Refurbished motor, new outdrive new distributor cap and rotor, new ignition module and coil, new spark plug wires.
I am wondering if anyone might have any suggestions that I can try. So here is my problem. All cylinders have spark (spark jumps over an inch), all cylinders have compression above 150, assuming all cylinders are getting fuel (I know #1 and #2 definitely are), when the engine is running and we pull the spark plug wire for #3 cylinder there is no change in the motor rpm (acts like a cylinder is running 10% or even a dead hole), when we replace the wire for #3 and pull #4 there is very little change in the rpm (maybe running at 25% of potential). Unlike #1 and #2 which have distinct rpm drops.
Also in order to start the engine, the coil has to be hot-wired from a 12v source to start. I am thinking it has something to do with the shift interrupt switch.
Any suggestions besides shooting it? :grumpy:
