hey guys. i have been trying to fix my truck for a while now, and it seems to be baffling most everyone i ask. My p38 keeps doing this thing every couple weeks, where when i start it, it will turn over fine but won't stay running for more than a second. It happened four times now, and everytime it just works again after a few days, weeks, etc. Everyone on the forum told me it was probably a fuel problem, aka pump, filter, relays etc. This is what i thought too. But, it seems that the only thing that makes the truck turn on is the mechanic. All 4 times now, i replaced parts and checked wires, just to be let down. Whenever i give up, i take it to my mechanic(no Land Rover experience) and he merely jump starts it and it turns on. When i mess with it, i start it and start it, until the battery dies, and no matter how many times i jump it, it will start up but never turn on. Maybe the truck just doesn't like me.. Pleaase someone help.. I don't know what this could be. thanks so much.
