Tried to restart we check the spark it has spark. Replaced the plugs and wires as they seemed old anyway. We have fuel and good pressure we have good injector pulse we checked with noid lights. we checked to make sure timing belt is rotating it is. Replaced the distributor due to failure about 6 months ago. the timing belt was done at 100K it has 189k On it now. my mechanic friend spent a few hours on it today and is still scratching his head. Was cruising at about 50 mph when it died. plugged in the scan guage to it and it was throwing no codes.
