A few weeks ago engine was overheating and damaged the cylinder gasket. I brought in someone to change gasket, after reassembled the engine comes on fires up and just about when it wants to run switches off again and will not start up again. But if you should try it after a hour or two, it fires up again and switches off. If you try immediately it wont fire up and drains battery charge.

Hello,

This could be a couple of different things, but let's start to see if it is your vehicle's Camshaft Position Sensor(CMP). Your vehicle's Powertrain Control Module(PCM) uses this signal to syncronize the firing of the fuel injectors. If this sensor is going bad it will act just as you have described, going out when it warms up, but will work when it;s cold. Without this signal your vehicle will not run. I have included in the diagrams down below testing for the harness connector of the CMP. In the diagrams below I have included a diagram of where the CMP is located on your vehicle. Please go through these guides and get back to us with what you are able to find out.

Thanks,
Alex
