Starting and Stopping Procedure and how to prevent Flooding

Post by Will66 » Sat Apr 19, 2014 12:09 pm

Right, since there seems to be a great deal of machinations about this and some confusion about what needs to happen I thought I would lay a procedure that has worked for me for the last 7 years and 75k of RX8 ownership and never flooding it once!

Starting your RX8:

Sit in the driver's seat of your RX8 with the gearbox in neutral, you can put your foot on the clutch if you want but it shouldn't make much difference.

Turn your key to position II.

Wait until the self-test lights for the airbags and the DSC etc have gone out, this gives the fuel pump time to prime the fuel rails and should mean less cranking.

Turn the key to position III and crank until the engine fires. It should only take a second or two to fire up hot or cold. It can take a little longer if the engine has cooled significantly from normal running temperature but hasn't got back to ambient temperature. It shouldn't take longer than 10 seconds and if it does you may have other problems.

Once it's running you can drive off immediately, on exceptionally cold days it may be worth waiting for 30 seconds before moving off but this is a very rare occurrence, -10ºC or below.

On a cold start the engine will fast idle at 2500 rpm initially but this will drop to around 800 rpm over a few minutes.

Stopping your RX8:

Stop the car, handbrake on, gearbox in neutral, engine at idle.

Turn the key to position I. From there you can turn the key to position 0 and remove it and then do whatever you want.

Emergency Procedure to prevent cold start flooding:

THIS PROCEDURE SHOULD ONLY BE USED IF THE CAR HAS TO BE SHUT DOWN WHEN THE ENGINE IS STILL FAST IDLING ON A COLD START ABOVE 2000 RPM.

You can employ it if the motor is still idling above 1500 rpm but it shouldn't be necessary.

Prior to turning off the engine, hold the RPM at 4000 rpm using the throttle, maintaining throttle pressure required to keep these rpm, switch the key to position I.

DO NOT USE THIS PROCEDURE DURING A SHUTDOWN WHEN THE ENGINE IS IDLING BELOW 1500 RPM.

Doing this procedure is detrimental to the health of the engine and should be avoided if at all possible, it washes out lubricating oil from the rotor housings and can increase engine wear, it will also flush any unburnt fuel into the catalytic converter which could shorten its life.

Anyone who tells you that you should rev your RX8 to 4000 rpm every time you shut it down is, quite frankly, foolish and ignorant.

:whathesaid:

Waiting for the self-test lights to go out also avoids issues with systems being interrupted during their pre-flight tests, resulting in strange behaviour; as has been reported with the audio (locked display or non-functioning steering wheel controls), ABS/DSC (intermittent errors), Climate Control (no response to adjustments).
