Engine has a tendancy to trip or burn out ignition & fuel pump relay switches.Sometimes unhooking the + battery cable resets and the engine will start.Then again the relay is replaced and it will start or the 10amp fuse is removed and plugged back it and it starts. So confusing. It will run all day (sluggish at times)but usually will not turn over after setting for a few hours.Is it possible the electric fuel pump is faulty?O2 sensors?The fuel injection system appears to be getting gas.Fuel/water seperator has been changed.

My 1st Guess would be to Check Each,+ Every Ground connection..........<br />And,<br />That means Removing,+ Cleaning,+ Reinstalling.......<br />Not just Looking to see that they're There.......

Thanks Bondo.Would it possibly be an alternator or voltage regulator giving off too many volts?The meter reads 18 amps but after running settles in around 13-14 amps.
