Troubleshooting Pt Cruiser Cranks But Won’t Start: A Step-by-Step Guide

The most likely cause of a Pt Cruiser not starting when cranking is a faulty fuel delivery system.

Pt Cruiser Cranks But Wont Start

If your Chrysler PT Cruiser won’t start, even though the engine is cranking, it can be incredibly frustrating to figure out. Figuring out why a car cranks but wont start is a multi-step process that involves checking the battery, starter and fuel system. Many of these components are linked together, so if one part fails, you’ll need to diagnose each component individually in order to get your car up and running again. In this guide, we will examine the key components involved in a PT Cruiser’s starting system in order to help you find the issue with your vehicle and how to fix it. With our help and some basic tools you should be able to diagnose your PT Cruiser and get it started again in no time.

Crank Sensor Issues

The crank sensor is an essential component in the ignition system of your Chrysler PT Cruiser. It is responsible for monitoring the engine’s revolutions per minute (RPM) and sending a signal to the ignition system to fire the spark plugs at the right time. If there is a problem with the crank sensor, it can cause your PT Cruiser to crank but not start. Symptoms of a faulty crank sensor include: engine misfires, rough idling, stalling, and difficulty starting.

Troubleshooting a faulty crank sensor involves checking for power and ground at the sensor, as well as checking its resistance. To test for power and ground, use a multimeter to measure the voltage on both power and ground pins on the connector. You should see between 9-12 volts when testing. If there is no power or ground present, then you may have an issue with either your battery or alternator.

To check the resistance of your crank sensor, use an ohmmeter to measure it while it is disconnected from the vehicle. Most sensors will have a resistance reading of between 500-1300 ohms when cold. If your reading is outside that range, then you may need to replace your crank sensor.

Battery Checks

If your Chrysler PT Cruiser cranks but won’t start, one of the first things you should check is your battery. Testing your battery can help determine if it has enough power to start up your vehicle. To test it, you’ll need a multimeter or battery tester that can measure voltage and current draw from your battery terminals. With these tools in hand, you can measure how much charge is left in your battery and see if it has enough juice for successful start-up.

You should also inspect any corroded connections around the terminals or cables that could be causing problems with power delivery to the starter motor or other components in the engine control system. Corroded connections can be cleaned using baking soda and water solution or by using a wire brush and some electrical contact cleaner spray to get rid of any corrosion buildup on metal surfaces near those connections.

Alternator Problems

Another common cause of cranking but not starting issues in Chrysler PT Cruisers are alternator problems. The alternator is responsible for generating electrical current for various components in order for them to function properly – including engine control systems such as fuel injectors and spark plugs as well as charging batteries so that they can supply enough energy for starting up engines successfully when needed. Signs of an alternator failure include dim headlights or dashboard lights due to lack of voltage being produced by this component as well as dashboard warning lights such as ‘Battery’ or ‘Check Engine’.

Diagnosing alternator problems involves running tests on its output voltage while connected directly to its terminals using either a multimeter or specialized digital voltmeter made specifically for this purpose (such as those found at auto parts stores). The readings should typically read between 13-15 volts depending on engine speed – if they don’t then you may need to replace this component altogether so that other systems relying on its output are able to function properly again without issue while also ensuring sufficient charge levels in batteries so they can supply enough juice when needed during vehicle start-up attempts down the line without any further issues arising due to insufficient charge levels caused by weak output from said alternator unit itself..

Spark Plugs And Wires

Another common cause behind cranking but no starting issues in Chrysler PT Cruisers are faulty spark plugs and their accompanying wires which connect them directly with their respective cylinders inside engines themselves during combustion cycles where energy created from said combustion process propels pistons inside those cylinders up and down resulting in movement which then gets translated into rotation via crankshaft in order for wheels attached at other end via transmission system move forward thus enabling vehicles powered by internal combustion engines such as said Chrysler PT Cruiser move forward under their own propulsion without needing any external assistance like pushing etc..

Checking these components involves inspecting each spark plug wire’s insulation covering along length of said wire itself looking out any visible signs damage caused by age related wear tear over time resulting possible short circuits thus causing misfiring among other problems thereby potentially leading cranking but no starting issues inside vehicles like aforementioned Chrysler PT Cruiser example..

If you find any signs damage along insulation covering said wires themselves then best course action replace all spark plug wires associated cylinders order ensure correct functioning combustion cycles taking place within those cylinders thus providing necessary amount energy required move pistons up down rotation via crankshaft onto wheels thus enabling vehicle powered internal combustion engine move forward under own propulsion without needing external assistance pushing etc…

Fuel Pump Check

When troubleshooting a Pt Cruiser that cranks but won’t start, it is important to check the fuel pump. The first step is to manually check the fuel pump relay and fuse. An easy way to do this is by locating the fuse box in the car and checking for any blown fuses or other damage. If all looks well, then it is time to examine pressure with a fuel pressure gauge. This will tell you if there is an issue with the fuel pump not being able to pressurize the fuel lines properly.

Clogged Fuel Filters

Another potential cause of a Pt Cruiser cranking but not starting could be clogged fuel filters. To identify this problem, you will need to perform an internal combustion engine diagnostic test. This test will tell you if there are any blockages in your fuel system that are preventing your car from starting up properly. If this is the case, then it may be necessary to replace your fuel filter in order to get your car running again.

Starter Motor Checks

If neither of these solutions solve your problem, then it may be necessary to check your starter motor. There are certain symptoms that can indicate a faulty starter motor such as grinding noises when attempting to start the vehicle or slow cranking speed when attempting to turn over the engine. If these symptoms are present, then it is best to take your car into an auto repair shop and have them perform a starter motor test on your vehicle in order to determine what needs repairing or replacing.

Poor Compression In Cylinders

Another issue that could be causing a Pt Cruiser cranks but wont start problem is poor compression in its cylinders. Compression plays an important role in internal combustion engines because it allows for proper combustion of gasoline and air mixture which then creates power for starting up a vehicles engine. If compression levels are too low due to worn out piston rings or other issues, then it can prevent an engine from functioning correctly and result in a crank but no start situation. Troubleshooting this issue can involve performing leak down tests on each cylinder or doing pressure tests on each cylinder head individually in order to identify where any potential problems may be coming from so they can be repaired accordingly.
