Check the ignition module next to the coil , this is normally the culprit

I am working on a 1993toyota Corolla 1.8 no fire changed whole distributed assembly tested power coming to coil it's good still no spark checked all fuses there ok any sugestions


if the coil is tested fully and is good where have you checked for it being good? have you checked if the HT lead from the coil to the distributor is carrying power? If you have power at the distributor cap , all the contacts are good, the rotor is fine, (check current at the distributor cap centre pin) then the likely problem is the machanism for firing, i.e. Hall sensor . I would check all the HT leads, distributor cap, rotor etc. you should carry out the checks systematically. I.E. First check at the coil with a multi meter. Then check at the end of the Ht lead from coil to distributor , actually within the lead itself , for current. then attach it to distributor if it shows a current...if you are getting a current from the distributors centre pin the issue is probably the cap itself, the rotor arm, the firing system, it will probably be electronic as mechanical distributors went out some years before I think. or if that is okay, the leads themselves. I would guess that is is distributor cap or firing system related'

Engine runs at idle all plugs fire, but when the engine is throttled is starts to miss and runs rough if i put a strob light on the ht wires you can see the miss fire on all the leads


If you can see electrical sparks across the ht leads then you may have a tracking/shorting problem somewhere.

You haven't said what vehicle you have, but a rotor arm or distributor cap can crack and cause the problem you describe. As can a coil/ignition pack and of course, the leads themselves.

There's no real way of testing ht leads apart from replacing them. The same applies to a rotor cap and rotor arm.

Check inside your rotor cap - if you - can - look for 'tracking' marks... burning. Try cleaning it and spray everything with an ignition sealant to see if that eases the problem.

However, replacement - if you suspect any of these items to be at fault - is the only real answer

1990 geo storm sohc is running rough. Parts that are new: cap, rotor, plugs wires,plugs, pickup coil, and the ignition module looks brand new. The coil is old, but is still sending spark through all t


the timing is 180 degrees out so ignore where no 1 lead should be and rewire the HT leads to the new position for no1 cylinder. The crank timing mark should be on 10 degrees advanced. Engines are timed off the crank position so forget the cam position.
Or you can start again. Remove no 1 plug and turn the engine over until you feel compression under your finger over the plug hole. Set the timing on the crank to 10 degrees before tdc. Position the distributor so that the point of the star is directly opposite the exciter coil in the distributor. The rotor button should now be facing no 1 cylinder plug lead adjust the HT leads so that they will fire in the 1342 firing order. Start the engine and with a timing light attached to no 1 plug lead adjust the timing mark to specifications by turning the body of the distributor.

Car wont start but kicks over


Since you do have A fully charged battery and also you do receive fuel smell after crank start and the car wont start,either you do have an Ignition fault means not giving the spark,advice remove the spark plugs and check whether are wet with fuel,see whether are black,if so change them and before start check by leaving an HT lead off a spark and use one of the old ones connected to the HT lead and earthed to the engine,ask somebody to start the engine checking for any spark comes out. If yes then put the HT lead back to the new spark on the engine and try. If ther is not any spark,then you have to go backwards from the HT leads to distributor,Rotor Arm,Electronic igniter,Coil if is fitted,Fuse and relay. Good Luck.

No spark


First does the rotor turn when cranking engine?? possible timing chain is out or stripped gear..are you sure it has no spark??did you verify this with a high output spark tester ? did you spray starting fluid in the tbi unit ?

I have a Mazda astina 323 94 model it cranks but won't start doesn't seem to be any spark from the leads I have recently changed the leads , Im guessing it's the coil and distributor cap please help


1 remove the cable from the coil to the distributor.
check this agains earth, when you turn the engine over.

if spark, suspect rotor arm is not setting spark to each spark plug lead.
open distributor and clean the rotor arm with a cloth or wire wool
not sand paper as this will take off too much and cause a problem

2 check inside distributor for moisture. spray inside with WD40 or equiventy water repelent.

3 if not spark at coil open distriutor cap and with ignition on, open and close points in distributor with a screw driver and check coil again against earth again if you get sparh, problem is points not opening and closing.

4 turn over engine with distributor cover removed to see if rotor arm is moving if not then cam drive to distributor is defective. this controls points and rotor arm.

if rotor arm turning and spark at points but no spark at coil suspect Low tension wiring or coil needs replacement.

i hope this was helpful

My 1990 sierra has a miss in it when i accelarate. I replaced plugs and wires but not the fuel filter or fuel pump.I also smell fuel outside between the bed and cab on the drivers side


Check out the distributor cap and rotor arm, - and make sure the plugs ar gapped properly - should be 1mm on 1.6 1.8, and 0.75mm on the 2 liter.
Check the oil level urgently, if it has been misfiring for some time you will have acuumulated all that unburnt petrol in the oil sump!!! (you can test this by getting a bit of oil from the dipstick and putting a drop on your fingers, rub together and sniff the oil, if it stinks of petrol change it -you need to change the oil filter too since it wil be full of petrol tainted oil also.
Once you are sure you have good oil and either it was ok after testing it from the distick "golden, clean oil" or you replaced the contaminated oil and filter you can move on to sorting out this misfire.
- You didn't mention if you checked or replaced the HT coil - Check for strong sparking from the main HT lead from the coil itslelf, Pull the lead from the centre of the distibutor cap - have someone crank the engine while there is a "spare" sparkplug in the main ht lead (ground the plug to the engine, holding the rubber insulation of the cable with pliers - Use a normal HT lead if the main coil lead wont reach a suitable grounding point with the sparkplug) - check for solid bright blue spark, it should be regular timed, and strong EVERY time - any missing or weak sparks indicate electrical problem either - the coil is failing - or the battery is weak - or the distributor is faulty. - a faulty distributor would be expensive to replace and more so to repair, a reconditioned distributor costs around £120.
for now I assume the coil checked out fine and gave a strong steady uniform set of sparks. ----------------------- With a fully functioning coil, you're left with the distributor cap and rotor arm - the distributor cap comes off with 2 screws at the left and right sides of the cap between the HT Connectors - unscrew them - (note the original orientation of the distributor cap before you pull it off to aid refitting) you can now pull away the cap from the rest of the distributor.
INSIDE the CAP there are four "poles" round the outside, and a spring mounted contact in the center - make sure the poles are clean and shiny with only light markings at most, if they are blackened, whitened ro rounded and pitted then replace the cap - ford dealers or local part shop, most shops will stock both the rotor arm and distributor cap for around £15-30 - phone around for the best deal.
Still on the distributor is the rotor arm, this pulls off - it has to be pulled dead straight off the distributor shaft - once you have the rotor arm off you can inspect the metal contact on the top for general dirtiness and decay, it "should" be shiny brass/copper in colour. if it looks pretty bad, pitted or blackened/burned- - get a new rotor arm from ford dealers or from local part shop (not expensive)
Once you are sure of a clean or new rotor arm and distributor cap you can try the engine again - hopefully the misfire is gone.
If it is still there....
we are here

DISTRIBUTOR CAP - FINE ROTOR ARM - FINE OIL + FILTER NOT OVER LEVEL + CLEAN, NO PETROL IN IT HT COIL - GOOD STRONG REGULAR SPARK. -----

If it still misfires with all these things in perfect order then you are left with: Clogged Fuel Line/Filter or Failing Fuel Pump or Ignition TIMING - ( 10-12 degrees BTDC) have igition timing checked and set if not correct. OR... Faulty Distributor - pretty much worst case scenario. Tell me how you get on - Often it is the distributor cap and rotor arm - If not I hope its the fuel filter!
Good luck,
