I have a 1995 landcruiser diesel wgn auto (hdt1) turbo and when deaccelerating up to a corner or to stop the engine will stall and sometimes be very hard to start. will crank over but not fire. sometimes i have to sit there and try a few times before it starts. It can also be hard to start first thing. (cold) but not every time. it is an intermittent problem. I have checked the fuel shut off and there is a feed to that at all times. It just feels like it has run out of fuel. I have checked the fuel supply and the return side for leaks or sucking air. any suggestions would be appreciated.
