Fuel cut switch is at the back of the engine bay on the bulkhead next to the two yellow relays on the right. Its black with a round rubber top and is a push to reset. As for fuel in the vac lines and ECU, you know the score, but this time replace ALL the elbow ends, don't check, replace.wheres the fuel cutoff switch?
i think it might be to do with fuel in the Vac pipes and a poor spark.
Its not been home since it happened, at Tanvic in town, so havent been able to look at it.
Check the Oxygen sensor relay for the heater circuit, its the rellay on the right out of the two described above. if this is not working the O2 sensor will read rich at low engine speeds and idle causing the ecu to lean off the fuel. And it causes hesitation when the engine is cold.
