My 79 928 has been running great, then yesterday it backfired once and just quit. Could not get it started again. I towed it back to the house and started troubleshooting. I have verified that I am getting spark to the plugs and I disconnected one of the injector lines and I am getting fuel delivery to the injectors. When I crank on it, it almost starts, but just sputters for a few secs and then quits. I can't imagine it being anything with the timing, but I'm stuck. Any idea on what my next troubleshooting step should be?
