Re: carrier 2500a
There's a one way valve between the filter and the pump(brass with a direction arrow), these have a habit of packing up. You can try blowing it out with compressed air or fit a new piece of pipe bypassing it.
If you open the jetstart and it runs for a bit it means its using the fuel return as its feed.

Re: carrier 2500a
Is the fuel filter plugged up. It will run with a plugged up filter if the jet start is open.

Re: carrier 2500a
how many hours have the three done ?
do you change the oil regular ? As old oil tends to gum up the fuel head.
If they've done a heap of hours try adjusting the valve clearances.
