When you fix something that lights the "Check Engine" light you need to clear the computer. You do this by undoing the NEG battery cable for 10 minutes and then reconnecting it. Otherwise the old warning will show for 25-40 startups before the old warning cycles out.

If you did clear the computer and still get the warning you need to check the other things that the coils hook up to. These would be the plug wires and the sparkplugs. Another possibility is you were off on the layout of #1 cylinder and firing pattern, then changed out the wrong coil.

How to replace gmc1990 pickup coil


I assume this is the HEI coil. If not let me know and I can help further.
Instructions
    • 1 Put your safety first. Engage your emergency or parking brake. Also, disconnect the negative battery cable from the Chevy Corvette's battery.
    • 2 Make the ignition system visible. On older models, you may need to remove the plenum extension for the intake manifold using a screwdriver or wrench. For newer models, remove the cover for the fuel rail.
    • 3 Look for additional parts that you need to remove. For HEI systems, you need to access the distributor through the cap. Other systems use an ignition coil harness connector.
    • 4 Disconnect the secondary wires, or spark plug wires, from the ignition coil. Tag each wire with masking tape, so you know which terminal to reconnect the wire to. If you connect the wrong wires to the terminals, your Chevy Corvette won't start.
    • 5 Detach the ignition coil mounting bolts and remove the ignition coil. The amount and type of bolts vary depending on the part number for the Corvette ignition coil. You may also need to remove the ignition coil arc seal.
    • 6 Clean the distributor cap with a soft cloth. Now is a good time to replace the seal, if needed. Insert your new ignition coil and secure it in place. As you reassemble, use a Torque wrench to tighten the mounting bolts or screws to 13 inch pounds (1.5 Nm) of torque.
    • 7 Reassemble the rest of the parts and reconnect your battery. Start the Chevy Corvette to ensure the repair worked.

How to Test and Replace Ignition Coil on BMW 3 Series


The following procedures apply for BMW 3 series (6-cylinders engine) 1992 - 1998 model years. To Test and Replace the Ignition Coil, do the following:
  1. Remove plastic engine covers from top of engine by prying off nut covers and removing cover mounting nuts.
  2. Disconnect harness connector from coil. Connect multimeter between terminal 15 (+) in connector and ground. (use a digital multimeter for the following test). See Fig.1. below BMW 3 series coil harness
  3. Turn ignition on and check for battery voltage. If battery voltage is not present, check wire between terminal 15 and ignition switch. The wiring to terminal 15 (+) of the coil (via the ignition switch) is not fuse protected. Use care when testing this circuit.
  4. Turn ignition off.
  5. Use a multimeter to test coil primary resistance at coil terminals. (primary coil terminals: 1 (-) and 15 (+), primary coil resistance: 0.4-0 .8 ohms; secondary coil terminal and resistance: NA).
  6. Remove coil and inspect coil housing for hairline cracks or leaking casting material . A leaky ignition coil may indicate a faulty engine control module (ECM). Check ECM before installing a new coil.
  7. When replacing ignition coils, ensure that the replacement coil(s) are from the same manufacturer containing the same part code numbers. If individual coils with the correct specifications are not available, all coils should be replaced.

I have a 2001 toyota fourrunner showing computer codes p-0300 & p-0304. What are these codes for?


The P0300 is a random multiple misfire code, the P0304 is specific to the number 4 cylinder, a common problem for this code is a igniter/coil malfunction on the #4 cylinder, each cylinder has it's own coil, what you can do is to remove the #4 coil pack(it's the middle one on the driver's side) and switch it with coil #2 which is the first one on the driver's side, clear the codes and drive it if the code now shows P0302 replace the coil.

I have a 63 chevy corvette 327/340 hp, 4 spd. When recently taking the car out of storage I charged the battery and attempted to start the car. It cranked but no start. There is gas that gets to the carb....


Check for positive voltage at coil terminal from ignition. Also check point gap and replace condenser. Let us know if that doesn't do it or if you have more questions.

Replaced clogged 2002 grand am inline fuel filter. Engine turnes over and attempts to start but will not crank. The engine is receiving plenty of fuel. Could the computer- ized engine timing be off? If so,...


try drying out the plugs possibly flooded,, if its flooded try drying the plugs out and let the engine sit to dry the cylinders out.. the timing never goes out on computerized ignition, replace the plugs and ignition wires and test the coil resistances. 3 coils test between each coil where the ignition wires go KEY OFF, they should be 5 to 6 thousand ohms each if not replace the bad coil.. also did you pinch the fuel line check it for kinks ...good luck
