    k thanxs. looks like its the coil pack.. i kinda thaught it was. but because only one of them (#4) wasnt firing i awsnt sure if the whole pack would be bad if only one wasnt firing. Also because of the price of the pack wanted to make sure that was the prblem before guesing at it... thanxs

Check compression, spray water on intake gasket to see if it gets sucked in. If these check out ok then then injector failed or is clogged. You will have to replace or rotate it to confirm. also rotate the spark plug to see if thats your problem

    also rotate the coil to see if it follows the coil

    when you only give 1 thumb for an expert that deals with this on a daily basis then you end up with no further help.. Good luck.

    only other option then is to go buy an injector or ..coil or intake gasket set, or valve job, or spark plug or wire. if none of this works then you need to replace the computer. if that doesnt work you then need to get a professioanal to look at it. Like I said rotate parts to see if the problem follows the part. if it doesnt then you have a valve or intake gasket or injector or computer issue since these parts arnt so east to rotate.

    on a 4 pak coil with just one misfire happening it usually is not the coil. if you had a coil on each plug it could be a coil. I would be more prone to suspect a bad injector or intake gasket leak or even ignition module, You did not state if you replaced the spark plugs yet so thats another possibility

I need ignition coil diagram ford focus 2000 LX (connections back 4321)


you have a single 3 or 4 pin connector to the coil pack. Someimes the wires get corroded and break off at the connector. Ford has a pigtail kit to fix that issue. Usually a misfire with the check engine light on.

Green/bluestripe is from ignition switch

Black/green stripe is to PCM (computer)

Black/orange stripe is to PCM

These last 2 wires are what the PCM uses to fire the spark plugs 2 at a time.

No spark on one cylinder on a 2000 ford focus 2.0


The coil fires two plugs at one time, so if the other plug is fireing also the problem maybe a wire or plug. Or possible bad coil if fire is weak on one side. Common problem.

Coil fires on #1 and #4 only. replaced coil several times


Try taking the wire and plug from #4 and plug it into #2 and #3 and see if you get a spark. This will eliminate the possibility of bad wires or plugs. If this proves fruitless, I am afraid that you might have a bad computer, because the signal to fire each individual plug comes from there.
