any help would be great

 

I was driving home on the freeway once, going 115 up a ramp(no one was anywhere near, it was a toll road) and my car stalled and wouldn't start. I checked for codes and got a 22, I remembered that had something to do with the timing circuit so I checked the distributor connections and one had fallen off of the ignition coil. Check for that.

 

swapped out module,,,wires ok,,,and didnt help

 

have you by chance checked your fuses? you've probably got a fuse for Inj. or Ecm-a or ecm-b. start there.

 

turned out when i hit the bump my wire connecter on my ecm fell out i guess it was not plugged all the way in,,,runs again
