Engine cut out shortly after start-up and then ignition failed to work

P0500 Code: Vehicle Speed Sensor 'A' Malfunction [Location] (axlewise.com)

Check the cap on the fuel tank as sometime they fail and wont let air back into the tank as fuel is used. The vehicle will run for a while hen cut out as a vacuum form in the tank After it has been stopped for while air leaks back into the tank it will start and run for a short time

yes,CRANKSHAFT SENSOR

When a crankshaft sensor has failed or is failing, certain timing problems will arise in engine function. The engine may start normally in some cases, but will cut off after a few minutes (or seconds) of operation. More than likely the engine will be unable to start at all. Since the crankshaft sensor is responsible for engine timing, the driver may experience engine backfire or irregular rpm function, if the vehicle starts at all.

Drain fluid into a clean plastic bowl, check for brass cuttings or metal shavings in sunlight. If present get complete trans overhaul.

If you are dealing with the anti theft the anti theft will flash as you are trying to start the vehicle if this is the case then it is the anti theft if not then you are not dealing with a ant theft issue. You can do a 30 minute relearn procedure without a scan tool. here is how Turn ignition on without the engine reunning.attempt to start the vehicle then release the key to ON.(vehicle doest start) Observe the security light.afeter 10 minutes the security light will turn off.Turn off the ignition and wait 5 seconds.do this 3 times for 30 minutes. start the engine with the engine started the vehicle will learn the passlock key.

takes a long time to run the rediness test since there are 6 different tests to complete...

is there power at the coil's electrical connector(key must be set to ON? Is some of your warning lights not lit(that normally light-up when key is on) such as airbag, abs, engine, battery etc??? If you answer yes to any of this, your ignition switch has failed. Acura/Honda models 97-02 have a recall on this in 2002 approx 1.5million vehicles affected. Symtoms include, intermitted speedometer/tach fluctuating to zero while car is in motion, intermitted stalling or no start(symtoms increase in hotter weather). The electrical contacts on these ignition switches are faulty causing shorts and archs within. Therefore power supply to vital engine electrical components are cut off. If this is the case, call your local Acura/Honda dealer with your vin# at hand, your vehicle may qualify for a free repair. Hopefully this helps....please rate thanks!!

I have helped many Honda/Acura owners on this issue. Many mechanics will replace many parts prior to solving this problem, which then creates unnecessary repairs and spending. So here is my diagnosis: Notice if your speedometer drops to zero when your engine dies while driving. If this happens its your ignition switch failing. Ignition switches in Honda/Acura vehicles years 97-02 encounter faulty or shorted internal contacts. This causes premateur electrical failure to vital engine electrical parts, causing vehicle to stall intermittedly. A recall has been in place since 2002, approximately 1.3mil vehicles are affected, call your local honda/acura dealer for info and possible free repair or replace the ignition switch yourself. Hopefully my info helps you!!

Here is a list of possible causes. You should not drive the vehicle if the check engine light is flashing all the time, you can cause even more damage. It could pay to have a professional find the real cause.

Spark plugs that are incorrect for the application, cracked, improperly gaped or worn can cause the engine to misfire or run rough at all times.
An IC module that failed to correctly control the ignition coil(s) will cause the engine to misfire or run rough at all times.
Poor connections, broken wiring or wiring that has shorts to ground can cause the engine to misfire or run rough at all times. NOTE: Check connectors that might be pulled apart as the engine flexes or wires that short to ground as they pass near brackets or shorts to ground on the exhaust manifold.
Fuel injector(s) that are shorted, plugged or partially restricted can cause the engine to misfire or run rough at all times.
An ignition coil(s) that has low output, corrosion on the coil tower(s), is carbon tracked or arcs to ground will cause the engine to misfire or run rough at all times.
A PCM that failed to properly control the injector or ignition timing will cause the engine to misfire or run rough at all times.

This is caused by by a bad ignition switch. According to the dealer the ignition switch contains an antenna that many of the sensors use to communicate with the vehicle, as well as the key fob. When the switch starts going bad the vehicle computer losses communication with these sensors and starts producing codes which include the 4wd and the electronic brakes. My fiance has had the same issues with her Grand Cherokee as well as the key fob not working, the remote start not working, the service engine light comes on, the door chime will sound when the key is NOT in the ignition and the lights are NOT on, as well as numerous codes usually relating to loss of communication with one system or another. All of which are fixed once the ignition switch is replaced. Unfortunately, this usually only fixes the problem for a short time (weeks or maybe a few months) before the piece of junk ignition switch fails again and it all starts over.
