Sounds like you have the firing order right but your off on the #1 on the distributer. Every time you get an explosion coming from the carb its misfiring. Find the #1 on dist and continue with firing order

Bring #1 cylinder up on T.D.C.,(top dead center) firing stroke ,remove #1 plug place a finger over the hole when the air from the cylinder pushes the finger off of the hole, check timming marks make sure they are lined up, remove distributor cap see where rotor is pointing this should be #1, then just follow firing order around the cap in indicated direction

1990 geo storm sohc is running rough. Parts that are new: cap, rotor, plugs wires,plugs, pickup coil, and the ignition module looks brand new. The coil is old, but is still sending spark through all the...


I would look into replacing the coil even though it is sending spark it might not be enough and I would go through and just double check all my wires as well as the firing order because if it's off just a little it will make the car run rough

THERE IS ONLY ONE FIRING ORDER FOR THIS IT HAS BEEN THE SAME SINCE 1960??? 18436572 WITH NO1 IF YOU ARE STANDING STRAIGHT IN FRONT OF THE ENGINE YOUR HEI DIST SHOULD HAVE 2 PRONGS STRAIGHT ACCROSS FACING YOU IF IT IS NOT YOU MUST PULL THE DIST, ROTATE THE ENGINE AROUND TO COMPRESSION STROKE, VERIFY THIS BY THE POINTER ON THE TIMING COVER SET IT TO 0 WITH THE PISTON IN NO1 CYLINDER UP IF NO 1 PISTON IS NOT UP FULLY EXTENDED IN THE SPARK PLUG HOLE YOU ARE NOT AT NO 1
IF THE PISTON IS FULLY EXTENDED AND YOU HEARD A AIR SOUND THEN YOU ARE RIGHT, PLACE THE DIST BACK IN TURN THE ROTOR 1 TO 2 NOTCHES BACK TO THE RIGHT AND HAVE SOME ONE CRANK THE ENGINE IN SPURTS, IT SHOULD DROP IN, THEN REPEAT THE PROCESS TO VERIFY YOU ARE ACTUALLY ON NO1 THEN BEGIN THE WIRING

1996 Jeep Grand Cherokee 4.0 4 wd - changed wires, distributor cap and rotor - now it will not start? Did verify the firing and that all were plugged in correctly.


If the wires are in the correct order, also make sure that you used the correct starting point, otherwise the base timing can be off by as much as 60 degrees. Turn the engine till the crank damper timing mark is pointing to 0 or tdc on the timing scale. If the rotor is pointing towards the engine, turn one more time. #1 is roughly when the rotor is pointing towards the passenger headlamp. Order is in the direction the rotor turns when cranking. If the engine was running with no problems before the change, only other thing could be that you inadvertently unplugged something or the security system armed. Other possibility is that if you did the change due to a running problem, whatever was causing that finally failed.
If when you remove the cap again you find that the rotor is damaged, check the dist shaft for side play.
Are you getting spark?

Distributor cap firing order diagram


1-3-4-2
Marker on dist is number 1 (TDC) next with correct rotation of the crankshaft should be cyl 3 and so on. The corresponding firing order should have a TDC orientation meaning during power stroke the valves should be both closed. Same at the dist cap 1-3-4-2 in the correct direction of rotation.

1990 chevy 350 distributor wiring diagram and firing order


The firing order is 1-8-4-3-6-5-7-2.
The distributor rotates in a clockwise direction. The engine must be on the compression stroke on the #1 cylinder. Line up the timing marks. Remove the cap and the rotor should be pointing to approximately the 5 o'clock position.

Good Luck
