Blew a head gasket and got the head surfaced replace all gaskets new timing but now the car wont start. It gets fuel but it won't crank. We can force start it when hooking power to the starter but once the power is taken away it shuts off. No theft light is on and we've checked all sensors and fuses. Even checked the shifter. Went through the process to relearn my key as well. We are completely lost at this have no idea what to do next. If this helps it sat for about 5 months before we pulled the engine apart. Any ideas on what it could be or what we could do?
