Engine Stalling Once Its Up To Temperature

[kentguy17]

HI

I am currently having issues with my Lexus IS200 1999. When the car is cold she will start and run for about 10-20 mins until she is up to running temperature then she will just stall. She will start again no problem but will just stall straight away. If you leave her to go cold again she will start again and run for 10-20 mins and then again stall. The engine light and the TRC flashing lights come on. I was wondering if anybody else have had the same problem and what they did to resolve? Any information would be greatly appreciated. Crankshaft sensor? Possibly? it is definitely an electrical fault as the engine sounds good and and gear box and clutch all work ok.

Hi mate im not sure of the cause of the stalling. But a good start would be to get yourself a code reader for about £10 from eBay. They can tell you what the fault code is and from there you can look into what the problem could be.

I see your from Kent, where abouts im from Chatham.

Hi Dean,

The code is P1300 ignitor circuit.

have a look at this thread:

Try taking engine plastics off and removing the coilpacks, unbolt them lift them out a little just so they resting on top of the spark plugs, run the car and one by one lift the coilpacks out seeing if you can hear them sparking / clicking from the ignitor in the coilpack to the spark plug. At least one of them should not spark, there's your problem. Might be one or two of them not sparking. Give that a try and see how you get on.

Hi Dean

The coil packs are all working correctly, sparking etc and no misfires and all the wiring to the coils packs look good. The only sensor we have not managed to look at yet is the crankshaft sensor, The ECM uses input signals from the pick up devices( Camshaft and crankshaft positioning sensors) to switch the ignition coils primary circuits on or off.

If there was a problem with the coil packs, surely it would be obvious when the car runs even when cold? there's no misfires and the engine sounds good until it gets up to temperature then stalls and wont run again until she goes cold.
