Ford F350

My 94 f350 will not start with the key , all of the gauges and glow plugs will turn on when I turn it to the on position but will not crank or click , But with the key on I can jump the fender solenoid and it will start up fine .

While you have someone hold the ignition key in the “START” position check for battery positive at the “S” terminal on the starter solenoid using a multi-meter.

When battery positive is seen at the “S” terminal with ignition key in the “START” position it proves the ignition switch, neutral safety switch and wiring harness are good. At this point you have narrowed it down to a faulty Starter Solenoid.

Starter Solenoid Replacement

  1. Disconnect the positive battery cable from the battery terminal. With dual batteries, disconnect the connecting cable at both ends.
  2. Remove the nut securing the positive battery cable to the relay.
  3. Remove the positive cable and any other wiring under that cable.
  4. Tag and remove the push-on wires from the front of the relay.
  5. Remove the nut and disconnect the cable from the starter side of the relay.
  6. Remove the relay attaching bolts and remove the relay.
  7. Installation is the reverse of removal.

I have a problem with my Ford Mondeo 1.8 Turbo Diesel 1997.

The problem is that when i first start the car it revs normally at about 900 RPM, but when i hit the gas pedal the revs go up and when coming back down they drop to 500 instead of 900. They do come back to 900 after a second but they drop so low as if the car will shut down.

This lasts for a couple of minutes and then goes back to normal. One key thing to note is that while this is happening drive belt that drives alternator is squealing. When squealing stops then things go back to normal.

I am no mechanic but this looks like an alternator problem to me. So can you help me with this one?

The car is an old injector pump diesel and has no electronic controlled units etc.. It should be easy to pinpoint the problem.

2012 Ford F150

What year engine will work in this truck? It is a 5L engine.

The 2013 Ford F150 is considered the Twelfth Generation Truck. It was manufactured from 2009 – 2014.


In 2010 Ford shifted its electronics from a GEM (General electric module) based to the computerized and programmable BCM (Body Control Module) Allowing for fewer parts differences and programmable upgrade options from the dealer or factory. Also in 2010 Ford reintroduced the 5.0 in the F series with its new 5.0 Coyote dual over head cam TiVVT engine with 360hp.

As part of a major focus on fuel economy, the entire engine lineup for the F-150 was updated for the 2011 model year. Along with two new V8 engines, the F-150 gained a new 3.7 Liter base V6 engine, and a powerful twin-turbocharged 3.5 Liter V6, dubbed EcoBoost by Ford. An automatic transmission is the only option. Other modifications include the addition of a Nexteer Automotive Electric Power Steering (EPS) system on most models.

According to:

Car got rear ended. No body damage. But now upon acceleration or slowing down car will make a popping noise. Popping noise will happen only once per acceleration or slowing down.

Noises can be difficult to diagnose. Follow the above link to get a better idea of what it might take.

In this case I might see if I could replicate the popping noise by bouncing up and down on the vehicle to see if it is a suspension issue. Then maybe have someone rev and torque the engine(in gear) while you look at the engine to see if a motor mount is broken.

Added MERCON V instead of MERCON LV 2010 Ford Fusion

2010 Ford Fusion

What happens if I add wrong transmission fluid? After adding I noticed it was wrong one. It takes MERCON LV and i put half a quart of MERCON V.

Not sure what if anything would happen. In my opinion you will need to drain and refill the transmission as the two fluids are not compatible.

Transmission Fluid Drain and Refill

Item Specification

Motorcraft® MERCON® LV Automatic Transmission Fluid

XT-10-QLVC (US); CXT-10-LV12 (Canada)


NOTE: In order to completely clean the torque converter, this procedure needs to be carried out 3 times.

  1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Jacking and Lifting.
  1. NOTE

    NOTE: If an internal problem is suspected, drain the transmission fluid through a paper filter. A small amount of metal or friction particles may be found from normal wear. If an excessive amount of metal or friction material is present, the transaxle will need to be overhauled.

    Remove the transmission fluid drain plug and allow the transmission fluid to drain.


