Thank you for allowing me to assist you, my name is ***** ***** I will be happy to assist you with your concern today.

The first place I would start is checking the connector pins for bent and or broken pins, also checking for signal to crank sensor and back out to computer. This is generally either sensor, the wiring or computer, make sure to also check grounds as there may be a needed ground that is not connected. Make sure if there is a relearn that it has been preformed. There are only so many parts of that circuit so that shop should be able to diagnose to pinpoint the problem by checking sensors, wiring and connections to lead to what component is the problem as there is nothing else it can be.

Thank you!
