[QUOTE="ionbeam, post: 1296381, member: 277"] Some of the following has been checked but I'll include it anyway: With the ignition key on - +12 volts on the Red/Black wires on the coils Verify - the Orange and Gray wires directly from the ECU to coils (no connectors) are not broken Verify - the plug caps are on and the plugs are good If all this checks out then the [COLOR=#0000cd]Crankshaft Position Sensor[/COLOR] and the timing wheel under the timing chain cover needs to be checked, the ECU uses this sensor to calculate spark timing. It isn't uncommon for wires to get pinched between the timing cover and the engine. [/QUOTE]
