A wire could have been dislodged or disconnected beneath the dash. To get an indirect indication of this, check for spark at the spark plugs. If no spark, there is probably a primary side ignition system circuit that was "touched" under the dash when you did this work. On the other hand, of course there could be an unrelated fault that has nothing to do (was not caused) with the work you performed. In that event, if you want the required diagnostic steps performed by a certified Mechanic, dispatched by YourMechanic right to your location, please request a no start diagnostic and the mechanic will find the fault and get your car running. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
