Don't bother with the fuses - if the work, they work.

Crank sensor tells the ECU that the crank has rotated, so it can generate spark timing, etc.   No signal = no spark.

on the 8v its under the oil filter.   Typical fault is burn't away wiring from hot engine & oil leaks etc.

Are you getting a spark on the king lead?

even though its a new coil pack, this one could also be knacked!! get a volt meter on the main lead from the pack to the dizzy and you will know if it works

and electrocute yourself in the process.... :-(  The coil pack will be putting out > 40,000 volts.

I don't think hospitallizing the OP will really help his car problem though.

hot start issue - often a failed / failing coolant temp sensor.

won't rev past 5000 = your machanic has messed up the ignition timing.

Usually best to start a new post for a new problem.
