I want to do a compression test on the 1992 300-E M103 engine. Were do I fine the fuse to the fuel pump, what number is it? is their any other items like coil disconnections that have to be done other than pulling all of the spark plugs.

Can I hook up a remote switch to the starter to crank the engine over? Were would connections be for this hook up?

Thank You
Bob Geco

Disconnect the crank sensor wire from the ignition module.
