There's Spark..and then there is SPARK. NB
PS: What year is your engine..?? just wonderin..
PPS: You said you grounded out the coil..does that mean you took the coil exit (center) WIRE and "touched" it to the block to see a spark...??
If thats the case..leave a sparkplug connected to a cylinder coil wire and ground the spark plug base.. to the block. Does the PLUG Arc..??
