At this point you will need a scantool such as the DRBIII I use here at the dealership to see if the PCM says "Ok to start" or "Denied". If it has a gray headed key this can not be bypassed..

I hope this helps,

So the engine stays running for a minute then stalls? Will it start right back up and run another minute? What codes are setting?

Customer: replied 11 months ago.
it will over and over again
Customer: replied 11 months ago.
its just like someone turns off the key

i was thinkingmaybe automatic shut down
Customer: replied 11 months ago.
its not giving any code on dash
Expert:  -Brad- replied 11 months ago.

Are you loosing spark or fuel when it stalls? If it's spark you will need a scantool to see if the PCM is telling it to shut off. What year was the Grand Cherokee that you used the engine from?

Customer: replied 11 months ago.
1999 jeep and i use a 99 computer and tied everything else myself,its just like someone turns the motor off it will do it at te same time everytime

a friend of mine has a scantool maybei can hook it up then crank it and see what code it gives when it dies
Expert:  -Brad- replied 11 months ago.

Did you use the 1999 wiring harness and PCM in the 2000?

Customer: replied 11 months ago.
just from computer to dodge harness and then to fuse box everything is operating good and works the fuel pmp is pumping its getting fire because it cranks but its shuting down for some reason
Customer: replied 11 months ago.
i know this is a weird question for you , are not the norm, but was oping it was security and could bypass
Expert:  -Brad- replied 11 months ago.

The only way your going to determine the issue is to monitor the PCM with a scantool.. It will show what's going on when it stalls..
