2002 7.3 Excursion 116 Fuse with new fuel bowl heater
First time posting with my new to me 2002 Excursion 7.3 4x4.
Just purchased last week, truck has 232,000 miles all stock with the exception of an SCT handheld Towing Tune applied by the previous owner. I am having my first issue and a few other observations that I am sure you all can help me out with.
First issue: 1) When i was pulling out of my court on Sunday the truck suddenly died and would not restart. Truck would crank but no dash lights. Googling pointed to fuse #116 and the many threads on the fuel bowl heater.
My fuse was indeed blown so I swapped in another 30 amp fuse and the truck fired right up no problem. I proceeded to pull back into the driveway figuring I need to diagnose this problem before driving again. However I cannot replicate the blown fuse again after cycling the ignition several times. I have not driven the truck again post incident.
I noticed the fuel bowl heater part outside of the fuel filter canister looked new and after going through the service records from the previous owner, i found the outside fuel bowl heater assembly was replaced in response to a fuel leak 6 months ago, P/N F81Z9J294BA , no mention of the actual heater element being replaced however.
In reading the other threads, it seemed the fuel bowl heater shorting out was blowing the fuse every time the ignition was turned on. Can the fuel bowl heater be an intermittent problem or should I be trouble shooting somewhere else on the engine / wiring?
Second issue / observation: 2) I noticed my waste gate solenoid was loose and i attempted to tighten up the small bolt on the front of the intake spider but it seems the bolt is bottoming out without completely tightening the solenoid bracket against the plenum. Is this an issue, or should i just shim it with a washer? (I included some photos)
Third issue / observation: 3) I also noticed the Red vacuum line was unplugged from the wastegate actuator and was just sitting on top of the actuator, i plugged it back in. Based on some of the other threads I read, this line is sometimes unplugged intentionally, however with my truck being stock, with the exception of the SCT tow tune, is there any reason to leave it unplugged? I was thinking it could have become separated or left unplugged accidentally. ( i included a photo of it plugged back in)
Thanks in advance
