SOURCE: Car will not start.

first, you need to check the battery voltage.
it should be at least 12.5 volts.

if the voltage is right, try moving the shift lever while turning the key, or try starting in nuetral.

with the key in the off position, try to turn pulleys by hand, the engine could be siezed.

please rate my solution, THANKS

actually you probably have a bad ignition box. I had a ford that done the same thing. there is a spring in the ign. box that when u turn the key over and then let go it is suppose roll the key back.but after time it will get weak or break,or the box itself will break causing malfunctions.

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

1999 dodge ram van 3500 starter engages while engine is running only in park or neutral. Had to pull starter relay to disengage starter, also starter relay somehow connected to blower motor high speed


Check ignition key switch wiring. Could be a short between blower motor wiring and starter wiring. Try switching on high speed blower when ignition is on only (not started). If the starter cranks, then there is surely a leakage/short in the wiring.

What is causing my starter to engage while the motor is running and won't quit until you unhook the battery?


Ouch! Sounds like the Bendix on the starter motor could have been damaged, or possibly the starter relay. I'd check the relay first. With ignition and engine off. pull the small terminal on the relay terminal Labeled "S" for start. It is next to the Battery terminal. (See enlarged pix on the link below.) Next, try to start the engine. It should not even try. Then, reconnect the starter wire to the relay. Have a friend start the engine and then pull the wire from the "S" terminal. If pulling the wire kills he engine, the you probably have a bad ignition switch. If the starter motor is still engaged with engine running, then I'd suspect a stuck relay or stuck Bendix. Since the relay is the cheaper component of the two (10 to 25 bucks), I'd change the relay. If the relay doesn't remedy the situation, It's time to replace the starter/Bandix.

Car won't engage starter


At the starter relay, you have two red or purple wires, one goes to the starter and the other comes from a 30amp fuseable link. Is that fuseable link circuit hot ?
From the key switch, power goes thru the alarm relay, then the clutch safety switch or automatic selector switch, then to the starter relay. The fourth wire on the starter relay is a ground.
You should be able to put power to the starter relay on the white or yellow wire coming from the safety switch to make the relay engage.
My guess is something wrong with the alarm system.
