Question about 1994 GMC Jimmy
Have a 1994 GMC S-15 Jimmy with CPI have replaced plug wires, fuel filter, TPS, MAP sensor and EGR valve. Starts great one time, then immediately trying to start it again will hit one time, then just turn and wont fire. Holding the gas pedal down, it will fire and sounds like it is running on half the cylinders. After a minute it will idle normally. After warming up some it will sometimes surge and hesitate when opening the throttle.
Did you do a fuel pressure test? if you havent do it its cheep an at least you can elimanate that. if thats not an issue, then there is only two other things crank sensor, and if there is one cam sensor.
