Hello to All. Wish this were not my first post as a new F250 owner.

The "Wait to Start" light does come on and go off after about 15-20 seconds but I can't get my 7.3 to start in the morning without it being plugged in. It will just blow unburned fuel white smoke.

Soon as it does start it runs smooth.

I replaced the Glow Plug Relay yesterday and the plastic housing was cracked so I had hoped that was the problem but its not.

I just bought this truck and don't have a personal history to offer except its got 138K miles and is bone stock from the family of an older gemtleman that passed away.

Thanks for any assistance.

 

I hope I have not broke forum etiquette or anything. I do want to assure everyone I did a fair bit of searching before posting and thats what led me to this forum.

Can anyone confirm that if the issue is with a blown Fuse #22 or #30 (both 30amp) then the "Wait to Start" light does NOT come on?

Can I check resistance of the glow plugs without pulling the VC's? Would that be your next move?

I did purchase this Glow Plug Relay from NAPA and not Ford. The reason is that where I live in AK is very far from a Ford dealer but there are always NAPA stores nearby to warranty their parts. This relay did come with a 36-month warranty compared to Ford Parts counter offering 24-month.

Thanks
