fuel pump pressure
My '93 has been dying on the road.Got a code 16 and 36 which indicates bad opti-spark.I was checking the fuel system with pressure gage.When I turn on the key (no start)the pressure goes to 47# then falls back to 40#.Is this typical or is the pump bad?If I start it the pressure stays at 40#.Anyone had this happen?
Thanks for any help.
