Ford Repair: Explorer stalls when making right hand turn, fuel pressure gauge, power steering pump

Question
My explorer '93 4.0L will stall when I make a right hand turn.  The problem has worsened and now I have trouble starting engine in park mode.  Engine will turn over but not fire.  I have been able to start engine but sometimes it takes 5-20 starts.  Still stalls when making RHT.  I've changed MAF, TPS, and cleaned IAC.  This may be Power steering problem.  I cannot find the auxilliary power steering pump switch to replace.  Does '93 XLT not have this Aux.P/S Pump switch.  Left turns are no problem, except for the fact that it takes (3) lefts to equal (1) right.  Please Help!

Answer
Ike:

Odds point to fuel pump sender.  Install fuel pressure gauge on service port at intake manifold, tape gauge to outside of windshield facing in.  Drive and make right turns, fuel pressure should be in the 40 psi range. If fuel pressure drops only when turning right suspect fuel pump sender.

Hope this helps
