My VW Jetta SE cranks but doesn’t start. My son was messing with the fuses trying to fix the back light. The next few days my car wouldn’t start. I took it to a foreign car mechanic and after a few days on his lot he asked me what happened as if someone did something to the car.He also said the computer is not communicating with the engine. Any suggestions I will call him back tomorrow.
My only suggestion is that the next time your car needs repair, don’t ask your son to do it.
My suggestion is to tell the mechanic your son has been messing with it.
Oh, and get ready for a larger repair bill! Fixing someone else’s screw-ups can be really time consuming… and time is money.
