Replace the coil and ensure that you get the correct coil voltage for the vehicle Coils come in to voltages Straight 12 volt coils that start and run on 12 volts and other that start on 12 volt and run on 7 volts. Check if it needs a resister with it.

Loud popping in the intake means that the unburnt gas exploding in intake.... Check cranks sensor and gear. Gear may dirty or even damage or BAD crank sensor the sensor provides reference for spark signal. So this may be your problem. Contact if you need more help. Thanks for using FIX YA

Coil resistance is not a good way to determine if the coil is good or bad. It might still need replacing. Check to see if your getting a pulse signal to the coil. You can do this by hooking a milivolt test light to the trigger wire and ground. If it doesn't flash as you crank the motor, check out your pickup coil in the distributor. Some of them you can change. Some you have to replace the entire distributor. Sometimes oil will leak into the distributors on certain models which use an optical pickup. If this is the case, change the seal to fix the oil leak and GENTLY clean the optical sensor and photo wheel.

did you change the main coil and coil wire?if so then check the ing resistor and then the computor box

I have problem with coil not working. In the morning,car with not start, but if I run a wire from battery to (+) to coil (+) will start. the rest of day no problem,car will start. but next morning same problem no spark from coil. c
The "Checking For Spark'' test should be performed prior to this test.
This is a basic test of the ignition system that
systematically examines the battery, the coil, the engine controller,
and its wiring harness and connections; the most likely culprits in a
no-start condition at this stage. Fabricate this special jumper with a 0.33 MF capacitor in-line to test the ignition coil

The ignition must be turned OFF prior
to unplugging the engine controller connector. If it is not, electrical
surging could occur causing damage to the unit or other electrical
components in the vehicle.
This procedure requires an ohmmeter to test the coil
packs for primary and secondary resistance (specifications are given
for an ambient temperature of 70-80°F/21-27°C). The two coil packs contain five independent coils, which fire paired cylinders (shown numbered)
