I just traded for a 6.5 diesel I was told that the only thing it needed was a fuel pump so that's been changed but still nothing it's acting like it has dead batteries so I totally disconnected them hooked one side up to a booster box and one side to my other truck via jumper cables but still nothing , any ideas ?

 

Ignition switch , bad conection on starter or ground, or starter. try jumping the selonoid with a screw driver.

 

1995 Chev 6.5 slow crank ,won't turn over at all , have completely disconnected the batteries and hooked up to my other trucks for power , starter seems to be fine also but no wait to start light comes on the dash anybody have any ideas ?????

 

Starter is fine , definitely not the switch will try jumping the solenoid , any other ideas ???

 

Will a hydro locked 6.5 expel fuel thru the tail pipe while cranking slowly ???

 

No need to make 2 threads to solve the same problems, you have to have 2 good batteries with at least 750 cranking amps to start these trucks half dead batteries will not do it even if the truck is in tip top running order, a 6.5 needs to be cranking at least 600 RPM's or more before it will fire up.

Make sure you clean all grounds bolted to the engine especially the one on the rear passenger side cylinder head.

 

Sorry about that

 

Update?
