Hey I just did a full rebuild and now when trying to start it up, with a fresh battery, it turns over but super slow. Jumping doesn't help. Could it be a problem with the motor itself? Or starter?

How are your grounds? Especially the one between the transmission and body?

I just went through the same thing when I changed my clutch. I reconncted the grounding strap but evidently didn't have a good ground. I disconnected the strap and took my dremmel tool and cleaned everything up reconnected the strap and it started like a champ.

I cleaned up my grounds and I'm getting a little over 12 volts at the starter. I pulled the plugs and it turns over faster but not nearly fast enough. Also with the plugs out and tranny in gear I can't push the car, even with two guys.
Thanks again -Adam |

If jumping , a good battery, grounds rechecked, and still doesn't help cranking speed, you must have a problem with some of the turning gear. by that I mean clutch, pressure plate, trans, fan on the front on with too long of a bolt, something that would cause the flywheel to turn slowly. You probably should start checking clearances now before you damage something.
