Replaced my fuel pump & filter...after about an hour driving, the vehicle started struggling for power, surging. No lights came on...the more I accelerated or decreased speed, the worse it got. What is your suggestion?

I have a 98 Jimmy with no hot (or cool) air going to floor. Fan control, temp control, and A/C OK. Air switches between Defrost and Panel but not floor. I have verified vacuum at control switch and checked lines connecting switch to both air control diaphrams (red/blu to lower diaphram, yel/brn to upper) and verified vacuum changing with switch. The red/blue diaphram is definately moving, and I beleive the brn/yel one is also, when switch is changed (Def-Pnl-Flr) but I do not know the correct seq./position of the diaphrams in relation to the switch positions, so I cannot verify they are moving correctly. My only guess at this point is bad linkage or door -to- diaphram connection, but it is all hidden inside the ductwork... Any suggestions or detailed info on the diaphram positions would be appreciated.
