2011 Jeep Compass Limited had crank position sensor issue before repaired and was fine did not replace that harness that goes to it but now issue seems the same as ignition switch stays on while trying to start it and ran Diagnostics and iat sensor circuit read high input and also oil temp sensor circuit also read high input.
Recharge the battery after trying to start it this time initially but nothing came on at all this time

My car has 135000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
If the check engine light is on, a check engine light diagnostic, performed by a certified mechanic from YourMechanic, will resolve any codes that are currently being reported that could be the cause of the no start condition (obviously, you want to simply get the car running first, so if a code has set that implicates, for example, a loose gas cap, that is initially ignored but you come back to it later).

With regard to the no start condition, if the resolution of relevant trouble codes does not resolve that, it is a standard diagnostic. Of course, confirm that the engine immobilizer system (security system) is not activated thus preventing the car from starting. Prior to performing circuit diagnostics be sure you have a fully charged battery that passes a load test. If the starter motor is turning the engine over rapidly, at sufficient RPM, but the engine does not catch and run, that means that there is an ignition, fuel or air induction fault in the engine that will have to be repaired. To obtain a diagnose and repair of the fault, the service to request is a no start diagnostic. If there is no starter motor operation at all, that is if there is no starter operation with the key held in the "start" position, the procedure is to test for power to the starter motor. If there is no power, then the electrical circuit supplying the motor has a fault. That circuit begins at the battery and includes grounds, wiring (some of which is very heavy cabling), fuses, relays, the ignition switch and terminations. Basically, with a fully charged battery, and with the key held in the "start" position, the starter is either getting power or it isn’t. With the key in the "start" position, if the starter motor is getting power but the starter doesn’t work, then the starter is condemned and replaced. If you desire that a certified mechanic resolve this, please simply request a no start diagnostic and the responding certified mechanic will get the problem diagnosed and repaired for you.

How to Identify and Fix Common car Problems ?

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

The most common causes for a Jeep failing to start despite its radio and lights working are issues relating to its battery or other cranking/start-up components, such as the ignition switch, starter, or spark plug. These pieces might be damaged, dirty, or corroded.
The most common reasons a Jeep Wrangler won`t start are a dead battery, an alternator problem, or failed starter. Search our network of RepairPal Certified shops near you to speak with a technician about your issue.
Engine Misfires or Vibrates

A failing crankshaft position sensor cannot provide the right information about piston positioning in the engine, causing a cylinder to misfire. This could also occur from faulty spark plug timing, but if the spark plug checks out, then the crankshaft sensor is likely the source.

The Crankshaft Position sensor is normally located in the timing cover or on the side of the block with a cylindrical portion that inserts into the block.
The Crank position sensor is usually mounted in the crankcase over the toothed wheel on the crankshaft. The Camshaft position sensor is usually mounted in line with the toothed wheel on the end of the camshaft. It is usually hidden under the timing chain cover on the front of the engine.
The most common problems include transmission issues, powertrain issues, suspension issues, steering issues and poor fueld economy.

My truck won’t start. I put a new fuel pump, cam shaft sensor, cleaned my crank sensor, and put a new battery in it. It will crank but not start.
ANSWER : Check the exhaust system for any leaks before the oxygen sensors. This can contribute to having more oxygen in the exhaust stream causing the sensors to register a false reading. If there is no leaks in the exhaust, then check the engine for any vacuum leaks. Look at all of the vacuum lines, the intake gaskets, and the brake booster. A vacuum leak will cause the engine idle to accelerate fast and also cause the engine to stall when the computer brings the idle down. If you need further assistance with your engine stalling, then seek out a professional, such as one from Your Mechanic, to help you.

I put in a new starter and battery and my Jeep will not start. Please help me get my Jeep to start.
ANSWER : Hi there. Check to see if the wiring to the battery and the starter are tight and clean. A bad connection will cause a no start situation. If the battery cables and wires are all tight and clean, then go in the cab and turn on the ignition switch and see if any thing in the cab works.

