Well it may run and all but it could be mis-firing and would degrade performance. I would make sure to put all the wires on in the correct order.If it runs fine, then it might all be on right after all but if any are in the wrong place, you would notice but not to much considering it is a four cylinder, sometimes you never notice a mis-firing cylinder. Point being is the wires do need to be in the right order for the car to run smooth and correct. Hope this helps.

I an looking for a diagram how to change plugs on a 3.0 v6 24v alfa romeo 1999 model please


no need for a diagram
take a photo before you start doing the work

you may have to take of plastic covering to see all the plug leads

if the plugs are deep in the motor in plug tubes
you use the plug lead long part to clip onto the undone plug and pull it out

best do one plug at a time
pull of the plug lead / undo spark plug / fit new spark plug
replace lead
repeat till all plugs are changed

I had the sparks plugs change and the ignition coil change but still skipping


Could be Distributor Points,
Quick clean with fine file or wet&dry to see if it makes a difference.
Could be Capacitor (Condenser) across points. Distributor Cap, could be cracked or have a HV carbonised track.
Distributor Rotor Button or individual HV leads to spark plugs. Check HV leads with Ohms scale on Multimeter. Or swap lead with one of the others. Or substitute HV Lead one at a time to determine if missing spark.
Process of elimination from easiest to hardest unless you have the knowledge & tools.
Good Luck

I drive a 95 toyota 4 runner.I would like to know the right way to check my sparkplug wires if working p roper.


You can fabricate a tester from a 6 inch long mongol pencil. Sharpen one end and drill a 1/8" hole in the middle. Now remove the sparkplug wire from each sparkplug and insert the pencil onto the sparkplug wire with the dsharpened end connected or touching the ground or any metal part of the engine. Start your engine and you should see sparks jumping on the drilled hole on the pencil which indicates that your spark plug wire is okay.

Initial start up the engine sounds like its running on 2 cylinders under powered intil the temp gauge reads normal ???? any body got the answer please


Cold starting misfires can often be caused by either tired high tension spark plug leads or ignition coil packs. If replacing leads, then replace with a full, new set. Coils can be changed individually, but it is often the case that if one has failed, then the others aren't far behind. Some cars have individual coil packs on each spark plug. Some cars have a single pack for all plugs and some have coil packs which may control two or more plugs.

To check for a misfire (ignition failure) follow these steps:

(Cold start) (Use a pair of insulated pliers)

1) Start the vehicle

2) When the vehicle starts misfiring, disconnect plug leads or coil pack connections one at a time. If the vehicle idles even more roughly, then that plug or pack should be considered fine.
Replug each connection before disconnecting the next one. Once you disconnect a plug lead or coil pack connection and find no difference in poor engine running, then you have likely found the offending cylinder. Check the spark plug condition, lead and/or coil condition and connections on that cylinder.

3) Replace components as necessary.

I have 1986 Alfa Spider that won't start. Car has been sitting for a year. I replaced battery, fuel tank, fuel sender unit, both fuel pumps. I seems that the in tank pumps is not getting any po


Could be the main or fuel run relay located in the compartment under the luggage rack, passenger side, main relay also, fuse for the fuel relay 8amp. Electronic Control Unit is also located there.

Could be electrical, Hook up a timing light, three leads: Power, Ground, and one that goes around the wire to #1 cyl. Turn the engine over and see if there's firing. Note: u can check all 4 spark plugs this way.

Fuse lead goes to pin 30 of the fuel relay, u can jump 30 across to 57 and check for the pumps running, if not, change-I suggest both relays, main and fuel run relays. Both pumps get their 12v DC from the fuel run relay, both should be running when you switch ignition switch to on, then a tachymetric signal is fed from the coil to the relay to keep it running.

Brought 1979 out of storage after five years. Put in new battery and all accesories work, car turns over but will not start. No spark was comming from plug wire so I checked the coil. No spark came from...


Most likely the points, but check the low tension coil wiring as well. If the points have got stuck together during storage or if the wire to them is disconnected then you won't get a spark. If they've slipped totally closed you won't get a spark either. Replace the condenser at the same time, they don't last forever and are cheap.

After changing the points or re-gapping them, you MUST re-time the ignition, statically to begin and then dynamically once the engine is running. ****** the timing slightly from standard to take account of lead-free fuel, unless the car was supplied from new to a lead-free country.

Mazda Eunos 500 - Engine lacks power - investigation reveals strong sparks on all cyls fuel at all cyls compression to specification on all cyls timing ok. Removing spark plug lead on cylinder one makes no...


You said compression is good then i would say you may have a bad coil , unless one coil runs all cylinders, but could still be a coil,,next thing i would check would be the injector make sure it gets a pulse if it does then try switching injectors from that cylinder to another cylinder and see if the weak cylinder changes with the injector change, if it does then you have a bad injector,

Where is distributor located1995 960 6cyl


hi, if you follow the leads that come from the top of the spark plugs where all these leads plug into is the distributer their will be four leads running along the outside going to each spark plug then the lead that goes into the center of the distributer goes to the coil.

So if you follow the four ht leads from the spark plugs what these all plug into is the distributer, if you are removing the distributer then make sure you mark where each lead goes as you need to put them all back in the right place.
Its best if you mark say the first lead with a 1 and then write a one onto the distributer where that lead goes into use permanent marker pen to do this so it dont rub off. getting the leads the wrong way round will mean the car will either miss fire or not run at all so just keep it all marked up properly.

Let me know how you get on or if you need further assistance ok
