Ok, its a 1990 SI. Its an OBD1 b18b with a 00'ITR head and a obd0 distributor/injectors and a PR3. First start, ran but really rough, back-firing, wouldn't idle, etc... Moved dizzy as far forward as i could, smoothed out a little, still ran like ass, but it would idle. I double check timing marks, All line up....however, at TDC on #1 the dizzy rotor was between #1 and #4, so i backed the intake cam up one tooth. Now...i have nothing but a continuously blinking LED on my PR3, no fire at all! Getting fuel though. I just replaced the coil pack, cap, rotor, wires and plugs....still no dice. I do not have a knock sensor hooked up. Any help would be appreciated, i have been trying to get this thing up and going for a few weeks, keep hitting stoopid little snags like this.
