My 2001 Jeep Grand Cherokee wont start sometimes, but if I put it in neutral then try to start it..It starts .. What is the problem with my baby.......


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.

My 2002 tbird won't get out ofnpark


If you cannot move the gearshift lever out of P (Park) with ignition in
the RUN position and the brake pedal depressed:
1. Apply the parking brake, turn ignition key to LOCK, then remove the
key.
2. Insert the key and turn it to OFF. Apply the brake pedal and shift to N
(Neutral). This allows the automatic transmission shift lever to be
moved from the P (Park) position without the brake pedal
depressed.
3. Start the vehicle.
If it is necessary to use the above procedure to move the gearshift lever,
it is possible that a fuse has blown or the vehicle's brakelamps are not
operating properly.

1995 ford ranger wont come out of park


try disconnecting the rods from the ignition switch shift lever inhibitor.this is basically the mechanism which prevents you from turning the ignition switch to the 'lock' position when the shift lever is not in the 'park' position

Steering wheel wont lock and stuck in park


In the fuse block under the drivers side rear seat check the ignition 0 fuse. In the under hood fuse block check the B/U fuse and the BTSI fuse. If the b/u fuse is blown than you would not have back up lamps.

Starter wont turn over


It would help a whole lot if you could describe the problem with more information. Do any of the lights on the car work? Do you hear any noise when you attempt to start car?
Try moving the gear shifter out of Park position and then back again a few times. Turn the key to the start position a few times.
Problem could be a bad ignition switch, neutral safety switch, starter or starter relay (located in underhood fuse box, #47 relay)

Tachometer stopped working then the speedometer now the service engine comes on randomly and there is a strange noise when starting the blazer and sometimes it almost seems as though it is not going to...


The speedometer and tachometer problem on your Trailblazer instrument cluster is very common on the 03-06 models. It's caused by failing stepper motors on the cluster's circuit board and can be fixed. Check out this page for more on how to get it fixed - Trailblazer tachometer problems
