specs for coil:

Primary voltage with starter actuated:

pins 124+ 2 at N3/10=200-350Volts

resistance of coil: primary- pins 124+110(N3/10) with ignition off =.9-1.6ohms
secondary-pins 4a+4b=6-8.5kohms

ignition voltage: 8-20kilo volts with started actuated and kv sensor connector connected to each of the coil

another thing to keep in mind is fuel injectors that are leaking, not operating, have a bad spray pattern or that are not spraying at the same time. to do that remove the fuel distributor rail along with injectors as a complete assembly, place a cookie sheet underneath and turn ignition on but dont start. Make sure they spray, if they drip they are leaking
