I was advised to put SeaFoam in my dodge caravan to clean out any buildup. Now 3 days later it will not crank up and my husband says it sounds like the fuel line is stopped up. Does anyone here think this sounds familiar? Any ideas? I would appreciate any ideas you can offer.

If you put the seafoam in the tank, it may have loosend crude in the tank and lines and has clogged the fuel filter.

When you say the engine don't crank, you mean the starter doesn't turn the motor?
