Finished replacing the head gasket on my prerunner taco the other day. Probably the biggest mechanical undertaking as of yet and everything went smoothly ie no left over parts, wires ect. However iive spend the last 3 days trying to diagnose why it will not fire the spark plugs...
gone over the manual and checked the connections to:
crankshaft position sensor
cam shaft position sensor
check the resistance of both and both are ok
checked spark plugs and resistance on the ignition coils
and still no spark, wondering if anyone has any thoughts.,

Thanks

do the coils fire???
is there a signal from the IGNITER???

do you have fuel pressure??
