96 dodge caravan wont fire on cylinder 1 or 4. coil pack is good. fuses are good. just no spark

1996 Dodge ram 1500 NO ENGINE TOLD OF 5.GAS ENGINES
3.9 TO 8.0LITERS. AND A DIESEL NOT YOURS.
POST YOUR VIN AND WE KNOW WHAT ENGINE IS THERE. X5

SO IS AN AUTOMATIC TRANSMISSION?, YOU DID NOT SAY DRIVE IS STUCK IN 1ST GEAR.?
PRNDL
DOES REVERSE AND LO(L) WORK?
CHECK FUSES?
SCAN IT YET?
CHANGE SPARK PLUGS 1 AT A TIME?
IF YOU MESSED UP SPARK THE ENGINE WOULD SHAKE SUPER HARD AND HORRIBLE POWER AND NOT GO FAST ENOUGH TO GET TO 2ND GEAR.
IF ENGINE (NONE TOLD ) HAS COIL PACK WITH 2 OR MORE SPARK WIRES, THOSE MUST NEVER BE MIXED UP.

3.9 LITER
SPARK
The front coil pack fires six cylinders and the rearward coil pack fires four cylinders.
NEVER MIX THESE UP
5/10, 9/8, 1/6, 7/4 and 3/2.
END 3.9L EXAMPLE.


ONLY CHANGE SPARK PLUG 1 AT A TIME.
ONLY CHANGE COIL PACK HV SPARK WIRES, 1 AT A TIME
OR FAIL YOU WILL. (OR BUY NGK COIL PACKS THAT ARE MARKED CORRECTLY )

NO FIRE OUT THE COIL OR YOU HAVE A MISFIRE ON CYLINDER # 2

V-6 I ASSUME? MORE THAN LIKELY, 3 COIL PACKS CONTROL 2 CYLINDERS EACH. MAKE SURE YOU ARE GETTING A SPARK FROM THE ONE THAT CONTROLS 1 &4...OR ALL WIRING IS INTAVT
** IF THIS IS A 4 CYL. SAME THING...LESS COIL PACKS IE: ONE COIL PACK FOR 174 AND ONE FOR 2 & 3

have you checked fuel injection may have faulty injector, or vacume leak. asuming you have good compression on #1 clynder

here you go.

This is a quick explanation:

1996 Dodge Caravan
3.3 liter




The big rectangles are referencing the engine, the cylinder associated to it's "firing" are the colored circles, and the are also the location of the spark plugs....the smaller lego-looking block is your coil pack. The spark plug wires run from the coil pack to the spark plug on the engine. The wires match 1 to1 or black to black...and so on....

When these are matched to each cylinder/spark plug and it's wire leading to the matching coil pack position, this is it's "firing order". If one of the wires is "crossed" meaning, not 1 going to 1, then the engine will "miss-fire".

For the 2.4L:
Firing Order:
1-3-4-2
Cylinders:
1---2---3---4
(front of Van)
Ignition coil:
1----4
2----3
(front of the Van)

For the 3.0L
Firing Order:
1-2-3-4-5-6
Cylinders:
1----3-----5
2----4-----6
(front of Van)
Distributor:
-----2-----1------
3----------------6
-----4-----5-----
(front of Van)

For the 3.3L:
Firing Order:
1-2-3-4-5-6
Cylinder:
1----2----3
4----5----6
(front of Van)
Ignition Coil:
6---3
4---1
2---5
(front of Van)

For the 3.8L:
Firing Order:
1-2-3-4-5-6
Cylinders:
1---3---5
2---4---6
(front of Van)
Ignition Coil:
6---3
4---1
2---5
(front of Van)

FIRING ORDER PER 4 CYL.

It could very well be a bad coil pack,or you have low compression in that cylinder.If the compression is good then go with the coil pack,if not you may need a head gasket or an intake manifold gasket.

A P0306 code means that the the ECM has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #6.

A code P0306 may mean that one or more of the following has happened:
Faulty spark plug or wire, Faulty coil (pack), Faulty fuel injector, Burned exhaust Valve, Poor compression, and Defective computer. 

Check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the Caravan, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). The number six cylinder is the one towards the radiator and drivers side. If you are going to change all the plugs and wire keep me posted, be glad to help. Good luck and hope this helps, P0300 just means multi miss fire.
