Almost a year after finding metal shavings in my oil, we finally finished installing the new engine. However, when we ran it for the first time today, it only would run with the boost pump on. The engine driven pump doesn't seem to be working, but it was run on the test cell before shipping, so I can't imagine it has now failed, although that is one possibility. Here are the details:
ECI IOX-360-A4B1N 180 HP with ECI injection, built by Western Skyways.
Andair duplex selector with return lines to both tanks
Vans standard boost pump
- Runs great with the boost pump on
- Mixture adjustment doesn't change the performance when the boost pump is on, even at idle cut-off
- Engine quits once boost pump is turned off
- With return line disconnected and boost pump on, runs fine with fuel flowing out of the return line
- Will not run with fuel line run directly to a fuel source, bypassing the boost pump.
Any ideas?
