Drain fuel bowl .. tested refills no problem. Did fuse test no blown fuses... WTS comes on when ign is on... oil pressure gauge moves half way up after 4 spins of engine. Did buzz kill test on injectors and all passed. I have no smoke from tail pipe .. I’m getting 12v from battery and going to IPR ... tach moves while trying to start.
