Default Help needed 91 Jeep no start

Checking to see if you guys have any idea what to do next...

No codes
Fuel is good
spark is good
Relays are all new under hood
Starter has been replaced
Injectors are only 6000 miles old
Ignition is MSD

She cranks slow on jumper cables to a diesel
Sounds like she almost wants to start but no go.

Any ideas what to look at next.

This all started 4 weeks ago when she just shutdown while driving, I founc a broken wire leading to the SS Blaster coil (repaired that), Fuel pump was rally weak, so I replaced that, the starter selonid tested bad, so I replaced that as well.

At this point, I am not sure what else to look at, perhaps the computer?

thanks for your assistance
