No, the primaries fire sequentially alternating between front and rear rotors - at least when the secondary fuel injectors are not firing under 3,800RPM.

I am talking about when you are just cranking the motor over.. should they both fire.. how do you check and see if your injectors are working

i'd pull the spark plugs and see if gas shoots out when you crank.

You can do that .. but Be carefull I blew a 3 foot ball of flame and had to dash for the extingiusher when I tried that ... it burned itself out in a matter on seconds.. but it took a bunch of my chest hair with it.

Yes, both primary fuel injectors fire alternately.

Pull the fuel injectors with the fuel rail.&nbsp Secure the fuel injectors onto the fuel rail so it doesn't leak or pop out - I use wire or wire ties.&nbsp Have someone crank the engine over - you'll see the fuel squirting...
