Look for a relay on engine compartment on fuse panel, Relays are square plastic boxes plugged to fuse panel 1" Tall By 3/4 usually their size look on fuse cover for details or order the book on linehttp://www.themotorbookstore.com/carmanuals.html

What can I check next after replacing starter the car still wont turn over. not a sound.


The starter wire runs from the ignition switch to the neutral safety switch (located on the transmission), then to the fuse and relay, then to the starter solenoid. Pull the crank/starter fuse look at it, put it back in if it is good. This gets rid of corrosion problems. Try to start. If it doesn't I would go to the safety switch next.

Tip

Trouble-shooting your Isuzu starter..


Basic operation of a starter:
Your engine's starter motor is an electrical motor that is used to rotate the engine in order to get it to fire up. This motor draws a large amont of current from the battery (in the order of 70 Amps and up). In order to supply power to the starter a solenoid is used, it acts as a switch between the battery and the starter motor. This solenoid also engages the starter gear with the engine's flywheel and disengages it once the engine is started. Because the circuit for the solenoid also draws a heavy current a further relay is needed to control it.
The diagram below shows the electrical layout of the starting system.
  • i : Battery
  • ii : Starter relay(located in the relay box in the engine compartment)
  • iii : Starter solenoid
  • iv : Starter incorporating solenoid and motor.
  • v : Engine
  • vi : Battery earth cable
  • vii : Engine earth cable
  • viii : Ignition fuse
  • ix : Starter fuse
  • x : Solenoid to starter supply cable
  • xi : Ignition switch
  • xii : Starter motor
When the ignition(xi) is turned it supplies power from the battery through fuse (viii) to the starter relay(ii).
The starter relay activates and supplies power to the starter solenoid(iii) via fuse (ix)
The starter solenoid activates and connects power from the battery to the starter via a short cable(x) between the solenoid and starter motor. This allows the starter motor to turn.

General trouble shooting.
Turn the ignition off.
1/ First you need to check that the fuses are intact.
Keep the ignition off. Place the vehicle in Neutral. Chock the wheels and engage the parking brake.
2/ To prove the starter motor, connect power from the battery positive to the cable (x). This must be done with jumper cables. Touch the jumper cable to the connector on the back of the solenoid where cable (x) connects. Take care not to short circuit the jumper cable to the engine or vehicle body. It can be a tight fit and might not always be possible. If you hear the starter motor spin then it is working along with the engine earth cable. If not, connect the negative lead of the jumper cable between the battery and the starter motor body or any other bare piece of metal on the engine and put the positive lead on cable (x) again. If the starter motor does not spin it needs to come out for repair/replacement. If it spins check both the battery earth cable and engine earth cable and repair where nescasary.
3/ Once the starter motor has been proved move on to the solenoid. Remove the thin wire from the solenoid. Using a small piece of wire, connect battery positive to the connector where you just took off the wire. The solenoid should kick in and the starter motor will turn the engine. If the solenoid does not kick in, remove the starter for repair/replacement of the solenoid. If the solenoid kicks in then replace the starter relay.

If the starting circuit still does not operate the fault will be in the wiring. This needs reasonable expertise and if you dont have a voltmeter handy is not advised.
Bear in mind on automatic transmission vehicles there is an additional switch (Mode switch) wired in between the ignition switch and the starter relay. This switch is on the transmission itself and if faulty will not allow the starter to operate even if steps 1 to 3 were successfull. The same goes for the anti theft/immobiliser system.

The following is specifically for Isuzu Trooper and Rodeo :
  • i : Battery
  • ii : Starter relay(located in the relay fuse box in the engine compartment designated X-17)
  • iii : Starter solenoid
  • iv : Starter incorporating solenoid and motor.
  • v : Engine
  • vi : Battery earth cable
  • vii : Engine earth cable
  • viii : 10A Starter fuse C-1(Fuse box: LH footwell on LHD vehicle, RH dash on RHD vehicle)
  • x : Solenoid to starter supply cable
  • xi : Ignition switch
  • xii : Starter motor
  • xiii : 80A Main fusible link FL-1(Relay fuse box)
  • xiv : 50 A Key SW fusible link FL-2(relay fuse box)
  • xv : Mode switch(A/T only - mounted on the side of the transmission) and for 6 cylinder manual transmission engines this is the clutch start switch mounted on the clutch pedal.
  • xvi : Anti theft system
  • B2 : B2 on ignition sitch
  • ST : ST on ignition switch

How to wire a relay

I have a 2004 Chevy trailblazer no start no crank but if I put key on hot wire the starter it will start I replace new ignition switch and new starter relay b


Before you do any thing check for loose or bad connections. Also check you ground connection to engine. Check Fuses, relay and for a Fusible Link open circuit. Now let me explain what a Fusible Link does. They are short lengths of small gauge wire installed between the Battery and the Ignition Switch, or the Battery and the Fuse Panel. They'll melt and open the circuit before damage occurs in the rest of the circuit. I hope this was helpful you.

