I can't start my 1990 BMW K1

I have not been able to start my K1. I replaced the plugs, they are getting spark. Cleaned the ground connections and just cleaned the ignition that is fitted to outside of the battery back. The fuel pump is working, but all I?m getting is some back-fire. Any recommendations on where I should look and what must be tested? What are some of the common problems with starting a K1?

No spark from coil to distrubuter


Disconnect the ignition coil output wire at the distributor cap.
Connect a spark plug to the end of the ignition coil output wire which you just disconnected.
Connect a ground wire to the threaded portion of the spark plug.
Disconnect the ignition coil ground wire from the negative terminal on the coil (Green Wire).
Connect one end of a ground wire to the ignition coil negative terminal.
Turn the ignition switch to the ON position.
Tap the other end of the ignition coil ground wire jumper on an good grounding point (for example the battery negative terminal) and look for sparks at the spark plug that correspond to the frequency of your tapping of the ground wire.
If you have a good spark at the spark plug, the ignition coil is good.
If you don't get a good spark, check for approximately 12 VDC from the coil positive terminal (black wire) to ground with the ignition switch in the ON position. You should also get approximately 12 VDC from the coil negative terminal (Green wire) to ground
Ignition Coil Resistance Check

In addition to the test above, you may elect to perform an ignition coil resistance check as confirmation of the coil's condition.

Check the ignition coil primary coil resistance by connecting an ohmmeter between the positive (Black wire) and negative (Green wire) terminals on the coil. The resistance should be 0.4 to 0.6 ohms.
Check the ignition coil secondary coil resistance by connecting an ohmmeter between the coil output terminal and the ignition coil negative terminal. The resistance should be 5000 to 7200 ohms.

You may have a bad coil or bad ground or wire connection

1983 Capri RS WONT START it is getting spark to the plugs and fuel turns over fine just wont start


Points or electronic ignition? Corroborator, or fuel injection? Was the car sitting idol for a long period of time, say, 6 months to more than 1 year? With a car that old, I would start with replacing spark plug and ignition wiring. Have you checked the spark plugs? Make sure they're cleaned and gaped. If corroded, replace them.

95 saturn gas on the spark plugs


It is normal for them to show gas-continued cranking of the engine keeps putting more gas in the cylinders.
Oil is getting in there from worn engine parts-piston rings or worn valve guides or valve stem seals. If enough oil gets on the plug, it will inhibit sparking- known as "oil fouling". Oil fouled plugs can be cleaned and reused. The near-prohibitive cost of repairing the worn engine parts with an engine rebuild may make you want to remove the plugs and clean them as often as necessary to keep them from misfiring. However, if it is just worn valve stem seals on those two cylinders, a shop could replace the seals without having to take the cylinder head off. The cost for that job would be some less. You might want an estimate on that. The seals are a rubber composite and quite cheap. A little tricky, but it can be done without pulling the head off.
Now that you have cleaned those two plugs and put them all back in, the gas will have evaporated. So if it does not want to start, you need to check for spark to verify the ignition system is working. The easiest way and to avoid a shock is to buy a cheap spark tester, pull off a plug wire from a plug and hook to tester. The tester is then clipped to a metal bracket or bolt as a ground. Then have someone crank the engine over, while you watch the tester for a spark-a strong blue spark, not yellow or orange, will verify ignition system is good. If no spark exists, test all cylinders. One or two with no spark could be a bad coil on the coil pack. But if no spark on any, the ignition system will have to be diagnosed. Good luck./

The igniter interprets signals of time and position from the distributor, fits the efi ecu with information and then the ecu gets back to igniter to tell it when to fire specific cylinder, we used to have problems with the distributors and also igniters.

What do i set the spark plugs to before i install them.


Check the plugs for deposits and wear. If they are not going to be replaced, clean the plugs thoroughly. Remember that any kind of deposit will decrease the efficiency of the plug. Plugs can be cleaned on a spark plug cleaning machine, which can sometimes be found in service stations, or you can do an acceptable job of cleaning with a stiff brush. If the plugs are cleaned, the electrodes must be filed flat. Use an ignition points file, not an emery board or the like, which will leave deposits. The electrodes must be filed perfectly flat with sharp edges; rounded edges reduce the spark plug voltage by as much as 50%.

Check spark plug gap before installation. The ground electrode (the L-shaped one connected to the body of the plug) must be parallel to the center electrode and the specified size wire gauge (please refer to the Specifications chart under the hood for details) must pass between the electrodes with a slight drag.
Hope this helps.

