Yes there is, but not sure if it has a reset button or different type.What did dealer say & where did they say it was?

no wait to start light is a good indication that you need to check you glowplug relay and harness. Make sure you have 12V in and out of the relay. Also if you can check to see if you have good continuity to ground through your glow plugs. This is kind of hard to do on this engine, sometimes it is OK just to check the AMP draw for the leff and right group of wires. Do this by putting an AMP clamp around all 4 wires to the left and right bank. Wait about 45 sec. for the relay to click off (if it clicked on) and then record the amps right before the relay turns off. Let me know what the amp draw is and I can check it against the spec sheet. Se you amp clamp above 100 amps, it might start around 60A and end up around 36A if I remember correctly.

sounds like a bad ground or short to the signal wire what you can do is trace the wires from the tank to the bulk head connector to check for brakes in the wire but first do a ohm test on the three wires with the key off there is resistance between the wire you have a short if not check for brake or corroded connections

SOURCE: intermittent no start, very strange, very confusing

Sounds like fuel pump going out. I was told by a friend that the pump can get stuck and that by knocking on the fuel tank or by attempting to start that it can kick the pump out of the bad spot and it will start. But it is a sign that it needs to be replaced.

Check the choke in the carb, might stay stuck in the open position when engine cools down. After the engine is cold, check and see if the choke is closed, if not close it by hand, and see if that works.
