And injector so I took it to the shop now They say the engine wiring harness needs to be replaced because it's not sending a signal to cylinder 2

After playing with the ignition a few seconds it will finally start. Just happens every so often and seems to be tied in with radio and seat controls. Electrical?

I ws toldthe Audio Board needs to be Rebuilt or Replaced. 3 Week project! Who can work on this?

Repair shop has changed both Low coast brake solienoid and valve harness, problem returned after 5 days of use. Repair shop owner seems clueless, all he wants is more money to find problem. What is the correct fix for this problem?
