Really need help? Bought a 1997 Ford F 350 Ambulance to make into a work shop. Kept draining battery so a friend of my took it upon himself to tear out the wires to prevent batteries that were draining from the back of the ambulance but screwed up everything. Located a diesel mechanic which I paid to straighten out the mess that my friend caused. The mechanic came over and finally figured out what wires he cut and got the truck to crank but not turn over. Think the wires to fuel pump are not connected. Now the mechanic hasn't come back after numerous calls and text. The truck ran before all this happened. Can anyone help me? Need schematic so I can get the truck back into where it came off the line without the ambulance put on.
