check your oil....
reset your ecu (unplug battery for about 5-10 minutes)
check your ecu (where did you get it from, which program?)
check the wires on your conversion harness
trouble shoot

if their was a prob with your solenoid, it would not have worked with the other ecu. i think u may need a new chip. what program is on the ecu?
