I REPLACED MY OLD CAMSHAFT SENCOR MY 2002 FORD WINDSTAR. WONT START WHAT DO I DO?

I REPLACED MY CAMSHAFT SECOR ON MY 2002 FORD WINDSTAR BUT IT WONT TURN OVER DO I NEED TO BUY ANOTHER ONE .
Experienced mechanics share their insights in answering this question :
If you simply pulled out the old camshaft synchronizer and put it back in or pulled off the synchronizer, replaced the senor and put the assembly back into the engine, you did not perform the service correctly and the ignition timing is now incorrect. There is a procedure that needs to be done in a specific order including having the engine in the proper position in order to install the part in the proper timing. Consider hring an experienced technician like one from YourMechanic who can come out and correct the installation to correct your no start situation.

How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

The most common failure is the crankshaft position sensor. These fail much more frequently than the cam sensor and will cause a no start. It can also occur if the timing belt broke or jumped a tooth. I would do a compression test also to see if there is low compression.
Unfortunately, there`s no way to reset a camshaft position sensor. If you`re having camshaft issues (check engine light on, acceleration trouble, sputtering and stalling, etc.), you`ll have to replace the part entirely.
After you`ve replaced the camshaft sensor, be sure to take your car to a qualified mechanic and ask them to reprogram it using a OBD-II scanner. Doing so will clear any error codes and make sure that the engine computer is getting accurate signals from the new sensor.
While the new sensor is now installed, and you may get lucky and have it function perfectly right from the start, it`s highly recommended to “relearn” the sensor at this point in order to calibrate the entire system properly.
Evidently, you cannot reset a camshaft position sensor. Therefore, you will need to replace the component if your camshaft malfunctions (check engine light on, acceleration issues, sputtering and stalling, etc.).
NOT PERFORMING A RELEARN PROCESS

In rare cases the engine may misfire or go into “reduced power” or “limp mode” especially under high RPM/load situations Additionally, omission of the relearn process could cause the vehicle to be unable to pass an emissions test due to incomplete or failed misfire monitor.

Reasons for failure of the camshaft sensor can be: Mechanical damage. Break in the encoder wheel. Internal short circuits.
Once you install your new camshaft, you may need to go through a break-in procedure, depending on what the manufacturer recommends. This can be quite an extensive job for some vehicles – and if you do it incorrectly, engine damage can occur.
Error code P0340 indicates a malfunction with the camshaft position sensor A circuit. This type of malfunction can cause serious issues that require immediate repair because the underlying cause of the code could damage your vehicle`s engine if you continue to drive it.
You don`t need to reset it, once the engine turns over it will send the information to the ECM and the ECM will be ready to start the engine.
OBD2 Diagnostic Trouble Code P0340 indicates that the Camshaft Position Sensor `A` Circuit Malfunction in Bank 1 has been detected. The camshaft position sensor (CMP sensor) provides information regarding the rotational speed of the camshaft and where the camshaft is positioned in relationship to the crankshaft.
This can cost anywhere from $200 to $400.
Acceleration problems

If the sensor is awry it will send the wrong information into your car`s on-board computer, resulting in the inability of your engine operating system to sync the engine pistons together. This causes poor acceleration and makes your car fail to maintain constant speed.

The camshaft sensor enables the engine control to determine the exact position of the crankshaft drive. This information is required to calculate the ignition point and injection point, among other things.
Autel TS601 TPMS scan tool integrate tire pressure sensor Diagnostics(Check), Activation(Read), Programming, and Relearn in one.
If the car cranks when you turn the key, but the engine won`t start, it could be because fuel isn`t getting to the engine. One potential reason for this could be dirty fuel injectors. Over time, the fuel injector nozzles can become clogged with rust, corrosion or debris.
Dead car battery: A dead battery is the most common reason why a car won`t start. If you have a battery tester, check your battery to see if it`s weak. If you don`t have one, try to jump start your car with jumper cables.
Slowly accelerate the engine to 4,000 rpm (or indicated rpm for your vehicle). Hold rpm until the engine speed drops back toward idle. Release the throttle immediately once procedure is learned! Once the variation values are learned, the ECC will return engine control to the driver.
If your vehicle idles roughly, stalls frequently, has a drop in engine power, stumbles frequently, has reduced gas mileage, or accelerates slowly, these are all signs your camshaft position sensor could be failing.
Your vehicle should be equipped with four different camshaft position sensors, one for each of the engine`s camshafts. They are mounted in the front of the cylinder heads, near the camshaft actuators, across from each other.
Car Will Not Start: Over time, as the camshaft position sensor fails, the signal it sends to the engine control module weakens. When the engine no longer receives the signal, you will not be able to start your car.
The camshaft is usually driven either directly, via a toothed rubber “timing belt”` or via a steel roller “timing chain”. Gears have also occasionally been used to drive the camshaft. In some designs the camshaft also drives the distributor, oil pump, fuel pump and occasionally the power steering pump.
Low battery voltage can contribute to a MIL On condition for P0335 (Crankshaft Position Sensor Circuit) and/or P0340 (Camshaft Position Sensor Circuit) due to inconsistent rotational speed of the engine`s crankshaft.
Like desktop computers and most other electronics, disconnecting the battery cable for a short period will not fully reset your ECU due to the residual power remaining in the circuits.

