Espar D4 issues

[geoffm70]

hello, anybody use a D4 Espar Airtronic cabin heater? I'm having issues, even after totally cleaning it all up, new screens, working fuel pump, everything seems perfect. Replace the ECU for $600 and the "f-in" thing still starts up, gets warm and before it goes into boost mode, shuts down.

won't start, I meant to say.

killed the Espar. Bought a Russian knock-off for less than half and Espar.
