June 26, 2011 - I swapped out the fuel pump yesterday.
There were none of the hoped-for obvious problem signs - no big chunks of gas tank stuff clogging the inlet, no damaged wiring. Nuts. A drive today in hot (95F) weather unearthed no problems with the fuel system, but it drove fine almost every time before. So the jury's still out. I hate it when things are inconclusive like this.
We did find one definite problem, though. The car is very well ventilated, quite livable even in our hot climate. But when Janel drove it in open-toed shoes, she discovered that increased speed pushes some air through the heater core and directly on to her feet. Now, the heater core is still running coolant through it as I wasn't sure when I hooked things up if the LS engine could do without that particular circuit. Apparently it can, and so I am under orders to fix that particular problem quickly before her feet melt. I'll have to see if I can find the old heater valve again.
Other than the hot toes, she did bond with the car. Especially when she was trying to merge and wasn't sure if she had enough room. I told her to punch it, she'd have enough room. Yes indeed she did. She laughed and started looking for opportunities to open the throttle.
