I have a kawi FD791D fuel injected v twin on a scag mower. It was working fine one day and the next nothing. It pops out the intake and backfires out the exhaust while cranking but never starts up, sounds like it wants to. Checked fuel pressure from the fuel pump by plugging the line with my finger, and it seemed to be making decent pressure, replaced the fuel filter, checked spark has spark on both cyls, compression is good. What commonly goes wrong on these things? Any ideas. This thing has all sorts of sensors and crap on it what ones should i check, crank sensors, fuel pressure sensors? Not too sure on these fuel injected engines?
