Hello!

I have the above-referenced truck. It's set up as a fuel delivery truck. We are having the following problem:

The truck starts, idles, runs, and drives pretty much perfectly. The problem starts when we engage the PTO to run the pump when making a fuel delivery. Within a few minutes of starting a delivery, there is a repeated beeping while the red engine light blinks, afterwhich the engine stalls. The truck readily re-starts without a hitch. Depending on the length of duration of the delivery, this can happen two or three times. When left running without the PTO engaged, the truck idles smoothly until you turn it off with the key.

There are NO indicator lights illuminated on the dashboard.

Please advise. Thank you in advance for your response(s).

Thanks for replying pop.

Here's the deal. The pump works off of a pressure valve-type throttle directly on the pump. there is an air switch for high or low speed. This does not affect the idle speed. I dont have a hand throttle/choke in the cab.
