Why does 99 honda cive ex have no ignition spark?


There is no definitive test for it the ICM, or igniter. If you are positive that the coil is good and it has power at the black/yellow wire, confirm that it is hot at the igniter. Make sure all 4 connecters on the igniter are tight, they should not pull off easily. With the cap off, you should check for spark directly from the coil to ground. Rotors fail too. If everything checks out, and still no spark, the next step is replacing the igniter. Check prices at Honda, sometimes they are the same or cheaper than aftermarket.

89 Comanche 4.0 inline 6cyl no power to pump and now no spark as well?


I'll try to help you, John.
For spark: If your spark plugs, spark plug wires, dist. cap, and rotor are good, check the coil. Take off the negative battery cable. Use an ohmmeter and check resistance between the coil primary positive terminal and the frame of the coil-ohmmeter should show infinite resistance, if not, replace coil. Put ohmmeter positive lead on coil primary positive terminal, and ohmmeter negative lead on coil primary negative terminal-resistance should be zero or nearly zero, if not, replace coil. Connect ohmmeter negative lead to the negative primary terminal and ohmmeter positive lead to the high voltage terminal of the coil. Ohmmeter should not show infinite resistance, if it does, replace coil.
If coil is good (or has been swapped), check that coil primary has power to it with key on. If it does, and no spark, the problem could be the ignition module or the pickup coil. The ignition module should be mounted with the ignition coil. The pickup coil is inside the distributor-this pickup coil is what tells the computer (ecu) the crankshaft position, so is critical for spark timing.

For the pump: the fuel pump relay is in the power distribution box under the hood. When the ignition switch's run wire energizes the relay's coil, power is sent to the pump. You could check for a signal on the pump wire at the tank, with the engine cranking Should be a steady signal then. If not, pull the relay out to check that the power feed for the pump is still there. The power to the relay comes from Fuse link G, a 20 amp rated green fuse link. It is hot at all times, so check for a power signal on one of the relay terminals with key off. One terminal should have power. If not, check fuse link G. If it does have power, put relay back in and have someone cycle the key-relay should click-may feel or hear it. If nothing, try a different relay. If relay was good, but no power to pump, pull relay and check terminals that relay plugs into: with key held in crank, two terminals at relay should have power-the power feed from fuse link G, and now the ignition switch signal to the relay coil side. If all checks out, probably a bad pump. If you checked for power at the tank with the engine cranking, and did have power, that is for sure a pump that needs replacing.
Good luck.

2000 silverado 1500 no spark


check ignition fuse to coil and check see if power getting to coil if yes ignition coil or ignition module faulty.if no power getting to coil and ignition module more likely you have blowed ignition fuse or faulty wiring from ignition fuse box terminal to the ignition coil and module.

We have a 1993 Mitsubishi Eclipse 1.8 and we replaced the interior, dash, and instrument cluster. Everything was fine except the instrument panel would not light up. Connections were checked and a few were...


Found this wiring diagram. Voltage for the coil comes from ignition switch, the ignition power transistor/ignition module controls the ground for the coil. My info says you crank and cam position sensors are built into the distributor. Sorry, I know very little about a Mitsubishi, I can't help you diagnose.

You may need to use a jumper wire between the threaded part of the plug and the cooling fins. You do not have to bend up the electrode.

Ignition module gap
Place a business or index card between the fly wheel and coil, rotate until the magnetic attraction pulls everything tight together. Tighten the coil screws, rotate the flywheel until the attraction eases and remove the card. Ensure nothing contacts when flywheel is rotated.

Have no spark. Changed coil & CDI box so far. still no spark. Is it the internal coil? 1989 enticer 400T/R


Hi and welcome to FixYa,
Initially, suggested checks on the wires:
  • black of igniter unit tied to ground;
  • orange wire from igniter to ignition coil with pulsating voltage when starting;
  • gray wire from igniter to ignition coil with pulsating voltage when starting;
  • IGN + 12 on red/white wire to igniter and ignition coils from engine stop switch;
  • IGN + 12 on red/white wire to engine stop switch coming from 10Amp ignition fuse;
  • pulsating low voltage from pickup coil between the wires black/white, white/green & yellow/red.
Postback results of above voltage tests.
Good luck and thank you for asking FixYa. Happy Holidays.

Honda civic(98) no start


there are two blue wires at the module one is out put to the tach the other is coming in from the coil if this wire does not have 12v coming in with the key on check for 12v on both sides of the coil with the key on you should have 12v on both side if you dont swap outt the coil ( but normally in this case when you dont have spark your crank sensor is bad )

1993 ford mustang doesn't start


have you checked the ignition control module?? Are you pulling up any codes. The ignition control module is the little gray box that is attached to the intake manifold. If it is bad and is not sending the power to the coils it will not fire. If it is cranking over then it may be the module. If you have a check engine light that comes on. Then you need to pull the codes up to see if it is a faulty sensor or if your IDM(Ignition Diagnostics Monitoring) is good. If you get the shop manual from the local parts store you can pinpoint it with a digital multimeter to see if it is getting power to the module. If it is good then the module is shot. Most of the time it is the module.

You can get it at the local parts house too or order it..


i hope that this helps you out. If you have any questions feel free to ask. I have a 1993 Ford Mustang LX with the same engine.

One other note if it was the coils which is the little black boxes with the wires coming from them. If one was bad you could still get the car to start. It just would'nt start everytime..
