    Are you sure that have distributor? According with GMC firing orders, for 1998 GMC 1500 Suburban 5.7 liter V-8 VIN "R" you have this schematic order...




    Are you getting any gas to the carb/injecter? If you are then check for
    firing from the spark plug wire if no firing then it is the
    coil. Some people doesn't think about checking it before doing anything.

Distributor firing order for a flat cap


What engine is in the vehicle ??

Feb 23, 2014 | 1997 GMC Sierra

1 Answer

Spark plugs and wires


It sounds like the spark plug wires are not plugged into the correct place on the distrubutor. take the distributor cap off and crank the engine over. Make a note of which direction the rotor spins. (Clockwise, or Counterclockwise) then find the firing order for that engine. Sometimes the firing order is on the intake manifold. (if you tell me which engine it has, the 4 cylinder 2.0, or the 6 cylinder 2.5; I could post you the firing order). Now on the distributor cap there is one wire post that has the #1 on it, that would be where you put the spark plug wire from cylinder 1. Following the rotation of the distributor rotor, you would put the spark plug wire for the next cylinder in the firing order after the #1 wire, and so on.

I took of*** my spark plug wires working on my small block 350 pickup and I don't remember the the firing order to put the new wires back on. Is there a diagram anywhere or is it even that difficult to...


Next time number each lead before you remove it and no. the dissy cap as well

The firing order, which should be cast into the intake manifold, for the chevy small block V8 is 1-8-4-3-6-5-7-2. The firing order is the numerical sequence in which the spark plugs are fired. The insertion position of each spark plug wire around the circumference of the distributor cap can be found according to a clock face. The insertion sequence determines the firing order. The firing order is followed clockwise around the distributor cap starting from the 6:30 position with the 6:30 position being the number one cylinder spark plug wire.
On classic chevy small block engines that use ignition breaker points instead of electronic ignitions, the number one cylinder is the one immediately clockwise of the small metal sash cover on the distributor cap. The firing order starts here. There is no sash cover on the distributor cap for GM HEI electronic ignitions, and the firing order is the same, but starting at the 5:30 position.
The firing order makes sense if you know how the cylinders are numbered. The number one cylinder is the front most on the drivers side and 2 being the front most on the passenger side. From front to back, the cylinders are odd numbered on the drivers side, and even numbered on the passenger side.
See the diagram; Click to open a printable larger image in a new window. The firing order starts with the number one cylinder. We would connect the number one spark plug wire to the distributor cap terminal in the 6:30 position. distributor.pngSince the next cylinder in the firing order is 8 (passenger side rear), we connect the number 8 spark plug wire to the next distributor cap terminal (approximately 7:30 position) in the clockwise direction from number one. You need to be sure you continue the firing order in the clockwise direction around the chevy small block distributor cap from the last installed spark plug wire. Setting the rest of the firing order is just a matter of repetition. Be sure to count the spark plugs from front to back on each side of the motor to identify the correct cylinder number in the firing order.

I hooked up the spark plug wires wrong on the distrator cap it is a 1988 4.3L 6cyl how can i find a diagram to fix this problem or tell me hoe to fix it


find the firing order which is usually on the intake manifold,put the crankshaft on 0 degrees top dead center,pull off the distributor cap and mark where the rotor button is pointing,start #1 cylinder at that spot(which that spot should be pointing towards the rear of the distributor),and # 1 cylinder is front of engine on the drivers side then it goes next 1 back #3 then # 5,and the passengers side front is #2, then #4,then #6 towards the back,and the firing order goes clockwise on the distributor.if it spits and sputters or back fires,then the timing firing order is off 180 degrees,so move every wire to the exact opposite on the cap,so your #1 plug wire will be opposite from where you put it first.then double check the firing order and all plug wires then try it.the firing order is:165432,i still dont know how to send pictures.

HEI DISTRIBUTOR PROBLEMS


on the intake manifold you will see 8 numbers, this is your firing order
from the front of the car the left side numbers are 1,3,5,7 and the right side are 2,4,6,8. now ont the distributor cap there should be a number 1 at one of the plug towers. you start there with #1 plug wireand continue.
on a chevy the firing order is 18436572 and this is the order you put the wires on the cap. now the second problem i don't know right off hand which way the rotor turns on your engine. so remove the cap and crank the engine over and see which way the rotor turns, this is the order you put the wires back on the cap. hope this helps

Caprice 5.0 won't start but turns almost over


you need three things, fuel, air, and spark. the fuel and air should be ok. Let's check the timing. Oh. are you sutre the firing order is right with the wires? Ok, they are,right? Now set the timing marks on front of engine to match up at 4 degrees after you bring #1 piston to top dead center.on compression stroke.you can tell when its on compression stroke by removing spark plug and bumping the starter untill the piece of tissue you put in the plug hole blows out.then once the timing marks are lined up,check what wire the rotor is pointing at. If its close to #1, turn distributor slowly either way untill you hear a spark jump or pop. Lay #1 plug wireon the engine with the spark plug stuck in it. When the spark pops, the plug will fire at the timing mark setting. put plug back in, minus the tissue, put the wire back on and sng doe your distributor. the firing order is casted on the intakke manifold. Like 18436572. Going around top of dis cap start at the wire you know is #1.and in the direction the distributor turns make sure wires are in that order on your manifold.don't forget to secure the distributor cap..I this distributor has points the dwell/gap will have to be set while running with an allen wrench and dwell meter.at32 degrees. No points,no ptoblem. no setting. button it all up and look around for loose anythings, especially tools on top of radiator and light it it up. Final timing should be set with a timimg light. Any problems , I'll be on the puter bot noon o clock my time. Good Luck.

Put distributor cap on blazer fire came out of engine


If when you changed the distributor cap you misplaced the wires in the incorrect order you could have caused a misfire. When looking at the cap the correct firing order for a 4.3 liter is 165432 going clockwise. Also if you loosened the distributor hold down bolt and turned the distributor even slightly you could cause a misfire.

Pasenger side isnt firing with new plugs and wires


Recheck the rotor position and spark plug wiring for correct positions for starters. camshaft sensor?
-------------------
You need to bump the starter over till you get the timing mark up on the front of the harmonic balancer to line up with the - O degree, Top Dead Center mark (TDC) first. With the Distributor cap off the distributor so you can see the Rotor. The rotor will rotate almost to the front pointing at the back of the throttle body of the EFI. You need to mark the distributor cap , once you get it on ZERO, to mark it as number one, on the post bulge on the cap that the rotor points to. this is the post we start with in putting the wires back on in sequence. This puts the wires back on the cap according to the firing order you see on the intake manifold. The rotation of the rotor you see...as you bump the started over, tells you how the wires...in sequence go around the cap...the firing order from number 1 goes in that direction. Remember on the vehicle ..the odd numbered cylinders are on the drivers side...Number one at the front ..then 3, 5, 7 to the back. All the even cylinders are passanger side 2 at the front ..then 4, 6, 8 in order to the back. You really need to tab the wires at the Cap End... as to which one is which cylinder. Use a piece of masking tape make a flag tab folded around the wire so you can easily see its number. Then run your sequence of firing order puting the wires to the cap in that order. This assumes you still have the wires on the right sparkplug....if you pulled the wires off the Cap and the sparkplugs...its OK..just mark which ones fit to the cylinder...one at a time...and tab it the same number on each end first. Post back if you are lost...tell me what has been removed...and what you left hooked up the same as it was BEFORE you started. It will go back together...and run . If you pulled out the distributor base then we need to talk.
please do rate the solution.
