What Would YOU Do?

Now i'm not an expert but If It was mine i would remove all the spark plugs and turn the engine over by hand (with a wrench) if it spins free, I would bump the starter and see how it acts. Trying to figure out if the starter is malfunctioning or if its in the motor. I would expect the gas to run down past the rings easily enough but......if you care about the motor which i'm sure you do once that issue is resolved I would change the oil to get the gas out of there. Gas in the oil shouldn't make it act like that. Just ruin the viscosity and protection the oil gives.

That seems like a good plan. Removing the spark plugs and turning the engine on this truck is a real chore, and my back is acting up again. Will try bumping the starter again (did not work yesterday), then try turning the engine with the plugs in (they are really hard to remove).

The 29 year old engine only has 53k on it, so I'd like to keep it around for a few more years, LOL.

If you cant get the plugs out...turn the engine by hand...backwards..

It sounds like the cylinders filled with raw gas and have hydraulic locked up....

If you have a wrecking yard close by, try buying a second hand TBI unit and installing it...so many times I have witnessed rebuilt units fail and fill engines with gas...

Of course you will need to change the oil again and filter...

Good luck.

Thanks for the suggestions. I see you are in NC where all the flooding is going on. I'd never even heard of hydrolock before. Will try turning engine backwards tomorrow!

Am wondering why the system is not relieving fuel pressure and how to fix that. Why didn't GM put a relief valve on the fuel rail that I could stick a hose on??? Cannot believe how much harder this truck is to work on than my old C10...
