P0372 p1371 car wont start and when it does only runs for about 15 minutes

If your 1997 Plymouth Breeze 2.0 is not starting and there's no spark, it is likely due to an issue with the ignition system. Here are some possible causes and solutions:

1. Faulty ignition coil: The ignition coil is responsible for supplying spark to the spark plugs. If it's faulty, there will be no spark. A mechanic can test the ignition coil and replace it if necessary.

2. Bad spark plugs: Worn or faulty spark plugs can also prevent the engine from starting. Check the spark plugs for any signs of wear or damage and replace them if needed.

3. Failed crankshaft position sensor: The crankshaft position sensor is responsible for providing the ECU with information about the position of the crankshaft. If it fails, the ECU won't be able to send a signal to the ignition coil to fire. Check the sensor and replace if necessary.

4. Failed ignition switch: If the ignition switch fails, the ECU won't receive the signal to send power to the ignition coil, and there will be no spark. A mechanic can check the ignition switch and replace it if needed.

I suggest taking your car to a qualified mechanic to properly diagnose and fix the issue.

What make vehicle ? year an model too ! Before you replaced those parts did you check for battery supply voltage an check the ground for those components ? You need to get a wiring diagram an see what get's voltage an what is ground ! An see what all is involved , crankshaft position sensor , ECM / PCM -engine computer etc...! Then you need a DVOM - digital volt ohm meter to test ! Your looking for a quick fix an doesn't work like that !

A bad Coil , ignition control module , crankshaft position sensor ,no voltage to the ignition system ! No Start No Spark Cranks OK GMC Jimmy S10 Blazer

This can happen when an electrical part gets warmed up and fails. Possible causes are the fuel pump, the ignition coil, ignition control module (or igniter as Honda calls it), crankshaft position sensor to name the most common. The first causes a fuel problem, the last three are ignition related and cause loss of spark at the spark plugs. What you could do is check for spark on one of the spark plug wires while someone cranks the engine over, immediately after it shuts off and won't restart. If you have no spark, then you know it is ignition related. If you do still have spark, it could be your fuel pump. The best check for that is to check the fuel pressure with a fuel pressure gauge.

check the connection at the crankshaft pos sensor... did the car do this befor you started working on it ?

Hi, these codes relate to the crankshaft position sensor. Recommend you check the sensor to make sure it is tight and the connector is fully on. If it looks in order, consider replacing the sensor. If you reply with your model and year, I will see if I can provide additional information.

P0335 Crankshaft position (CKP) sensor - circuit malfunction
Possible causes: Wiring, CKP sensor, ECM

P0372 Timing reference, high resolution signal A - too few pulses
Possible causes: Wiring, CKP/RPM/CMP sensor, ECM

First check power to the coil. Pull the connector off and probe the connector terminal from the pink wire with a 12 volt test light. Connect the test light clip to a ground point/bolt on the engine. The test light should come on when the ignition switch is on. If not, suspect the ECM-1 fuse is bad or the ignition switch is bad.
If there is power to the coil, next test the coil. Run a jumper from the battery positive terminal to the pink terminal on the coil itself. Pull the coil wire off the distributor and place the wire close (within 1/4 inch) to a ground point on the engine. Then, briefly touch a jumper from the black/white coil terminal to engine ground. The coil should release a spark. If not, replace the coil.
If the coil is good, suspect the crankshaft position sensor is bad or loose. I'm assuming your engine light is off, but the sensor can fail without setting the engine light. If the engine light is on, see if you can get a scan to see if a crankshaft sensor trouble code is set.
Please let me know if you have any questions.

replace the crankshaft position sensor, it will cure the problem.

sounds like coil problem, coils will start cold then get hot and stop. when coil cools will crank up and run till it gets hot, try to replace the ignition coil,dont think it would be a crank sensor, try a coil,thanks robert b.

Had any check engine lights come on before you made any changes?
The ignition system uses an ignition coil, crankshaft and camshaft angle sensor along with the car's computer or PCM (power control module). This system can stop working due to a failed ignition module or crankshaft angle sensor.
Testing the ignition system is an easy job that takes about five minutes and can be done using a test light or an extra spark plug. Connect a test light to ground and with one of the spark plug wires or coils disconnected. Crank the engine over while holding the tip of the test light about 1/4 inch from the wire or coil terminal. Keep your hands clear of the test area to avoid accidental shock (non lethal). You can also insert a spark plug into the coil or wire and hold it against a metal ground. You should see a light blue spark in the gap .. which tells you the system is working. If no spark is present suspect that the crankshaft sensor needs replacing which is the most common problem.
But you could also check your relay/fuse box and see if any ignition related relays are bad. One way to check a bad relay is to find another one in the box that is exactly the same ans switch them ... and see what happens.

Good luck on your troubleshooting
