I have a 2002 pt cruiser touring. I was driving and the oil light came on and then the car slowed down and died on me. It won't start and it sunds like it wonts to but it won't and the oil light stays on. What could this be???

Sound like low engine compression
head gasket gone between the cyl

check the fuses and put a scan tool on it to check for any codes

My PT did that when my timing belt broke. It cost $500.00 to replace it. If it is broken, be ready to have some motor work done. I had to have to values replaced at a cost of $900.00. If your timing belt is not broken then check the alternator and battery. I was riding down the road and my PT shut all the way down and would not start. I had to leave it beside the road. It was my alternator. It gave me no warning.

Check your electric radiator cooling fan I have replaced them for seizing up. If it can'nt cool the radiator car will overheat.

this obd2 trouble code table can help u understand the meaning of code.
po522, the possible solution:
The most likely cause is a faulty oil pressure sensor/switch.
for p0688, you can Check all the ECM fuses, if the fuses are OK try replacing the ASD relay.

Change the coil pack if your getting No spark.Or the crankshaft sensor.

There are 2 possibilities. It is on Power distribution Center (mine was there)
or Fuse Block

If you like to fix your fog lights, you must replace malfunction switch. It is a typically PT-Cruiser problem.

Probably blowed it. Sorry to say. You can continue to crank it but it probably already seized a bearing. Run a pressure check on the oil.

Sounds as if the alternator is not charging the battery. Check the alternator for voltage it should put out around 13 volts at idle and normal operation. If it charges then the battery is defective. A good place to start is clean the battery cables to remove any corrosion and make good contact. Many an electrical problem has been solved by cleaning battery cables.
