I'm working on my mom's 2005 S60 2.4-liter non-turbo. How it started, I my mom had me install a non-Volvo water pump, timing belt, tensioner and belt pulley around May 2018. In November 2021 the water pump locked up and slipped the timing belt, causing the valve and piston to make contact. Well, I tore the engine down and took the head to a well-known shop, Scroggins Machine in Houston, TX. For whatever reason it displays a crank sensor, camshaft sensor, and brake pedal signal. On first start will start up and run for 20 seconds and die. Cycle the key it will start and run 30 seconds, then die, like you turned the key off. If you do not cycle the key, it will not re-start. I have today replaced the camshaft sender, the crankshaft sender and brake switch. And the crankshaft senor wiring. Any ideas to what it could be?
