Hi everyone. I am new here but I really enjoy the wealth of info from you all. I have an 86 f 250 6.9 idi. I bought this truck and it is my first diesel. I had alot of trouble getting it to start cold. Replaced all glow plugs. This truck has been modified with manual push button switch for plugs. I rehooked the original wiring and the controller only stayed on about one to two seconds after truck sat for a week. Today i connected bypass wire and original glow plug wiring together at once, the system is now operating as it should without using pushbutton. Anyone have any idea what happened here? I also want to mention that after sitting for a week it takes a while for fuel to be primed to cylinders, still not sure what is going on here. Any help would be appreciated.
