I have a truck that I bought knowing it was flooded over the dash. I've drained and replaced all the fluids. installed new spark plugs, cleaned the fuel injectors, replaced the fuel pump, starter, and crankshaft sensor. The engine turns over, its getting fuel and fire, but it will not start! I did not replace the pcm, but it seems to be ok. The service engine light comes on, but no codes. What else can I look for that may be causing no start?

 

It's getting an injector pulse/s?
