Hi, thanks for the donation. When it refuses to start, is the security lite on? Sometimes when battery voltage is lost, it goes into theft lock. On this vehicle, I believe, no injector pulse. When it refuses to start, leave the key on, watch for the serurity lite to go off, may take about ten minutes. Then try to start.

If you don't think it is the security system, I'd still have to check for injector pulse.
