Are you checking to see if the starter is bad? If so, testing this way is a power and continuity test, and testing a starter in this way will not neccessarily tell you whether it is godd or bad. If the brushes or the armature is worn out, the power and continuity will test good, but the starter still will not work or work part time. The best way to test a starter is to remove it and have it tested at any auto parts store.

Do you know what the relay switch is ?
The starter motor solenoid relay switch:
  • controls current to the starter solenoid.
  • is engaged by the ignition switch.
  • connects the battery (10655) to the starter motor.
The TR sensor on automatic transmission-equipped vehicles prevents starter motor engagement unless the transmission is in the NEUTRAL or PARK position. For additional information, refer to Section 307-01A or Section 307-01B .

Why will my gas gage stay at full on my 2001 excursion


The gauge is faulty or the sending unit in the fuel tank is bad ! There is away to test it, find a wiring diagram an locate the two wires at the fuel pump sending unit connector . Go to radio shack or some other electronics store an buy some resistors of differing resistance , I'm not sure of resistor sizes , I will look it up on my ford service info system. If you jump the right resisters into the fuel sending unit circuit you can make the gauge show 1/4 - 1/2 - 3/4 an full. If it move to those positions with the right size resistors it's not the gauge but the sending unit in the gas tank ! Diagnosis of Stuck Fuel Gauge Is it Gauge or Sending Unit

2000 Ford Ranger wont start or turn over.


What is litre size of engine, automatic tranny or manual? Check the wiring circuits at the starter for voltage,use a test light, One circuit is hot all the time, the other circuit goes hot when starter relay is energized. Any testing at the starter make sure tranny is in park or neutral and the parking brake is set. The clicking noise may be the starter relay.

Pontiac vibe ignition switch? Intermittent dash


Basic electrical problem . loose connection on a ground circuit ,high resistance . There are no magical fixes for automotive electrical gremlins . Finding electrical wiring diagrams an voltage drop testing the electrical circuits is the only way to find the problem .
When the ignition switch is placed in the Start position 12 volts is supplied through the Park/Neutral Position Switch or Clutch Pedal Position switch to the switch and coil side of the Starter Cut Relay. If theft is not active the Theft Deterrent Module grounds the control side of the Starter Cut Relay closing its switch. Power then travels to the coils side of the ST Relay with ground at G200 closing the ST Relay. Power then flows from the Main fuse in the Fuse Block - Underhood through the switch side of the ST Relay and then to the S terminal of the Starter Solenoid. Ground is found through the engine block.

Ford econoline wont start


https://s4.postimg.org/898usmifh/starter.jpg

Click on the link. I tried to get all on the same page, hope you can read it? It's for the starter motor circuit. You need to test when problem is ongoing.
Make sure battery has a full charge and connections all good. I don't know liter size of engine, whether it is diesel or gasoline? The diagram is for 5.8L gas engine.
Any testing at starter motor make sure tranny is in park or neutral and the parking brake is set. Two voltage circuits at starter motor, one comes from the battery, hot all the time. The other circuit goes hot when starter relay is energized. Check the fuses for voltage in the diagram. The starter motor usually grounds through engine block.
Unless you can do some testing, I don't know how to help?

Power doesn't go from the steering column to the starter ! When you turn the key to start it sends a voltage input to the PCM - engine computer . Then if fuse F2.4 5amp is good B+ voltage goes through the DTR - digital transmission range sensor , If the vehicle is in park or neutral to the starter relay . The PCM will turn on a ground to that circuit energizing the starter relay ! This will happen if there are no issues with the PATS system ! passive anti-theft syatem . Do know what a wiring diagram is ? Always look at a wiring diagram to find what all is involved in a circuit . Here is a web site for free wiring diagram's http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine size . Under system click on engine ,then starting in subsystem ! Click the search button ,then the blue link ! If you don't know about computer controlled systems suggest you take your vehicle to a qualified repair shop .
Watch videos on youtube for basic automotive electrical testing ! Never assume anything , learn how to test if you want to fix vehicles !

Rather then just replacing parts testing the fuel pump electrical circuit is the proper way to diagnose . Do you know how to use a DVOM - digital volt ohm meter , how to use a wiring diagram to pin point testing points in a electrical circuit ? How to use voltage drop testing in a circuit to find which part of the circuit has the problem B+ or ground side . Yes it can be very agrivating if you don't know what your doing .
