I just recently bought a 94 Chevy 3500. It had been upgraded to a 6.5 dorsal turbo. This was a 7 year project and over 28k was put into this truck. I’ve got a stack of receipts given to me by the previos owner. The husband was sent away( prison) before the truck was complete. This is my first diesel truck so I’m just learning by reading blogs and YouTube. It turns over but just won’t start. Most of the components on this truck are new, any advice?
