If it's an automatic, it has a Transmission range Switch (neutral safety switch). If it's a manual transmission, it'll have a clutch start switch. Here's the schematic:

Why once I have driven my 1998 Ford Explorer XLT and the motor warms up and I turn off the switch. The ignition will not turn over. I can. Crossout the cylinoid and it starts automatically


Hey Opie , how are thing's in Mayberry ? Ha Ha Ha , bet you get that a lot .
The ignition will not turn over. You mean the starter will not turn over ? When you turn the key to the start position nothing happens ? The starter doesn't spin the engine .
Could be a few reasons . High resistance in the starting circuits . Do you have and know how to use a volt meter ? Doing voltage drop testing on the starter motor , cables .

Installed a new ignation switch with the keys that don`t have chips. Motor turns but won`t crank. Also keys won`t come out of the ignation unless thr ignation is unplugged.


It's not going to start without receiving the right code from the chipped keys. You've only swapped out half the anti-theft system. The rest is in the software. No way to get past that. Fix it right or you'll be walkin'

Have 2005 pt cruiser full battery charge wont start


The starter motor has two voltage circuits. One comes from the battery, hot all the time. The other circuit goes hot with key in the start position and starter relay is energized. The starter motor grounds through the engine block. If voltage and ground for the starter motor are good, then I would have to check starter motor. You can use a test light to check voltage. Any testing at starter motor make sure tranny is in park or neutral and parking brake is set.

94ford probe won't start


Well Sandra , the thing to do would be to get it to turn the engine over with the key , Then diagnose the no start problem . Look at a wiring diagram (do you know what that is ?) When you turn the key to start , the electrical part of the ignition switch sends B+ voltage to the starter interrupter relay through the clutch switch to the starter motor solenoid . Testing the electrical circuit with a DVOM - digital volt ohm meter with the help of a wiring diagram ,so you know where to test is the proper way to diagnose the problem . Not guessing ,an rigging the stuff . You can find free wiring diagrams here http://www.bbbind.com/free_tsb.html

1998 Honda Accord Won't Start


Park neutral safety switch maybe be the reason for the no crank ! Try putting the vehicle in park ,then try to crank the engine . Testing the electrical circuit is the best way to trouble shoot this problem , along with do a voltage drop test on the starter circuit ! This will test the battery cables an connections .

Something that fixes there problem was just lucky guess. By you saying it won't crank i take that to mean that when you turn the key to the start position nothing happens ? Is this correct ? A lot of people get that mixed up with the vehicle won't start a run . Do you know what a wiring diagram is ? What a DVOM -digital volt ohmmeter is ? How to use them for testing a electrical circuit .
What size engine does it have ? Is it a 4X4 ? Manual or automatic transmission ?

Hi Debbie , Do you know anything about automotive electrical systems an testing ? Viewing wiring diagrams to see what all is involved in the starting system on your vehicle would be the first step ,then testing the electrical circuits for the starter using a DVOM - digital volt ohm meter .

Starter Voltage Drop
Free wiring diagrams here http://www.bbbind.com/free-tsb Enter vehicle info. Year ,make , model an engine . Under system click engine ,then under subsystem click on starting . Click the search button then the blue link. Looking at the diagram I see when the key is turned to start it send a crank signal to the PCM - engine computer , if the PCM gets a valid fuel enable & starter enable signal from the anti-theft system it will energize the crank relay sending B+ voltage to the S terminal on the starter solenoid . That is if the park neutral safety switch is OK . You mite try putting the vehicle in neutral to see if it starts then. These switch wear on the inside that could cause a no start problem . You can test from the crank relay ,watch this video VEHICLE RELAYS Operation Diagnosis In the video he uses a horn circuit , your crank relay works the same .

1998 tl 3.2 won't start. only a 'tak' sound can be heard


it culd be problem with solinoied switch of starter, or with ignation switch, to find out, when car wont start some one have to check supply at starer solinoid small nut mounted wire, if supply is there then you can go to check if any relay is there before ignation switch if relay is fine you can replace ignation switch.