I have 2002 Pontiac Grand Am and I cleaned out the spark plugs and replaced them. The car still only cranks and will not turn over. Any help you provide will be greatly appreciated.


Possible causes:
Ignition coil bad
Electronic ignition module bad
Coil wire to the ignition module bad
All of the above.

Pull out one plug and ground it to the engine. Have someone crank the engine as you watch for a spark. No spark- see above. If there is spark the the problem lies in fuel/air/compression.

1992, 4.9L f150 has no spark. I have a new distributor, computer, ecc, coil, wires, plugs, checked fuses, cleaned connectors, new relays, have 12v at the coil, good ground and no spark at all? help.


Help,
I have a 92 F-150 XLT with a 5.0. The ignition switch block burned up so I replaced it. Now it will not get spark when I crank it over, but when I crank it and let off of the key, I get one spark jump from the coil; to the distributer. (I have a spark tester I placed on the cap to the wire) I have replaced the coil and the ignition module that is on the fender attached to the brain, I have replaced the ignition cylinder and key (It was acting up) and I took the dash apart to see the wire harness to ensure there was no burnt wires. (The wire connection to the ignition block is not damaged from when the switch burned.
Does anyone know if there is a part that tends to go bad when the ignition block burns up??
Help, Thanks, Todd

How to replace sparl plugs on a Jeep Cherokee?


Hello, I hope this info helps...(subytech1)...REMOVAL
In this engine, each individual spark plug is located under each ignition coil.

  1. Prior to removing spark plug, spray compressed air around base ofignition coil at cylinder head. This will help prevent foreign materialfrom entering combustion chamber.
  2. On this engine each individual ignition coil must be removedto gain access to each spark plug. Refer to Ignition CoilRemoval/Installation.
  3. Check condition of coil O-ring and replace as necessary.
  1. Inspect spark plug condition. Refer to Spark Plug Conditions.
CLEANING
Theplugs may be cleaned using commercially available spark plug cleaningequipment. After cleaning, file center electrode flat with a smallpoint file or jewelers file before adjusting gap.

CAUTION: Never use a motorized wire wheel brush to clean sparkplugs. Metallic deposits will remain on spark plug insulator and willcause plug misfire.

ADJUSTMENT

Setting Spark Plug Gap - Typical
Check spark plug gap with a gap gauge tool. If the gap is not correct,adjust it by bending ground electrode. Never attempt to adjust gap bybending center electrode.

INSTALLATION

CAUTION: This engine is equipped with copper core groundelectrode spark plugs. They must be replaced with the same type/numberspark plug as the original. If another spark plug is substituted,pre-ignition will result.

Special care should be taken when installing spark plugs into cylinderhead spark plug wells. Be sure plugs do not drop into plug wells asground straps may be bent resulting in a change in plug gap, orelectrodes can be damaged.

Always tighten spark plugs to specified torque. Over tightening cancause distortion resulting in a change in spark plug gap or a crackedporcelain insulator.

  1. Start spark plug into cylinder head by hand to avoid cross threading.
  2. Tighten spark plugs to 27 Nm (20 ft. lbs.) torque.
  3. Before installing coil(s), check condition of coil O-ring andreplace as necessary. To aid in coil installation, apply silicone tocoil O-ring.
  4. Install ignition coil(s). Refer to Ignition Coil Removal/Installation.

Changing spark plugs


Changing the spark plugs on a 1997 Ford Expedition 5.4L engine takes patience. Remember to start this project on a cold engine! I started on the passenger side by locating the Coil over iginition coils and cleaned out all the old dirt using some compressed air. Then I had to disconnect the electrical connections to both the Coil over ignition coils and the passenger side fuel injectors. Once you remove the small bolt which holds the ignition coil in place, use your compressed air again to blow out the spark plug hole. After that, you will need a 5/8" swivel spark plug socket and various length extensions to remove the spark plugs. Take your time because there is not much room for your hands. Before installing the new plug, check the gap and use clean engine oil on the new threads. Tighten the new spark plug and reinstall the coil over ignition coil. Reconnect the electrical connection to both the ignition coil and the fuel injector. Continue these steps with all eight spark plugs. You will find the ones on the drivers side are difficult because of the fuel rail gets in your way. Have patience and use swivel extensions to work around the tight spaces. When you are done, you will have saved lots of money! Don't forget to replace your air filter, fuel filter, and pcv valve to complete your tune up.