Have a ford f 350 2004 model manual ****** motor wont turn over replaced clutch safety switch ck starter relays can b pull started


Did you check for power at the starter ignition terminal? It is the small YELLOW/BLACK wire on the starter. If there is power there, replace the starter. If there is no power there, you should check your starter relay an its associated fuses.
The relay primary side is protected by fuse number F2.31 (15 Amp) in the Central Junction Box. This fuse provides power to the clutch safety switch on the WHITE/PINK wire. Then the power leaves the clutch safety switch on the TAN/RED wire and goes to pin 86 on the relay.

The relay secondary side is protected by fuse number F2.113 (30 Amp) in the Central Junction Box. It provides power at pin 30 on the relay, which is also located in the Central Junction Box.

Pin 87 at the relay is the YELLOW/BLACK wire metioned earlier and goes to the starter motor.
Pin 85 at the relay is the primary GROUND. This should be ground at all times.

The ENTIRE starting system can be checked/diagnosed from the pins at the starter relay if you use the correct methods and equipment.

Keeps blowing the starter fues


Hi, if you're talking about the 10 amp fuse #12, pull out the starter relay and put in a fresh fuse. Try to start the truck and then check the fuse. If the fuse is OK, get a new starter relay. If the fuse burned without the relay, there is a short between the ignition switch and the starter relay. If you have a manual transmission, you can further isolate the short by pulling the connector off the switch above the clutch pedal. Put another fuse in and try again. If the fuse burns, the short is between the ignition switch and the clutch switch. If not, it's between the clutch switch and the starter relay. Please let me know if you have questions, and thanks for using FixYa.

Car won't start, no sound when I turn the key. New starter, battery, and alternator. What could the problem be? Drove it for about 2 hours then parked it for about 3 hrs. Tried to start it acted like it...


Hi, there are a few things it could be. Safety interlock, starter relay, ignition switch, or starter solenoid. If you cannot hear the start relay click, the problem is probably with the interlock connection on the transmission range sensor. First check the 10 amp starter relay fuse (#7 in the cabin) . If the fuse is good, you can bypass the interlock by pulling the connector off the transmission range switch and connecting the terminals of the tan and brown wires using a paper clip. If this allows the car to start, replace the range switch. If not, the problem may be with the ignition switch. To check the ignition switch, use a 12 volt test light or voltmeter to check voltage on the brown wire of the connector at the transmission range switch when the key is turned to start. If that brown wire is not hot with the key turned fully, the switch or the fuse is bad. If there is power all the way thru to the relay but the relay does not click, swap out the relay. You can borrow another relay to check this out. The A/C clutch relay is a good one to borrow--it's right next to the starter relay in the relay box by the battery.

If you can hear the start relay click when you turn the key, the problem is probably the starter solenoid.
If you need instructions for replacing parts or if you have any questions, please let me know.

Won`t star


Hello Sir:

There are 2 Problems that can prevent your car from starting:

#1) Make Sure your getting Fuel

#2) And Check to see if you are getting Spark to your Spark Plugs,By pulling off 1-Spark Plug wire and take plug out also, Put spark plug back in the Wire. Have someone crank the engine over,and see if theres Spark at the Spark Plug.

#3) If your car is'nt even cranking over,then the problem is in either your Ignition switch,starter relay,starter,or it can be as simple as a relay or Fuse, check in your fuse box inside,to make sure ALL fuses are good.

#4) Then under your hood you should see a plastic Cover Fuse and Relay Block as well, Check these also,Mainly if its labeled Crank,or starter. Also check your Starter relay. they are a Larger componet in the box under your hood.

#5) to check this relay you'll need a OHM meter to check for resistance. also check the EMC Fuses or Relays.

#6) if no fuel check fuel pump fuse and replace fuel filter 1st.

#7) If no Spark make check your Coils.I'm sure if you follow these tests you'll locate your problem.

PLEASE let me know how my Solution helped you by Voting for the Quality of my Solution./

My 98 jeep grand cherokee wont start. It doesnt even click or turn over. battery is fine, headlights, dome lights, all go on. Radio doesnt work with ignition on. I checked ALL the fuses, I replaced the...


fuse 8 40a supplies power to starter relay and ignition switch, to close the starter solenoid and engage the starter which draws directly from the battery. check to see that the starter relay is closing, if not ensure that the park neutral switch is not faulty (open circuit), it provides path to close relay (ground side) on the 85 - 86 terminals. if the starter relay does not close the starter will not run. if you have a spare relay swap out the relay for a quick fix attempt. hope this helps

DOES THE CAR SOUND LIKE IT WANTS TO TURN OVER AT ALL?

Why are you having to jump it? Bad battery...too weak....weak battery not supplying enough juice to the starter to turn the motor over....
