You need to check and make sure you have fuel pressure, then check for spark at ignition, if those check out then check for pulse width at the injectors. That basically is the electrical signal which tells injectors to spray fuel. Use what is called a Noid light on injector pulse width check. that will eliminate all possibilities other than internal issues with engine. I.E. broken cam, broken timing components, obviously if all I mentioned checks out then run compression test. Good Luck

If all the coils are giving spark now,then you moat likely have gas fouled plugs now,so change them out with new ones,all 8 of them.If you do not have spark on all plug wires,pull the timing belt cover,and align the cam shaft and the cam,to see if the belt has jumped.If It hasn`t,replace the crankshaft sensor.