  1. Install the transmission fluid drain plug.
    • Tighten to 12 Nm (106 lb-in).

  1. Fill the transaxle with clean transmission fluid.

  1. Start the engine and let it run for 3 minutes. Move the range selector lever into each gear position. Repeat Steps 2, 3, 4 and 5 two more times.
  1. After the transmission fluid has been changed a total of 3 times, using the scan tool with the engine running, check and make sure that the transmission is at normal operating temperature 85-93°C (185-200°F). Check and adjust the transmission fluid level and check for any leaks. If transmission fluid is needed, add transmission fluid in increments of 0.24L (0.5 pt) until the correct level is achieved.

MERCON LV ” Low Viscosity” is not compatible with MERCON V. The LV is supposedly a “lifetime” fluid, so I’m guessing it’ll be a while before we find it on shelves at Pep Boys. And reading the text, it looks like “anti shudder” and “friction modifiers” are the Big Deal with this stuff.


Mercon V was developed in the 1990s and was one of Ford’s most commonly used transmission fluids until it was phased out in 2008 in favor of Mercon LV. However, Mercon LV and Mercon V are not compatible, so any Ford vehicle manufactured before 2008 requires Mercon V.

2011 Ford Ranger Thermostat Replacement

My Thermostat wasn’t working properly so I took it in to get replaced. The Guy at the desk said i had to buy the Housing along with a Thermostat as it comes in a Kit. I checked my truck before & there was no leaks or smell. This cost me an extra $150. I would like to know if I needed the Housing or just replace the Thermostat? Thanks, Dave.

The thermostat is a part of the housing in the 2.3L engine but not the 4.0L engine. So the entire housing would need to be replaced if you have the 4 cylinder engine but not if you have the V6. See the thermostat diagrams below for reference.

Fuel Pressure Regulator 1997 Ford Taurus

 Ford Taurus

I have a 1997 Ford Taurus GL. Recently, Car dies randomly….so far when just at low speeds & when turning steering wheel to left just a little bit. In panic, even with the car in drive, I turn the key and it starts again. What could that be?

I took it to the mechanic & no OBD codes were found.

Alternator is good & Battery is brand new with clean tight connections. All ground cables going from engine to battery have been cleaned.

Mass-air flow sensor contacts have been cleaned.

To check next,
fuel pressure (at idle it should be around 30-35PSI. On a light to moderate throttle, it will dip slightly to 25-30 PSI.)

Check Cam shaft resistance sensor.

check fuel pump

bad fuel filter?

bad distributor cap?

dirty air filter?

dirty catalytic converter?

Fuel pressure should increase on moderate throttle. Wouldn’t hurt to replace fuel filter and recheck fuel pressure readings. The Auto Repair Manual shows the fuel pressure should be 35 – 45 PSI. So I’m thinking the fuel pressure regulator is at fault.

Fuel Pressure Specifications – Chilton Manual

Description Specification
Engine Running

180-310 kPa

26-45 psi

Key On Engine Off

255-297 kPa

37-43 psi

Check the vacuum hose leading connected to the fuel pressure regulator first. Replace if cracked or brittle and test. If the hose is good, replace the fuel pressure regulator and test. Still not enough pressure, replace the fuel pump.

Fuel Pressure Regulator


  1. If removing fuel pressure regulator (9C968) with fuel injection supply manifold (9D280) installed in vehicle, perform Fuel Charging System Pre-Service Procedure and Fuel Pressure Relief procedure as described.
  2. Disconnect vacuum hose at fuel pressure regulator.
  3. Remove the power steering hose bracket.
  4. Remove fuel pressure regulator from fuel injection supply manifold and discard used sealing O-rings and face seal.


  1. Install fuel pressure regulator into fuel injection supply manifold using new sealing gaskets, O-rings and face seals. Tighten fuel pressure regulator to 25-34 Nm (19-25 lb-ft).
  2. Install the power steering hose bracket.
  3. Connect vacuum hose to fuel pressure regulator.
