I recently bought a 97 ram 1500 the guy i bought it from was in the process of putting in another motor and hacked the harness up got a new one in changed out computer but i have no power to coil when key is in start position anyone have any ideas what to do

 

Moving this to the second gen ram forums for ya.

Welcome to DF!

Coil will only have power for about three seconds after you turn the key to on, unless the PCM sees the engine turning.

What year truck did you get the harness/PCM from?

 

Its the original harness and pcm

 

See if you get spark while cranking.

Check the crank position sensor. They tend to take a beating if not removed when swapping engines/transmissions. (and then they stop working.....)

 

Where is it located

 

Behind the passenger side head. It bolts down on the bellhousing.

 

K thx
