Just went through the whole thread again, a work of art.

Sounds strong. Is it idling high?

marvgarr · Apr 12, 2015

Thanks everyone for the compliments. Leroy it is idling high I have not done the timing learn yet so the ect sensor is unplugged causing the high idle. I was going to learn it but then started to have starter problems again. I don't understand why I am having such a hard time with the starter. I got under again after it slipped and held the pinion gear out and it hardly touches the flywheel. I have the correct bolts and the rear starter bracket is on and tight. The flywheel is new and so is the starter.

Seems like I remember a thread about a similar issue and it had the wrong flywheel on it. IIRC it was from a gasser

That sounds familiar.

No gas flywheel on this engine. I have solved the starter problem for good. I investigated why it was slipping and found it was only engage on the very end of the teeth. I have the rear starter support and right bolts but still only touches the ends of the teeth. I had a buddy mill 1/8" of the mounting pad and bolted it up. It sounds like a stater now. It is quite and smooth, never skips a beat and doesn't sound like it is full of rocks. For anyone else that might have this problem have the mounting pad cut down. I do not recommend taking a grinder to it as you might not get it flat and cause more problems.

I did a little snooping in your thread, but may have missed it......just to be curious, what brand starter are you running?

marvgarr · Apr 16, 2015

I tried them all they were all the same. Right now it is a Delco.

Got correct ECM it now runs way better. I still need a new PMD.

What was wrong with the last ecm? Performance tune possibly?

Good to hear. What was the correct ecm?

marvgarr · May 10, 2015

Had to get a 95 ECM the old one was a 94.

Well I had a little problem with it so far I kept getting the code 35. When engine was running the PMD wires were hot and it shut down when they were moved. I got a new PMD so I know it was good the extension harness is one of the ones you buy for remote mounting the PMD. My fix was I ran 18ga high current wires from the fuel solenoid to the PMD. I shortened the command and feed back wires for the ECM and ran a 18ga power wire on its own fuse for the pmd. I do not have any codes now and it is a lot for responsive. If you have a remote harness check and see if its hot.

Update. The turbo decided to leak oil into the intake and exhaust. I overhauled the turbo and decided to ceramic coat the turbine and the heat shield to keep the heat out of the center section. I also made the battery tray. The battery is going under the right side of the bed. I will be using one group 78 900cca battery. I have tested this setup and have not had a problem even on the coldest day. Here are some pics the battery in the pics is not the one I will be using. I am using a side post battery to make it easy to remove the terminals.
