    Not sure. I bough an ignition switch only 90.00. A educated guess. Alot cheaper then a started. The same shop will install it for half price. Aabout 35.00.

I have 96 isuzu trooper3.2l v6 stick shift all power is good but when i stick key in switch and turn it no sound at all what could that be

electrical power you meant is seems good.
engine power zero.
starter dead.
this is no crank, ill post again,. for this, done so many times.

i use this thing called a voltmeter and avoid this jiggery pokery below...... time is money.

1: fuses good.battery terms clean? (all fuses, if you lack the FSM to see which ones are IN PLAY.)
2: battery charged to 12.6vdc reseted?
3: jumper cable cranking work now>? off a running donor car?
yes, the battery was dead, or weak, or discharged, test battery, test cars charging system and last make sure no drain on battery parked keys out of car..
4: NO, jump fails.
check or bypass clutch switch?
this cranks ok, (bad clutch switch at its pedal.)
if still dead it can be bad key switch or bad starter relay.
lets see if it has the relay. , says yes.

so does the starter relay close, cranking?
if not fix cause that first.
it needs fuses working
it needs power to the relay contactor input
power to the coil
and the coil enabling factor the clutch depressed and its switch must be closed.
and if the antithieft box, (factory option) is unhappy
the start relay coil will be dead.
start at the relay ,
does the (turned on) dash heater fan cut off, cranked
yes, then relay is closing
no, its not. find reason.
easy with a volt meter the 4 pins on relay.
pins 3,4,5,6
12v, 12v, 0v and 12v respectively.
if the pin 5 never goes to 0v, the immoblizer is unhappy.
sorry so small, Fixya shinks it to useless....

I have grand am gt 2002 most time it starts.replace starter and new battrie. when turn the keyno power to moter I have to turn the keys on and off couple time and then it starts up any ideas on whats

Could be issue with ignition switch or security system? If the starter motor won't crank, check voltage circuits at the starter. Usually two voltage circuits, one is battery voltage, hot all the time. The other voltage comes from crank position of ignition switch. That circuit could be routed through the neutral switch or clutch switch, depending on your tranny.

Any testing at starter make sure tranny is in park or neutral and the parking brake is set.

2000 Kia Sadona...Stops from time to time. Usually when coming to a stop or taking off. Replaced fuel pump. Sometimes difficult for engine to turn over. New battery. Once I moved electrical connector...

Sounds like a possible crankshaft position sensor. It is located behind the harmonic balancer, inside the timing cover. It sets by the timing belt, so if you have a loose timing belt it could hit the crank sensor or throw up pieces of itself onto the crank sensor. A bad crank sensor can mimic a fuel pump issue. 721c6cee-d9f3-4086-a166-f472fa0318af.gif

I have a 1997 Tahoe which will not even turn over, when the weather is wet, it will sometimes fire up. I recently replaced the Crank position sensor, but the "no crank" has been an issue for some time, it...

Sounds like time for ignition switch. Don't hang a lot of trinkets and keys from your key ring. 2 keys at the most. I don't get the crank position sensor. I have never seen one go bad and has nothing to do with cranking the engine.

My 2001 deville will start ok sometimes and then other times it will not turn over for a few minutes then it will start? Why?

If the engine fails to crank sometimes, you would need to have someone check for voltage at the starter when it fails to crank.
Could be the starter or several other things including the neutral safety switch or the key switch.

1992 tracker will not start charged battery lites come on but will not turn engine ovr

The power for the starter solenoid goes thru the key switch then thru a clutch switch before getting to the starter. You would need to check the key switch and clutch switch, also check the ground and battery cables. It takes about 10 times the power to crank as anything else.
