Need to know which motor, if it's a zr6 I would lean toward coil pack?? If Excalibur try replacing cap and rotor. Either way I would check and clean the anti siphon valve

Is the issue you're describing what brought you to changing the pumps out? Curious what brought you to changing both pumps? Also, what PCM engine are we talking about here. I will assume however that we are dealing with fuel injected engine, And can't imagine that it has not given a check engine light.

It has spark and good power to the starter. If a coil was bad it would still run on the other cylinders?
not sure about the fuel pressure. |

2005 pcm super air 210. Changed both fuel pumps, low pressure and high, changed water seperator and filters x2, changed fuel lines.
boat runs great for 20 min then dies quickly. the engine will crank, batteries are new optima. fires slightly but sounds like its out of fuel. wait 15-20 and it will start right back up and run great for about 10 minutes until something gets hot again and dies again. |
