1999 Continental will not start

There are some things you can do to fix the problem. Check battery connections: Even if the batteries are charged, it is important to make sure the battery cables are clean and tightly connected. Components with loose or damaged wires can interfere with efficient energy transfer. Check fuse relays: Check the vehicle fuse box for any blown fuses or defective relays that could affect the starting system. Transmission Position Sensor: If your vehicle has an automatic transmission, the transmission position sensor (neutral safety switch) may not work properly, preventing the vehicle from starting into gear Start the vehicle in both park and neutral and check that is there any difference. Check for safety system problems: Some cars have safety systems that can shut down the engine if there is a problem. Make sure the security light on the dashboard behaves as it should and try to use a spare key if there is one. Starter Motor: The starter motor may be faulty. Turn the key and listen for the clicking sound. If you hear a rapid clicking noise, it could indicate a faulty battery or a faulty starter motor. Hearing a click once could indicate a problem with the starter solenoid. Ignition switch: The ignition switch sends power to the starter when the key is turned. If faulty, it can prevent the engine from cranking. Try to notice a change when you change the key. Fuel Supply: If the engine cranks but does not start, there may be a fuel issue. Check the fuel level and make sure the fuel pump is working properly. Check engine light: If the check engine light illuminates, a diagnostic trouble code (DTC) may be stored in the vehicle computer.

If your 1999 Nissan Bluebird is cranking but not starting, here are a few things you can check: Fuel supply: Check if there is fuel in the tank and if the fuel pump is functioning properly. You can listen for a humming sound from the fuel pump when you turn the key to the "On" position. If you don't hear anything, the fuel pump may be faulty. Spark: Check if there is a spark at the spark plugs. You can remove a spark plug, connect it to the spark plug wire, and ground the spark plug to the engine block while someone cranks the engine. If there is no spark, you may have a problem with the ignition system, such as a bad ignition coil or ignition module. Battery: Check if the battery has enough power to start the engine. You can try jump-starting the car or using a battery charger to charge the battery. Starter motor: Check if the starter motor is working properly. You can try tapping on the starter motor with a wrench or hammer while someone cranks the engine. If the engine starts, the starter motor may be faulty. Sensors: Check if any of the engine sensors, such as the crankshaft position sensor or the camshaft position sensor, are faulty. These sensors provide important information to the engine control module (ECM) to help it determine when to fire the spark plugs and inject fuel. If you are unable to identify the problem on your own, it may be best to take your vehicle to a qualified mechanic who can diagnose and repair the issue.

Do you have a check engine light, what is the code. Do You have fuel pressure. You changed the fuel pump but is your fuse and relay good to the fuel pump. When you turn the key on do you hear the fuel pump kick on. It should come on as soon as you turn the key on, not just when you try to crank it. If you have a code it would help.

Check power to starter motor and solenoid. If no power present on engine crank, then check ignition barrel, key and main fuses.If power present on cranking, but starter motor does not energize, then check starter connections and replace starter motor and solenoid if necessary.
Double check starter motor operation with starter removed from the engine. If it works, then check engine condition as this may be seized.

remove starter and have it tested at your local part store

If it doesn't crank or do nothing, check the starter and ignition fuse. If it does, check for your fuel pump kicking on. When you turn the key, you should hear it buzz for a second or two. Check fuel filter, could be clogged. If fuel checks out, it may be your distributor, which includes the rotor and cap. It may be a cam sensor or crank sensor. With so many posibilities, if you can get a code, this would be your best bet. If not, perhaps go to a junkyard where you can get these parts cheap.

IIf doesn't crank then problem with neutral safety switch, starter solenoid, starter or ignition switch. If cranks then could be bad crankshaft sensor, bad ignition coil pack, blown injector(s) but usually you will get a stall beforehand. Fuel pump could be dead, turn key to ON (not starting) and listen for a few second hum as it primes the fuel rail. Also check to see if check engine light comes on for a few second with key to ON, if not then not powering up due to shirt or bad. Possible but rarely the fuel filter is so clogged it no longer allows fuel, but usually will allow start after sitting.

I think the anti theft anewer is correct. I have an extra key for my '99 Lincoln continental that apparently doesnt have whatever "chip" it needs in it. If you try to use that key it cranks but won't start. I don't know if the key "chip" can fail or not. Maybe a quick conversation with a lock smith will shed some light on the problem.

check fuel pump relay/should run pump for two sec when key is turned on. try turning key on but dont crank did pump hum/if it did look towards leaky fuel inj./faulty pressure reg. poss clogged fuel filt.

Nate, I'm not sure what you mean when you say,"I can get it to whine but not turn over. The starter is trying to get it to turn, but I don't think it is getting any gas".

Separate and aprt from not getting any gas is the fact( if I understande you correctly) that the motor is not being cranked by the starter motor. You say "it whines". You are referring to the starter motor, right? the starter motor should not "whine". If this is what's happening by guess is the Bendix spring in the starter motor is broken. The bendix spring is a heavy spring that is mounter on s worm gear in the starter motor. When you go to start the motor by turning the key the starter motor turn and the spring travels down this worm gear and engages tthe geared flywheel and cranks the engine. As soon as the engine starts the flywheel is now turning the bendix spring faster that the starter motor and the spring kicks back to its original position. If the spring is broken it never engages the flywheel and the engine wont crank.
The fact that you say the starter "whines" is what I would expect you to hear if the starter is at fault.

As far as no fuel flow there are 2 ifs: if you have an electric fuel pump, then there is a problem in the fuel flow. If you do not have a electric pump then the fuel pump runs off of the engines motion and since the engine is not cranking, the pump is not pumping and the fuel is not flowing.

Anything else you can add before we conclude that the starter has to come off?
