My 2001 pt shut off while i was driving i changed the coil,battery,the gas line and pump and it still wont start??

This would be pointing to the wrong fuel being filled up.
Drain the fuel tank, flush the system, change the filter and re-fill with correct fuel.

Did u check for codes? On pt cruisers the odometer will read out a trouble code if the computer detects a problem with coil, spark etc. If ur checking to see if fuel pump comes on turn ignition on. You shpuld be able to hear fuel pump run for a few seconds and relays click on to start vehicle.

So many possibilities and you need to do some narrowing and less parts replacement. Check fuel pressure AND see if the pressure drops off. The pressure shouldn't drop off when you shut the engine off. Are there any codes or engine lights on? I just had a PT come in and the cel bulb had been disable. After reading the code I could fix the problem. If the plugs are swimming you will have a code. If only one plug then maybe not.

have you changed the fuel filter?

Sounds like the coil is bad see if you have spark when it wont start

OK, the starter turns the engine over, and you can hear (?) the fuel pump. Check
* is there any spark? Use a timing light to check. If no spark, then the spark generation system (coil(s), igniter or other) is not working.

If there is spark, then pull the timing belt covers and check that you have not slipped a few teeth. If the PT has an interference engine (as I suspect), you may have bent some valves.

If the timing belt is OK, do a compression test.

When you turn on the ignition, does the Check Engine light flash then turn off? Could be a failing / failed ECU.

put a air line onto fuel line and blow it back to tank change your inline filter and rebleed the system if it still wont go check your fuel pump hope this helps

when you pump the gas, you shut off the fuel injectors. could have one leaking causing it to flood and not start

Could be failed fuel pump. Disconnect fuel line at engine and turn over a couple times having something to catch gas in. If electric pump don't turn over engine, just turn key to run position for a few seconds. Maybe clogged fuel filter or faulty pump if no gas shows. Change fuel filter and try again. If none, change pump.

Hi again,

Would appreciate a feedback for any developments (or even the lack of it).

Cheers.
