You test an ignition coil by checking the resistance with an ohm meter. The resistance values should be something like, Primary winding .3 to 1 ohms, Secondary winding 8,000 to 11,500 ohms.
You will need a timing light, set it at 10 degrees BTD
Change ignition.
1,8,5,3,6,5,7,2
The primary resistance is= 0.5 to 0.7 ohms. The secondary resistance is = 20 to 30 K ohms. Tom L.
for damage to the ignition sight tube
Its possible your new keys don't have a matching resistance value to the car. There are 15 different resistance values, and your local dealership can look up what the value should be if you can provide proof of ownership.
try checking the ignition circuit on the side of the distributor.
take it to the dealer and wait for the bill $$$$$$$$$$.
You can check the ignition module (coil) with a digital volt/ohm meter for a start. Check the primary and secondary circuits resistance and go from there. You can also check the spark plug wires resistance with the same meter.
REMOVAL PROCEDURE Remove the engine cover. Disconnect the spark plug wires at the ignition coils. Disconnect the ignition coil harness connector. Remove the ignition coil mounting bolts. Remove the ignition coil. INSTALLATION PROCEDURE Install the ignition coil to the bracket. Install the ignition coil mounting bolts. NOTE: Refer to Fastener Notice in Service Precautions. Tighten Tighten the ignition coil mounting bolts to 8 N.m (71 lb in) . Connect the ignition coil harness connector. Connect the spark plug wires at the ignition coils. Install the engine cover.
The generic number given for wire resistance is 1000 ohms per foot
