I have a PCM 5.7 inboard and i have a problem that the engine only starts after cranking for almost a minute before it will start when hot.
I have checked the fuel pressure and replaced the pumps.
Replaced the coil, ignition module and plug wires.
No dtc's are present
Compression is good.
Replaced the coolant temp sensor.
The engine starts instantly when cold.
The engine must cool down for about 3 hours befor it will start again.
Has anyone ever heard of such a problem.