Fuel pump engages. Batery good, alternator good volts, jump start helps when wont start. Temp does not matter. Intermittent?
ANSWER : Hello. Thank you for writing in. There are several reasons your vehicle may only start when jump starting. The first and most common is a build up of resistance that is causing you to need a boost of voltage to get the engine started. This may be due to poor battery cables, a bad ground connection, a poor starter solenoid, and a couple of other issues. The first thing you want to do is perform a visual inspection of the starting system. Make sure there is no corrosion build up in the battery cables. You can also check the resistance across these wires and make sure you have a solid connection between components. You then want to make sure the starter solenoid is doing its job. It is responsible for taking the small amount of electricity sent by the ignition and turning it into a huge electrical charge that is strong enough to push over the engine with the help of some gear ratios in its favor. Do some more testing, and stick to the basics before assuming its something seriously complicated.

Car won’t start – 2004 Ford Focus
ANSWER : Hi and thanks for contacting YourMechanic. Check the battery cables for more corrosion and clean them up again. You may need to put backing soda and water mixture on the terminals to clean the corrosion completely off. Make sure that the cables are tight and also tight on the starter solenoid. By rocking the vehicle back and forth and using the clutch to start the vehicle, this is an indication that the cable on the starter is either corroded or loose. If you need further assistance troubleshooting your starting system, then seek out a technician, such as one from YourMechanic, to diagnose and resolve the issue.

Vehicle won’t start, once it’s jump started it only stays running until you turn it off, then it work start again without jumping.
ANSWER : Hi there. There could be two problems here. It is possible that your battery is bad and will not take a charge from your alternator while driving. In that case every time you shut your car off you will not have enough juice to start it again. Inspect your battery – it should have at least 12.5 to 13 volts to start your car, if it doesn’t you will need to replace the battery. The second problem could be that your alternator is bad and not charging your battery, in this case you will need to replace your alternator. Both the battery and the alternator can be tested in your car. If you would like to have the car checked for you, a certified professional from YourMechanic can come to your car’s location to diagnose the starting problem and proceed with repairs.

When I start my car it doesn’t start after the jump start it started but later it didn’t and the battery was last replaced on 9/2012
ANSWER : As you may know when jump starting the car, the battery power provided is being supplied form the other car you are using to jump your car with. If the car does not start following the jump, this would suggest your battery may be dead and needs to be replaced. If the battery was last replaced in 9/2012, it is most likely time for a new battery as that is a decent amount of life for a battery.

Why does my car struggle to start every 4th to 5th time?
ANSWER : It sounds like your starting issues may be linked to a problem with air metering or fuel delivery. A clogged or malfunctioning idle air control valve may show some of the same symptoms you are describing. The idle air control valve can be stuck in a cold start position which may work well if the car has been sitting a few hours, but as the engine warms up there must be a regulation in airflow. Consider hiring an experienced technician like one from YourMechanic who can come out for a closer look at your hard start situation and offer a more personal diagnosis.

I got my serpentine belt replaced on my 2002 Q45 and now my car wont start. This never happened before. 2002 Infiniti Q45
ANSWER : Argh! These are scenarios that make most of us pull our hair out! Is the service event related to a failure? Or was the failure waiting to happen "the next day" anyway? It’s unlikely something was bumped, jostled or damaged while replacing the serpentine belt that would permit the car to work fine for one day, then fail the next. You don’t indicate if the "no start" appeared like a dead battery – no click, lights dim, etc. or what, if any, other symptoms were apparent. I recommend a no start inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you a trusted 2nd opinion, accurate assessment of damage and a cost estimate for repairs. This inspection will not only help you get back on your way, but the diagnostic information will help you determine if the failure was related to the service, or if higher mileage was the culprit.

put bad gas in it started to run rough then wouldn’t start. replaced clean tank out, replaced fuel pump and filter, pressure regulator
ANSWER : You may have contaminated and clogged the fuel injectors. You can try and clean the injectors if you can get it started, or you may need to replace the injectors if you cannot get it to start. Make sure the fuel pressure is checked to make sure you are getting good fuel pressures. If you want to have this looked at, a technician from YourMechanic can come to your car’s location to diagnose the starting issue, pinpoint the faulty component, and make the correct repairs.
