Beetle 2.0 1998/2004 engine code AQY firing order 1.3.4.2.
replaced ignition coil pack, PCM and spark plugs. No signal comes from the computer to fire plugs 2 and 3, but 1 and 4 are firing nicely. The van WILL NOT start, but -- at times -- it tries. Please help. There is possibility that I bought a faulty PCM with the same problem that I had from the original, but I dunno.

By means of the spark plugs firing which ignites the fuel air mixture. This explosion drives the pistons downward and turns the crankshaft. The crankshaft turns the transmission which drives the wheels.
lp gas requires an ignition source of over 900 degrees F to ignite
Its a scary term at first but its easy to understand once you get the knack for it. An engine that has a 270 degree firing order means the bangs (power stroke) from each cylinder are 270 degrees of crankshaft rotation appart. When cylinder one fires, cylinder two will fire 270 degrees later, this trend would continue if the engine had more cylinders i.e. 4,6,8,10, and 12 cylinder engines. If and engine had a 360 degree firing interval its the same as above, cylinder one goes bang, cylinder two goes bang 360 crankshaft degrees later. Hope this helps. Its a scary term but its easy once you get the knack of it. Firing interval means the degrees in crankshaft rotation the power strokes are appart in an engine. Take for example the engine in the 2008 Triumph Scrambler it is a twin cylinder engine with a firing interval of 270 degrees. In this engine when cylinder one goes on its power stroke, cylinder two will have its power stroke 270 crankshaft degrees later. Ok now lets take the Cheverolet Corvette, Chevy has the firing interval at 90 degrees. So that means cylinder one fires then cylinder 8,4,3,6,5,7,2 follow all 90 degrees appart from each other. Hope this helps
On most 90s Mazdas the firing is controlled by the crankshaft position sensor that sends a signal to the ignition coil telling it when to spark, on v6 models the sensor is located underneath and to the right of the crankshaft pulley on the passenger side of the car.
BTDC stands for "Before Top Dead Center," which refers to the position of a piston in a combustion engine relative to the top of its stroke, usually measured in degrees of crankshaft rotation. This term is commonly used when discussing ignition timing in engines.
1,2. But seriously, I think what you need to know is the number of degrees BTDC that the ignition fires. This I don't know.
it keeps the firing sequence
There are several possible firing orders of a six cylinder engine, in practice however, mostly it is 1-5-3-6-2-4. The ignition interval is also at 120 degrees.
You cannot change/reset the firing order. The firing order is determined by the crankshaft, and cannot be changed at all.
Yes, a bad ignition condenser will keep a motorcycle from firing. A bad ignition condenser might also have caused the points to stick together and burn up.