If nothing comes on, then check the fuse box for any blown fuses. If all the fuse are good in the cab and under the hood, then the ignition switch needs replaced. If the ignition switch is good and the accessories come on, then either the starter relay in the fuse box has failed or the wires from the starter relay to the ignition switch has become burned or loose. Check the wires from the starter relay on the starter to the ignition switch. If everything checks out to be good, then the ignition switch needs replaced.

I put new throttle position sensor on now the car wont start i connected everything back on correctly so why wont it crank now ?
ANSWER : Hey there. Replacement of the throttle position sensor on your vehicle is pretty straight forward. There is no adjustment to be made – just remove and replace the sensor and you should be done. If the vehicle isn’t starting, you left something disconnected or there is a separate issue all together. If all of the work has been double checked and you still can’t get to the bottom of it then it is likely another problem that is occurring that is causing it to fail. You’ll want to see if the computer is still indicating a bad sensor even with the new one on. There are other sensors that could be causing the car to go into limp mode, such as a problem with the fuel system or another sensor on the vehicle. I recommend having another expert diagnose the starting problem so that this can be addressed properly.

My car cranks but will not start. I try to do fix the car myself. I put new battery, new alternator, and new ignition coils.
ANSWER : Hi there. Check the spark plugs and see if they are worn or burned. If the plugs are good and they have a good spark, then the engine compression could be low causing a no start situation. If the spark plugs are not emitting a spark, then the crankshaft position sensor could have failed or disconnected. Check the crankshaft position sensor wiring harness and make sure that its plugged in. Check the sensor and make sure that its not broken or damaged. If you need further assistance with your engine not starting, then seek out a professional, such as one from Your Mechanic, to help you.

Cranks over start than dies
ANSWER : Hi There,
The idle air control valve is a small valve on the engine’s intake system that reads the air intake as it comes into the motor. This is controlled by the car’s ECM which uses this information to make adjustments to the air/fuel ratio depending on various inputs such as outside air temperature, intake air temperature, load and various other things. As you accelerate, your car’s engine is receiving a much higher dose of fuel than when at idle and conversely, when you let off the gas pedal, there is a sudden change in this fuel supply as a result of your foot letting off the pedal. When this happens, the job of the idle air control valve is to bring this deceleration down to a slow and smooth idle rather than suddenly cutting off the fuel supply causing the motor to die. When the idle air control valve is not working properly, this cause a disruption in this process resulting in the engine not being able to idle properly. I would recommend having a professional come to your location to diagnose and inspect your vehicle.

When I try to start it, it cranks slowly as in cranks like dead battery but then cranks just fine but won’t start
ANSWER : Hello, and thank you for writing in. To begin there may be issues with the wiring, position of the starter, a faulty starter, or an issue with the timing. However start with the simplest options and work you way up in complication. With replacement starters, it is often required to add a shim to the mount in order to align the starter correctly. If the gears are misaligned, or not making good contact, then the starter motor will bind or move slower. This may even result in a grinding. Secondly with a voltmeter you can test the voltage available to the starter and see if it is receiving the full 12 volts. If it is not, then you may have a bad wire, a loose connection, a dirty connection, an issue with the starting system, or a bad ground. If it is, then you want to look deeper into the alignment of the starter, and check if it was a re-manufactured replacement part. After you rule out a faulty starter you can then resort to the timing and other sensors. For more diagnostic help, contact our service department to schedule an appointment.

check engine light code said replace cam sensor will not crank with new sensor but wiil crank with old sensor
ANSWER : Hi there:

That is a very off symptom you’re describing. Without being there to phyisicaly inspect your Nissan, the only thing I’d guess that might be causing this is if the cam sensor you installed was the incorrect one, or perhaps the electrical harness created an electrical fault; causing the ignition relay to not send a signal to the starter relay. You might want to have a professional mobile mechanic complete a car is hard to start inspection; so they can determine why you’re having this issue.
