Just wanted to thank the OP.
I had a similar issue with the crank being strong but the engine not turning over.
After I saw your fuse inquiry, I went to mine and discovered that my EFI 20A fuse was shot. Replaced it with the 20A radio one and the Landy just started.
Thanks for this thread and...
@melepley & @Espi SERE : Did any of you notice sagging from the front after the winch was installed.
The winch adds quite some weight up front and was curious if you've spotted or felt any difference in that regards.
