Strange noise while cranking.

Just got back from napa and he says they only list one number for all the starters for my car, nothing about auto trans. :(

Well I ordered that one listed for 1/91 and up auto cars, should have it tomorrow am and we will see what happens.

I let you know my experience with this issue on your ecmlink forum thread. The noise has come and gone a couple of times for me. I got rid of the noise and I never changed starters. I just changed the starter circuit harness (frayed and corroding ends on my original) and put in a new battery.

I have a friend with a 1g and his always had the grinding/scraping noise while cranking. Eventually his starter went bad and he had me throw in the new one. We were both excited to see if the new starter would cure the noise while cranking, it did not.

Have you checked for voltage drop on the starter circuit? Also measure the voltage drop across the solenoid. Voltage drop test the whole circuit, so don't forget the ground side (starter case back to neg terminal). And remember current has to be flowing for resistance to drop the voltage, so someone has to be cranking while your testing for voltage drop (excessive resistance). Rule of thumb is no more than .2v of drop per connection or .5v per cable.

Make sure the ground cable that goes into one of the trans bellhousing bolts is actually through one of the starter bolts.

Hmm, that's strange, but I've always had better luck with napa, OReilly's has had more issues with these types of parts.

yeah I saw your post on link, if my buddy stops by later I'll do the test and see what happens.
At this point I'm desperate to try anything, usually stuff like this is me fucking shit up, but I can't believe I haven't found the problem yet.

If your voltmeter has the MIN/MAX button you don't need a second person to crank, or if you have long enough leads you can watch the voltmeter while cranking also.

Tried that auto starter linked above with no luck, huge thanks to AJ/DSMghost for the help.

Just going to wait until i have time to pull the trans again in 2 weeks.

Is the starter just engaging for too long? I assume u have checked simple stuff like grounds etc. I suspect maybe the easy stuff like wires power ground and the hoodicky wire.

[turbotalon1g]

I tested all of those, and voltages while cranking.

When does the noise happen, as soon as you turn the key or as it's starting to fire over? Those pics on fb look rough. I did a quick Google search and found quite a few people with the same problem. http://www.dsmtuners.com/threads/97-gst-automatic-starter-grinding.473767/
