Pull the small wire off the relay and have someone else turn the key to start position and check for voltage on that small wire, if there is no voltage present your problem may be the ignition switch mounted on the colum under the dash.

Replacing a fuse engine wont start 2005 hummer h2


Is the anti-theft light lit on the instrument cluster ? Won't start how ? When you turn the key to start , what happens ? Nothing ? This would be a No crank - no start condition . Now if you turn the key to start and the starter engages and spins the engine and it doesn't start an run , this is a engine cranks no start condition ! Now which is your problem ?

There are two fuse's IGN A fuse 40amp and IGN E fuse 10amp ,both are located in the under hood fuse/relay box . Also there is starter relay located in the same under hood fuse /relay box . There also is a crank fuse 10amp in the under hood fuse box . Besides the fuse's and relay ,the ignition switch or the PNP - park neutral position switch could be bad . Testing the whole starter circuit should be done ! How to voltage drop test starter motor circuit

I have a 2002 mercury mountaineer that wont turn over at all the battery is good and there's a clicking noise coming from the relay box what would that be


The clicking noise will be relays. Possibly a starter relay and thats normal. Sounds as if the starter moter may be the culprit. You have to check for start power at the starter solenoid while cranking before any further daignostics can be done. Sometimes tapping on the starter motor while holding the key in the crank position will start the vehicle. If so the stater motor is defective

My 1999 cougar clicks but wont start up when i turn key


first make sure battery is charged if so then then check the relay in the fuse box under the hood find the relay that marked "ing" pull that relay then find a nother one to inter change with it, if car still wont start then ou will need to see if the in line fuse on the starter wire is good or blown if its good then you will need to pull the starter and replace it. hope this helps you

Engine wont turn


1. Make sure your battery is fully charged.
2. Check connections from battery to starter relay.
3. Make sure you have voltage going to the start side (small wire) of the relay with the key in the "start" position.
4. If you don't have voltage going to the start side of the relay (small wire) with key in the start positon, then your starter switch is faulty (under dash usually mounted on top of steering column).
5. If you have voltage to the start side of the relay (small wire) with key in start position, and it don't click when trying to start your car, then the starter relay is bad.
6. If your starter relay clicks, but engine don't turn over, then the starter is faulty.

2001 blazer wont crank, headlights come on when key is off,can get truck to run after taking cover of starter relay,and fuelpump relay turn key on, and manually push relays to start.


At the moment, I'm only talking about starter relay. The starter relay has two sides, the load side and control side. The load side is that line with arrow, terminal 30 and 87, terminal 30 is hot all the time, plus, see that fuse on the load side. If you unplug the starter relay, key in the on position, on position is where dash lites come on, Then use jumper wire between terminals 30 and 87, at the least it should crank the starter motor and it might start. If you try that, make sure tranny is in park or neutral and parking brake is set.
If you get a reaction, the problem should be on control side of starter relay, right side in the picture. Terminal 85 and 86, the control side needs voltage and ground. You can see crank fuse, goes hot with key in the crank position, not only check fuse check for voltage on fuse circuit. As you can see, on the control side the neutral or clutch switch, depending on the tranny, is involved The ground for the control side is a chassis ground. As far as the fuel pump, other than the initial prime, fuel pump will not run w/o rpm signal, you have to crank it to get rpm signal.

Every time I turn the key to start the motor it blows the 30 amp fuse what is the cause and how do I fix it


if the fuse is blowing when you turn key to start position then this is where to look for the fault ,between the ignition switch and the relay then the other side of the relay to the starter motor solonoid

2005 Sedona wont start, wont take a jump. Radio works and lights come on but wont turn over. Friend said to follow the positive battery cable to its end and id find the starter. cant find it. looked here...


OK, even if you find the starter, you'll have to find a way of testing it.

Starter Testing Starting System Voltage Drop Tests NOTE: The battery must be in good condition and fully charged prior to performing this test.
There are three area of the starter motor circuits that voltage drop test can be performed on. These include:
  • The starter feed circuit
  • The starter ground circuit
  • The starter solenoid.
Starter Feed Circuit
  1. Disable the fuel system by removing the fuel pump fuse or the fuel pump relay.
  2. Verify that the vehicle will not start.
  3. Connect the positive lead of a voltmeter to the positive terminal of the battery.
  4. Connect the negative lead of a voltmeter to the starter B+ terminal.
  5. Turn the ignition key to the START position and note the voltage displayed on the voltmeter.
    • Ideally, there should be no more than 0.1 volt drop for each connection displayed on the voltmeter. No voltage should be consumed by the vehicle wiring
      1. If the battery cable connects directly to the starter motor there should be no more than a 0.2 volt drop measured
      2. If the vehicle uses a starter solenoid between the battery and the starter motor terminal there should be no more than 0.4 volt displayed on the voltmeter
Starter Ground Circuit
  1. Disable the fuel system by removing the fuel pump fuse or the fuel pump relay.
  2. Verify that the vehicle will not start.
  3. Connect the positive lead of the voltmeter to the case of the starter motor.
  4. Connect the negative lead of the voltmeter to the negative terminal of the battery.
  5. Turn the ignition key to the START position and note the voltage displayed on the voltmeter.
    • Ideally, there should be no more than 0.1 volt drop for each connection displayed on the voltmeter. No voltage should be consumed by the vehicle wiring
      1. If the battery cable connects directly to the starter motor there should be no more than a 0.2 volt drop measured
    • Starter Solenoid
  6. Disable the fuel system by removing the fuel pump fuse or the fuel pump relay.
  7. Verify that the vehicle will not start.
  8. Connect the positive lead of the voltmeter to the case starter B+ terminal.
  9. Connect the negative lead of the voltmeter to the lug (the starter M terminal) that connects the starter solenoid to the starter motor.
  10. Turn the ignition key to the START position and note the voltage displayed on the voltmeter.
    • Ideally, there should be no more than 0.2 volt drop across the starter solenoid displayed on the voltmeter.
In general, there should be no more than a 1.0 volt drop throughout the entire starter motor feed and ground circuit. Any voltage drops measured in either the feed or ground circuits after connections have been cleaned will require replacement of the affected battery cable. Typically, any voltage drops measured in the solenoid are repaired by replacing the starter motor.

Hi,
Sounds like a bad starter relay. When you turn your key to start, current flows through a relay which in turns supplies 12 volts to the solenoid on your starter motor. As you alluded to , typically the common clicking sound that we all hear occasionally, is usually related to a flat battery or bad starter motor, but as you have had these checked (by a professional?) the only possibility is the relay that supplies 12 volts DC to your starter motor solenoid.
Thought you might find this interesting to help you understand ignition systems:

No power to the solenoid on the starter


There is no relay for the starter motor.Disconnect the plug from a tumbler and just short the positive wire with starter motor one.If O.K. the problem is into ign.switch.If your VW have automatic gearbox-check parking switch on gear lever.
