope should show if the sensor is gapped right. To gap the sensors, I used a .8mm thick washer and glued it to my dead sensor and put it in there, pressed the bracket down until it touched the flywheel then bolted it in position. Pulled the dead sensor, put the good sensors in and it fired right up. |
"I think this was just enough to loosen the very hard to reach and unloc-tited sensor bracket bolts (6mm allen head). Bracket vibrated down, sheared the ref. pin on the flywheel. Nobody told me that could happen. I tested everything 3 times. Someone finally clued me in to checking the heigt of the ref. pin. What ref. pin? Could be yer problem, tod. dumbass."
So your ref. sensor took out the trigger screw on the flywheel? Most likely the sensor is damaged too. Pull it out and check to see if the end is cracked open and spools of magnet-wire hanging out. This just reminded me of something. Did you put the figure-8 washer back in between the bracket and the speed-sensor? If you look closely at the bracket, the ref-sensor sits on a raised ledge on the bracket. The speed-sensor has no such ledge and sits about 3mm lower. The figure-8 spacer raises the ref-sensor about 3mm. This spacer ensures that both ends of the sensors are at the same depth. Without the spacer, the ref-sensor would sit way too highwhen the speed-sensor is at the correct spacing. So... if you don't have that figure-8 spacer under the speed-sensor, that's your problem. If you correctly set the gap on the speed-sensor to 0.8mm, then the ref-sensor would be about 3mm too high and get a weak signal. The spacer in question is #32 in this diagram: http://forums.rennlist.com/upload/sp...sorsspacer.gif |
Im sorry i havent responded lately I have been working graveyard shifts and only have one day off and the car is at my parents garage. but i did do some looking today and found out the rpm gauge does not move when i try to start it. also I tryed to jump thd dme relay and still nothing. I havent checked the speed-sensor yet... i do have a multi-meter and will try to check that as soon as i have time
Thanks for all the help everyone Shane |
