3 dummy lights on and motor has a hiccup
Hey guys, I'm stumped here and need a little help. I have a '96 F250 with a 7.3L powerstroke. The engine temp, water in fuel and fuel filter lights are all on together and the motor has a hiccup. Engine temp is good by the guage, I've drained the water separator several times and have installed a new fuel filter, but the lights are still on. Every now and then they will dim or even go off while driving but light up again if I let off the accellerator or go downhill. The motor's hiccup is a lot like when there is water in the separator. It jerks as if the fuel is off for about a half second, then drives on as usual, but it's happening a lot more frequent and if it happens when I'm stopped, it will kill the motor. I've put a bottle of SeaFoam in the tank hoping it might help the injectors or take care of any moisture issues, but the fuel is fresh. Like I said, draining the fuel/water separator has no affect. The fuel heater is disconnected from a while back when it shorted and caused the motor to cut off. Haven't had any issues with it in over a year since I disconnected that. I did have an injector that had to warm up before it would work right. Is there a chance this could be injector related? I've had injectors go out before but never with all of these dummy lights on. What would cause all 3 of these lights to come on at the same time? Especially when I'm sure none of the lights are on for the reasons they should be. Any and all help would be greatly appreciated. Thanks, Brad
