5.0L injection problems
I have a 2001, SeaRay 210 5.0 EFI, 351 hours. The vessel is in like new condition .
PROBLEM: Fuel is getting to the inlet on the back of the throttle body. but NOT through the fuel injectors and down the throttle body. I Borrowed a Injector pulsed diode light installed it on the fuel injector connectors crank the engine and there was no pulsing light, I have spark at the coil. I changed the coil out as a precautionary and still the injectors do not fire. The problem started after the battery died and the rain water filled up the engine compartment and flooded out the starter, I replaced the starter and cleaned all the wire connectors all the fuses were good, checked the wire harness to the ECM all seems good. could it possibly be the ignition module even though it is putting out spark the spark seems to be yellowish. The engine cranks and sparks but the injectors will not fire. I checked the ground connectors. There was some corrosion from being submersed. I removed the bolt and all the connectors cleaned and sprayed with corrosion block put back together with a new coil and still the injectors do not fire. Even though the module is putting out spark should I replaced that module, or is the problem elsewhere?
A local Mercruiser dealer had them scope (diagnose) the ECM and they found NO codes . It has Yellow-ish spark! Almost acting like the lanyard is "pulled", I flipped it up and down to see if it reset it, still no fuel. I have checked all the fuses both forward and aft. Circuit Breaker is functioning.
Thank you in advance for any ideas!!!
