Q: What should i check next?

asked by on

Changed the battery, clutch sensor, ignition switch is good, all relays work. If the car starts it runs for1 minute then turns off. After it turns off, I have to pull the negative off and reset system. Alternator is good, starter seems fine. What should I do next?

My car has a manual transmission.

Hello. It sounds as if the issue you are experiencing could be computer related. I would recommend taking your vehicle to a professional with a high tech scan tool in order to check your powertrain control module for proper function. If your powertrain control module is not up to par I would recommend having it replaced with a new one. Be sure to have this replacement done professionally as a reprogramming may be necessary after the replacement. A technician from YourMechanic can come to your home or office to inspect why your car starts then dies and make the necessary repairs.
