Jaguar xj6 1997 sport. having problems starting it in Park and neutral

now it will not start move lever back and forth in park or neutral no good ????? When you turn the key to the start position ,what happens ? Nothing ? I'am assuming this because of your statement about moving the gear selector from park to neutral . The first thing to do would be to look at wiring diagrams to see what all is involved in the starter electrical circuits . Then understanding how the electrical circuits work an then using a DVOM - digital volt ohmmeter to test the electrical circuits .

Free wiring diagrams here http://www.bbbind.com/free-tsb Enter vehicle info. Year , make , model an engine . Under system click on engine , then under subsystem click on starting . Click the search button then the blue link . Looking at the diagram I see the fuse that sends battery voltage to an through the park neutral switch to the starter relay . You can test for B+ voltage at pin 85 , if when in park you see B+ voltage there ,nothing is wrong with the park neutral switch. Pin 30 should also have battery voltage . Using a piece of 12 Gage wire , jump pin 30 & 87 , that is , where the relay plugs into in the fuse / relay box. If the starter an cables are good ,the starter will crank the engine over .

Park neutral safety switch problem ! Or transmission range sensor switch . Watch this video !
Intermittent No Crank, No Start, No Codes This is on a Honda but all cars have samething . 2006 Honda Odyssey Intermittent No Crank No Start No Codes

Transmission range sensor , through electrical signals to the PCM ,it knows what gear the vehicle is in . Some all so call it a Park neutral switch , but it does more then that . The park neutral part of it won't allow the vehicle to start unless it is in park or neutral .

there are two bolts underneath the steering column where it meets the dash. Make sure these are tight

Test/Service/Replace

The circuit on newer cars with automatic transmissions has a neutral safety, or neutral start switch installed between the ignition switch and the starter. The ignition switch cannot operate the starter motor unless the transmission is in park or neutral.
Late model vehicles with manual transmissions have a starter/clutch interlock switch that requires the clutch to be depressed to the floor.
Neutral Safety Switch
Normal operations of a neutral safety switch provides a quick check for the adjustment of the gear selector linkage.

• To do this, move the selector slowly until it clicks into the PARK position.
• Turn the ignition key to the START position.
• If the starter operates, the PARK position is correct.
• After checking the PARK position, move the lever slowly toward the NEUTRAL position until the lever drops at the end of the NEUTRAL stop in the selector gate.
• If the starter also operates at this point, the gearshift linkage is properly adjusted.
• This quick test also tests the adjustment of the neutral safety switch.
• If the engine does not start in either or both of these positions, the neutral safety switch or the gear selector linkage needs adjustment or repair.

CAUTION
Since you must work under the vehicle to adjust most shift linkages make sure you properly raise and support the vehicle before working under it. Also, wear safety glasses or goggles while working under the vehicle.
A voltmeter can be used to check the switch for voltage when the ignition key is turned to the START position with the shift lever in PARK or NEUTRAL. If there is no voltage, the switch should be adjusted or replaced.

The Neutral Safety switch monitors the position of your gear selector lever and either interrupts or allows the starting circuit in your car or truck to do its job. On newer vehicles it may also monitor the position of the brake pedal to make sure that the vehicle is in park or neutral AND that your foot is on the brake.

If your vehicle is equipped with a neutral safety switch, it should NOT start UNLESS the transmission is in Neutral or Park. On the other hand your vehicle SHOULD start when it is in Neutral or Park. If your car will start in Neutral but not in Park, you have a bad switch. Also, if your car or truck will only start by turning the key to the start position and wiggling the gear selector lever, your neutral safty switch is in need of replacement.

The nuetral safety switch is usually found near the gear shifter. If your car has the gear shift on the column, then the neutral safety switch is usully mounted on the steering column near the brake pedal. On floor mount or console mount vehicles you will find the nuetral safety switch mounted near or on the shifter mechanism.

Its sounds like the shift lever is loose at the trans, kick down lever at the same place might be your other issues. Left side of trans just above the pan is the location

It is next to the gear shift lever.

The weld on the manual lever is known to break loose. First, with the wheels off the ground, with the lever in the park position, does the drive shaft lock in park? If yes or no sometimes, drop the trans pan. I bet the nut on the lever camd loose.

Solved. Wiring to switch on foot pedal disturbed by removing footwell carpet while cleaning. This switch activates unlocking from park position of automatic gear lever. Thanks
