to test ht lead with out taking it out of coil pack. All you have to do is remove the 1 cylinder ht lead and pull the cylinder 5 ht lead out aswell and measure the resistance with multi meter. so now it will give you the reading. so its 1,5---2,6---3,4 ht leads.
4, you can always find this out for any car by having a look under the bonnet and counting the HT leads! *NB - HT leads are the leads from your coil pack which disappear into the engine, which provide power to the spark plugs.
take off ONLY the 'V6' engine cover (not the '5V' ones). Then you should see down the sides there are 3 HT leads going down each side. (if not, then i maybe forgetting some more covers or something needing to be removed). Take off each HT lead. Then, using a long spark plug wrench/remover, place the wrench down the tubes which hade the HT leads in, and move around until it clicks in, then screw counter-clockwise until the spark plugs are unscrewed. Then you can take the spark plug out.
They are attached to the end of the HT leads.
Engine won't start
i am confused i have a 1.25 ford fiesta and i have brought new spark plugs and h t leads and it is misfireing but the ht leads are in the correct order i think 1342 just wondered if any one could help me please !
to carry the electricity from the coil pack to the spark plugs
mg zr firing order
on the cab side of the motor. Just follow the ht leads!!
Check the grounds to the coil packs. If you have power and good ground there is a chance a new part is bad, or that whatever caused the last one to go bad happened again. Also check that the wire is good to the plug. There are a few ways to test that.
Try to use the length of the HT leads as a guide.
Firing order is 1-3-4-2.
