So this is happening in the truck in my sig, 2000 7.3L powerstroke. so when i first bought the truck i was told that the glow plugs were bad and needed replaced so i had to keep the truck plugged in. well replaced the glow plugs last fall and found that one of the pins on the uvch hardness was blown out. so i replaced this about a month ago. so i have not been plugging the truck in but driving it everyday. i was gone for a couple days a week ago and when and tried to start he truck and it would not start. what is going on? i dont really know what to do now and need this truck to be dependiable for work now. is this the ipr?
