I recently did a electronic fuel pump upgrade on my 7.3 IDI I took off the starter and the alternator and clean them up I put a block off plate where I removed the mechanical pump I got a relay with fuse combo got everything wired up with the alternator back on and put the starter back in and when I went to crank it over it I gave the truck a little jolt seem like a pretty strong pull actually because I had also bought new batteries. I tried it a few more times and same stuff wouldn't continue to turn over just the jolt. I took it out inspected it did a bench test seem to be working put it back in and same thing. Does anybody know if we have to shim these cuz there was no shims on it when I took it out I'm not quite sure why it's not doing what it's supposed to do everything that I removed I cleaned up contact points and everything before I put back together so if anything I would think that it'd be working better not worse. Especially with the new batteries.
