Iím looking for the symptoms of a if your pump going out on a Thor ace 30.2 2015
1. Takes multiple Cranks before it will start
2. Turn key to the on position can hear fuel pump engage , Engine turns over, will not start . On third attempt to crank fuel pump will not engage And motor cranks .
3. On certain instances motor lurching at high RPM
First things first then. Read the history codes, if you don't have access to a reader places like autozone do it for free. Even though it feels like a fuel problem, might be something like the crank position sensor not sensing the cranking. The codes will point you in the right direction.
