Fuel Injected, 2015 AC XR550XT ATV (renamed the Alterra from 2016 on). 1300 miles.
I had written an earlier post concerning part of the problem, but a new one has arisen...
2 PROBLEMS:
Engine sputters & fails when throttle applied (even from idle and while in Neutral), and, now... Fuel pressure reads @ "0" despite clear line and operational fuel pump. Unit originally suffered fire in muffler - presumably due to engine driveability problem & resulting unburnt fuel... fuel pump ultimately died when starting repairs. Installed a new fuel pump as dealer advised it was the problem. Have now been chasing a proper fix for several months, as, while it generally starts fine, the engine will not take any sort of throttle - even from idle. Instead, it immediately starts to miss, backfire & die. From the beginning, the dealer claimed that a new genuine AC fuel pump was all that was needed. However, the replacement, non-AC fuel pump runs at 42 psi & works fine). NEW ISSUE: Unexpectedly, the first replacement pump stopped registering any fuel pressure (per in-line pressure gauge). This despite confirming both: (a) pump clearly pumping & (b) fuel line - all the way to the fuel injector - clear & delivering fuel. Tried a 2nd replacement pump which, initially, registered pressure (engine performance issues remained). But, when I tried to start it today, no fuel pressure again (and, therefore, apparently no fuel to injector). Again confirmed pump working and fuel line to injector clear & delivering fuel. Engine continues to start easily with starter fluid but, of course, stalls once fluid has burned off. While cleaning/replacing the fuel injector seems the next logical step, it strikes me that, were the injector plugged, I should still be seeing a psi reading on the installed, in-line gauge I've been using (not zero)!
Any ideas before I surrender this to the dealer and a B-I-G bill?
thanx, db
