Default Any experts out there?

I was trying to jump my 93 and now nothing happens when I turn the key to try to start it (no starter). The digital display is not working either, but the gauges and other displays seem to be OK. Is there anyway I can tell if and what the extent of the damage is to the ECM and digital display? Will the digital display work if the ECM is fried?

The display is controlled by the CCM under the dash. The ECM is under the hood just above the battery and controls the engine.

Sounds like you may have tripped your security system. This seems to be a common problem these days. Have you tried several times with the same results?

I tired looking into the security system (clifford concept 30), but I can't figure out how that would affect the digital display.

I know for a fact that when you try to start the car with a wrong combination key or anything that will upset the security from the car, it will not allow the car to be started for 7 to 10 minutes.

I lost my keys and worked with a locksmith to create a new one and then figure out what was the resistance of the key. Everytime we made a mistake the car would not engage the starter.
The security system detects this as an intrusion and will lock with a solenoid the starter. It will enable all systems after a period of about 7 minutes.
Maybe that is happening or the Clifford is affecting the factory security.

Good luck!

Is there a fusable link going to the starter?

Don't know a lot about the security features of my 90 l98, but I do know that when I went to start mine after the winter season, and the battery was DEAD- it would not start until I had fully charged the batt.

Hope this helps.

It does sound to me like you are in need of a new battery. What voltage are you showing?

BTW, there is no need to cross post . C4 Tech is where it's at for this sort of thing.
