Crank and no start.

I took my 97 honda CR-V to Walters Auto because it had an intermittent crank and not start engine issue. I left the car for him to diagnose and find the problem. At the end of the day he told me the car was fixed for a balance of close to $400.00. Without contacting me first he installed a aftermarket distributor. After several months the vehicle started having the crank and not start issue again. I diagnose the vehicle myself and fount it to have a bad relay in the alarm system that caused the starting issue. I related this info to Walter and asked if he still had my old distributor and he stated that he used it as core for the new distributor. After checking with the Honda dealership and several auto parts stores. They all declined that when you purchase a new distributor they require you to give them the old one for core. Walter specialized in fixing Honda and Acura vehicles. He did not get a code saying that any component was faulty on my vehicle, but he change out my distributor which was perfectly fine. The car wouldn't start because the relay would expand when it got hot which opened the circuit. I was taken for needless repair and still had the start issue. BEWARE!!! Do not pay for repairs you did not authorize and sign for.
