Water in fuel system

[Kyleb]

Hey guys, I’m a big fan, and this website is really nice. I have not been here before.

Myself n some of my co workers are pretty good mechanics, not pros. I’m on a problem now that I just don’t know where to begin. I have many vehicles as I run a small service business. The vehicle I’m needing help here is a 2010 3/4 ton gmc savannah. 5.? motor.

What I believe happened is that the tire was cut intentionally, n water was poured into the fuel tank. The truck run good for about thirty minutes of stop n go driving. We filled it up with gas and soon after she give up. Happened in a span of two minutes. Engine started missing and shaking like vibrating. Then it died, cranked it back up and it died again and now will not fire off, just spins over. I’m real worried about rusting fuel injectors and pistons just not sure where to begin on how to bleed it down n pressurize the system with fresh fuel. I don’t even know how to prove it has water in it without dropping the fuel tank and empty it.
Any help?

I’m pretty positive there’s drain plug in fuel tank. That’s where you start.
Then you charge the battery overnight, to have good charge, pull plugs out, and keep cranking the engine, letting it spit out everything through the plug holes. Maybe pressure wash engine thereafter.
After nothing more comes out, reinstall plugs refill tank and you should be good to go. Donna, maybe toss in new inexpensive plugs. Just for kicks.
Tell the guy who drives that vehicle to stop irritating his GF. Or, messing with someone else’s wife.

The water in the fuel tank can come in many way. See this website to learn more about water condensation in the car fuel tank and gas station. http://www.ehow.com/how_6298865_eliminate-water-condensation-gas-tank.html
