2007 Ford Fiesta Zetec Diesel

The engine cuts out while driving. It has done this several times at speeds ranging from 30mph to 50mph. The car usually starts straight away but recently has taken several attempts to restart. A fault finding diagnostic has recorded no faults. What could be the problem?

  • Clogged fuel filter
  • Contaminated Fuel

I recommend trying a different fuel station on your next fill up. Continue to drive until fault code appears.

I need assistance finding where a positive cable on the wiring harness connects to.

Starting system positive cables

One positive battery cable connects from the battery to the starter relay and the other to the starter motor. Of course if you have two batteries there is one that connects the two. See diagram below.

Alternator system positive cables

There are positive cables that come from the starter relay. They connect to the alternator and the fuse box. These cables contain fusible links. See diagram below.

2012 Ford F250

I have a severe shimmy / shake that starts once I hit 60 MPH and continues till around 70 MPH. I bought this truck used with 65,000 miles on it and what appeared to be new tires. The dealership changed the tracing bar and the dual stabilizer bar and re-balanced the tires and rotated the tires also trying to fix/find the issue. The issue only seemed different before these above fixes but now appears more different , severe and worse?

The issues at first were noticed at 35 or 40 MPH crossing a rough R/R Track that near about shook me off the side of the road and then settled down but really didn’t shimmy or shake to much at a high rate of speed , this was referenced as ‘ A DEATH WOBBLE ‘. Since the above fixes , the truck don’t shimmy or shake crossing the rough R/R track at 35 or 40 anymore but now shimmy’s and shakes severely once speeds of 60 to 70 MPH are reached. Any advise would be greatly appreciated!

Vibration at 60 MPH

Generally if a vibration comes on at a certain speed and then calms down at a higher rate of speed it is caused by a tire issue. Usually the tire issue is due to balancing. Sometimes what is called a flat spot will also cause this issue.

A good way to narrow this down is to first test drive and note any vibration. Is it more dominate in the front or steering wheel than it is in the rear or seat. Once noted, rotate both front tires to the back and test drive again. Note if the vibration has followed the tires. If it is now worse feeling in the steering wheel then you can start by re-balancing. Or in most cases replacing the front tires.

More than likely all the problems that were present caused extensive damage to the tires. Now that the repairs are made the only thing left to do would be to replace the tires.

Did I not seat the cross piece (Interlock) that goes through the shift tube sideways  into the shifting cradle correctly?

It is a 1997 Ford eE50 Econolin Club Wagon. I replaced my auto shift tube that was broke. The shifter is not moving since I put it back together. I believe I did not seat the cross piece (interlock) that is sideways through the new shift tube that seats into the shifting cradle correctly. Currently the shifter does not move.

It never hurts to recheck your work if you think you may have missed a step. However with the Ford Shift Interlock you may want to check for battery voltage at the shift interlock actuator. A weak or dead battery may be at fault. This could be from leaving the door open while working on it for a long period or simply age of the battery. Be sure to check the fuses as well. I have added the wiring diagram below for reference.

Shift Interlock System

The shift interlock system prevents movement of the transmission range selector lever from the PARK position with the ignition switch (11572) placed in the RUN position until the service brake pedal (2455) is actuated or until vehicle power is interrupted. The shift lock actuator is mounted at the base of the steering column and engages the transmission shift selector position insert to lock the transmission column shift selector tube (7212) and transmission range selector lever.
