My apologies for hijacking this thread but jsgold and manicmechanix were good enough to respond and I wanted to follow up. Mods can advise if a new thread should be started.

Spark, fuel pressure, injector resistance and injector pulse all seem to be OK at stall. The only issue I can grab on to is various components, including the CEL, cycling off and on erratically at stall with the key in the on (not crank) position.

So replaced the CTS and this time the engine started sputtering as the fan came on and the CEL captured a code 14. I shut down the engine once I saw the CEL so I don't know yet if the engine would have stalled. Anyway, code 14 seems to be a faulty CTS circuit or ECM. I don't know if the cooling system needs checking or the thermostat needs replacing but they're not mentioned in the fault code description.

I'm going to try rewiring the CTS-ECM circuit and then I guess it's ECM replacement time unless anyone has suggestions!
