My 1998 Dodge Van 350 (5.9L) stops running when put into gear. I replaced the Idle Air Control motor and when I put it in reverse it stays running but when I put it in neutral or Drive it dies immediately. If I hear correctly it sounds like the fuel pump works only in Park and Reverse. I checked the vac lines and can't find anything wrong. Any idea's ???

 

Got any chaffed wires that only short out when the engine rocks in the direction it does when going into drive?
