The fuse is on the over voltage protection relay.
You have a MAS module/many relays, this controls the fuel pumps.
The relays are located in the module compartment.

When you put the key in to start, have someone on the rear right side, to listen for pump noise.
They will run for only a few seconds, BZZZT that's it, lol, and stop.

Crank sensor plug is located on the left fender side, is connected to the EZL.
Make sure that is connected properly.
