Been trying to get this NA 86 z31 running for awhile now, I've got 37 psi to the fuel rail with the key on and car off, spark at all 6 plugs, 13+ volts at the battery, and ecu reads code 44. Motor has good compression in all 6 cylinders (150+). When you crank the car, it often seems to skip a beat while cranking, in sync with dimming of the interior lights. Car does not start with starting fluid into the throttle body, or maf unplugged. Been trying to get this thing running for awhile now and beginning to lose hope. I'm looking towards ignition timing to be the culprit right now but unsure how to verify that the car is actually in time (or out of time). Not a mechanic by any means so anyone has any pointers please lmk! Thank you
