You can try this, remove the plug wires and insert a phillips screw driver in each plug wtre, and hold shaft of phillips about 3/8 " from ground and have a friend crank over eng and watch spark . If no spark, check crank-posistion sensor. should be mounted at 10 or 2 oclock pos. above front crank pully. these have been known to go bad at times .

Hi,
 
Well problem with the lights is fixed. It turned out to be a severely corroded relay. And i replaced the spark plugs yesterday and its runnning way better. Just wondering tho, Does anyone elses spark plugs read that the engine is running hot? All four plugs were completely white. I put in new ones and made sure their gapped correctly. And so far no hesitation, or surging and the car feels looser.
 
Next question, Im replacing the fuel filter this week and just wondering if anyone knows which fuses i should pull as theres like 5 that are assigned to fuel.
 
Thanks for the help!

You do NOT nead to pull any fuses. Your fuel system will be pressurized so do this when the car is COLD. When you remove fuel line, do not have your face inline with filter and also wear eye protection. Make SURE your ign switch is NOT on.

Do NOT be concerned about your plugs burning white. Now if 3 were white and 1 was black,
then you get concerned.

I have a 2005 Ford Focus zx4 It has had some weird electrical problems. The trunk will unlock if the brake pedal is pushed. Also the left running lights front and back do not have any power. If you step on the brakes the front running light comes on. Now the drivers airbag light goes on and off intermittently. I

Well I replaced the ignition switch but it hasn't cured the problem. The wiring harness doesn't have any noticeable damage. I'm at a loss now. Is it possible there's a ground wire short somewhere? I'm close to just having it serviced.

#432 of 486 Running Ground Wires by thumper14

In several messages I have read where people have advised someone to run an extra ground wire to the car body. DON'T DO THAT. My son had a Ford Escort (this seems to be a common problem for Ford) and he had a headlight that kept going out. He bought several and finally checked the fused. It was no good so he put in a new one. That was the beginning. His lights would go off and on. The inside lights would go off and on when he was driving down the road. Sometimes things worked and sometimes they didn't. It died on him twice and had to be hauled to a repair shop. They had to disconnect the fuses for all lights or he had a "Christmas Tree" car with blinking lights and sometimes not working at all. It was draining his battery and ruined one. The car was great - if driven during the day but no lights. (Still had signals) They found that someone had run several ground wires, to "fix" problems before and it totally runined the car. It could have been fixed if they had done it right in the first place. By the time all this happened it would have had to been completely rewired and the mechanic said it would cost more than the car was worth. Good looking car - ran great but ruined because of someone running ground wires instead of having it serviced.

Well...it appears alternator number four this year will be in the works. My brother just called me to say after three weeks with the new NAPA Bosch alternator the company car is back to doing weird electrical things again including trying to stall and the check engine light has once again come on. Bringing it to a different mechanic Wednesday and see what they come up with. I asked NAPA to inspect the pigtail wiring harness for the alternator for corrosion and they said they did but I suspect they didn't. Will have this next shop look at it in my presence. Something is causing these Focuses to eat alternators and batteries so it has to be in the wiring and most likely a corrosion issue. Will keep those who are interested updated on this new round of repairs.

#434 of 486 2012 Ford Focus Instrument Panel by rnolen

Instrument panel will not come on when car is first started, then will work fine after 10-15 minutes of driving. occurs when temp is below 50 degrees. Has happened 7 out of the last 10 days. Has worked perfect the two times it was taken to the dealership. Both times it was left over nigth so it would be a cold start for the dealer.
Odometer, tachometer, none of the guages, LED screen and turn signal indicators will not work.
Car runs fine, exterior lights, turn siganal, Brake lights, radio and Iterior dome and floor lights work fine.
Any ideas how to resolve this issue?
