I have an Evinrude e70 PL4 year 1999 outboard motor. And it won't fire up. It is just firing up with 3 spark plugs, one plug hole must be open to starting the engine. If I insert all the spark plugs into the engine, the engine will not fire up (second video).
How to fix this, what to check?

The motor is not working with 4 spark plugs:

Spark plugs are new. Spark is on all plugs (when I pout out the spark and try to fire up). The pump is working. Fuel injectors are clean.
I have a check engine alarm with code MAP sensor 2 (second video), but I think this is not the reason. I have this MAP sensor 2 problem earlier and it was working.
Any ideas of what to do?
