Re: 98 fuel pump ?

Problem corrected! Thanks everyone for the help..
Just though I would share what I found in replacing this pump in case some others might have the same trouble.
It was difficult getting the gas out of a completely full tank. You can't just put a siphon down the filler tube. It has a baffle in the tank that stops it from entering far enough to do any good. Take the filler connection apart and undo all supports for the filler and breather tube in the wheel well. Then remove the clamps that connect the two tubes to the tank. If the tank is full, you have to have the car slanted forward to keep the gas from just coming out. I had to lift the rear end over a foot and a half. Lifting also gave me plenty of room to work under the card. a small siphon can now be placed into the breather tube from under the cars and forced into the tank. Now the gas can be removed. 13 1/2 gallons
The only other hard part was getting the "duck bill" tube connections apart. You have to undo the tank straps to let the tank slide forward enough to be able to disconnect the rear duckbills(the forward ones are easily accessed). Using a disconnect tool really helped.
After the tank is off, undo the spring ring and the module will slide right out. At this point you can replace the entire sending module/gas pump for about $300-$350 or you can purchase a replacement pump only for about $70. (http://www.efuelpumps.com/) Ordered on Saturday, received on Monday!! If you purchased the pump only, you will need to take the pump and two hoses out of the module and replace them. Getting the old parts out was difficult at best. The old lines had to be cut off down 4 inches inside of the module were they connect. (very difficult!!) I used a dremell rotary tool with a tiny 1/4 inch saw blade to reach that far down and was very careful to only cut as deep as the thickness of the tubes (every thing is plastic). Their is probably a better way but that is what worked for me. clean this up immaculately. you don't want any partials to get in you injectors. Putting it back together was much easier. I heated the tubes a little and the slide on nicely. Clamps were provided to secure their fit.
Replace the module back in the tank and the tank back in the car , connect all tubing and wiring. Connect the filler tubes and your back in business.
One last bit of info. The new pump measured 39 ohms of resistance on the meter. The old (bad pump) measured over 275 ohms in one spot only(too much resistance to start the pump spinning from a stop. The old pump ended up having a dead spot on it's windings.
Thanks again to everyone.
