Jim,

When it happened a month ago I put 3 bottles of dry gas in the tank after the trooper had sat for 3 days and a few days later it started ok. Would water in the gas cause the trooper to set the check engine codes???? Would water in the gas cause it to act like this??? This all started this time right after I toped off the tank with gas. It had 1/2 tank of gas at the time and I filed up with gas the day before the breakdown. What would you suggest that I put in the tank???? I have been using regular "gas treatment" when I fill up ever since I had trouble a month ago. Would you suggest something stronger to use in the tank???? How long would I need to let the trooper sit to be able to start it normally again???

Back in the Oct 2009 I had an issue with the trooper not running and I changed out the fuel pump. It turned out to be the electrical connection going to the fuel pump instead. When I changed out the pump a few years back a few bolts snaped off in the flange that holds the pump assembly in place. I switched out the phillips head bolts with hex head bolts at that time. When I changed out the pump in Oct I didn't get an airtight seal to the rubber gasket at the top of the tank when I put the assembly back in. I was having trouble getting one of the bolts started so I left off a small washer, that I was using with the bolt to make sure that it was super tight, so that I was able to get the bolt started. The bolt is in tight and the assembly isn't loose or anything like that. I noticed that after I changed the pump back in Oct 2009 that I didn't get the hiss that I am supposed to get when I take the gas cap off to fill the tank. Also on the first fill up after the pump change in Oct I did overfill the tank a little and had a little gas come out of the top of the tank in stead of the filler neck. That is how I believe that I don't have an airtight seal with the tank. Would this allow water to get into the tank?? It kinda sucks not having the 4x4 during a snowstorm. This is our only vehicle at the moment. My other vehicle is an 87 trooper which is down for repair with a compression issue.

Thanks for your help.

Mike
