Today we towed the airplane outside the hangar and started the engine. We started it on one coil pack, then the other coil pack and then both. Initially, we had fuel fittings that were loose and needed to be tightened. Once we had everyhting tightened the engine started. A couple of issues need to be addressed. First the RPM was reading to high and needs to be calibrated. The fuel pressure indicator and amp meter are not working. The ECU is not triggering the main fuel pump so we used the AUX pump. But key indicators like the CHT and Oil temp appear to be indicating properly. Next, we finished installing the AN4 bolts in the bottom attachments on the struts.
