Keyswitch has to close the relay as soon as it is turned on.

Expert:  Curtis B. replied 1 year ago.

Is the relay closing?

Expert:  Curtis B. replied 1 year ago.

If relay is closing, wire from relay to solenoid may have bad connection.

Expert:  Curtis B. replied 1 year ago.

Solenoid has two internal coils, one is for pulling it in , and the other is to hold it. Hold is always powered from relay, the other is only powered in start.

Yah checked all that it ended up being the safety switch under the seat was not working. Now for some reason my fuel flow is restricted. Trackor will run for about 5 min than shut down. When I look at the fuel filter it is almost empty. I think something is holding the fuel back from the tank to the filter. Or do you think there is something else going on?

Is there a vent on the tank or is it through the cap? Thinking it might be building up a vacuum in the tank and stopping flow.

Tank is vented through the cap.

Maybe the tank has debris in it? Plugging the outlet hose?
