Check your valve lash and compression.You can get a cheap compression tester at auto zone.Any thing under 100 psi or a difference of over 30 psi between two cylinders suggests worn parts or improper valve lash.

04 mitsubishi galant won't start..started off


Sounds like your Timing Chain or Belt Are Damaged and Caused your Ignition Timing to Jump out of Time, Also check your Distributor Cap and rotor NOTE: if you have a Distributor ,Some are Distributorless. Pull your Spark Plugs out BEFORE you Do Locate #1 Plug its in Front of your Engine.And Trace the Wire to the Distributor Cap. If you have a 4 Cylinder #1 is in the First Plug in front of vehicle, if its a V-6 #1 Plug is on Left side first plug in Front. Depending on which engine you have will determine if your wires go into the Distributor cap Clockwise or Counter Clockwise. So BEST to Simply Mark them to get them back in same order.You'll need to Get the Enging to crank over and have a Buddy Put a Compression Gauge in #1 Cylinder and Bring it up to TDC (Top Dead Center) thats when the piston is up and gets the Gauge to Move up then your on the Compression Stroke, Then check distributor rotor to see if its pointed to where your #1 Spark Plug wire came off or at least close to it.Just hit the Ignition Switch off and on Until you have it showing compression on Gauge. JUST ON and OFF that Fast. If the Rotor is pointing To a different Spark Plug Wire in the Cap, Sounds like timing Jumped. Hope this will help you solve your problem or at least find it. If you don't have or not sure on How to do this i recommend you have a Qualified Mechanic Shop run the Tests. Thanks and Good Luck

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 have a 1993 chev pick-up v6 4.3, i just installed new spark plugs,new plug wires, distributor cap and rotor button.All plug wires are back in the right position,and i used the firing order 1-6-5-4-3-2...


This diagram is for 1998-1995 Chevy 6 cylinder 4.3L engines.
Your got the firing order exactly correct, at 1-6-5-4-3-2, but here's the thing to double-check:
The distributor rotation is clockwise (note badly rendered arrow in picture).

Since you probably got everything right, then you're left with really unusual/rare causes of
failure of the ignition system:
(a) rotor button misaligned/failing to make contact?
(b) rotor button not pressed onto distributor shaft far enough therefore failing to provide correct
proximity to distributor cap contacts when coil fires
(c) coil wire or contact loose/disconnected - press coil wire firmly down into distributor cap.
(d) distributor shaft of other damage caused during installation of rotor.
(e) spark plug wires defective from factory
(f) spark plugs defective from factory
(g) battery low - may need a charge to start
(h) ICM (ignition control module) failure - hook up your HEI (high energy ignition) tester, and
watch the quality of the spark on each cylinder.
(i) fuel problem? If spark is being properly delivered, its gotta be a fuel problem...
(j) distributor cap not screwed down flush to top of distributor? maybe just on one side?

Inspect the inside of the distributor cap - if there are lots of little metal bits all over the inside
of the distributor cap, then you know you have a misalignment of some type in there, and the
rotor and cap are destroying each other. normal operation will throw a quota of spark-ed off
metal bits inside the distributor cap, but since your cap is brand new, your attempts to start
the engine should have rotated the distributor so few times, you should see no metal debris.

Inspect the distributor cap contacts to see if any spark marks are more of less in the middle
of the cap's proper "contact zone". If not, you've diagnosed an internal misalignment, which
you know how to correct.

Your misfire can be cause by couple of things but the cheapest way that you can try to fix your car is to do a tune up by replacing:
1)all spark plugs
2)do a oil change
3)spark plug wires
3)distributor cap and rotor

note misfire can be cause by:
1.bad gas
2.spark plug and/or wire
3.distributor cap and/or rotor
4.valve adjustment
5.injector
6.off timing
7.ECM
8.bad wiring(power, ground or feed line)

Change my spark plugs and distrubutor cap and the 85 ranger want start


You may have got the spark plug wires out of sequence.
Reseat the coil wire going to the center of the distributor cap Check the spark plug wires at the distributor against the firing order as follows:
The spark plug firing order is 1 - 4 - 2 - 5 - 3 - 6 The distributor rotor turns CLOCKWISE The engine cylinders / spark plugs are numbered :
firewall 3 - 6 2 - 5 1 - 4 front

I changed the spark plugs and wires on my chevy s10 2wd pick up, which is a 4 cylinder and now it will not turn over. I might have the wires mixed up on the distributer cap. Can someone show me a picture...


GET A PIECE PAPER DRAW A LARGE CIRCLE TOP UPPER HALF CIRCLE LEFT TO RIGHT WRITE NUMBERS 1 AND 3 BOTTOM HALF CIRCLE LEFT TO RIGHT RIGHT NUMBERS 2 AND 4 THAT YOUR DISTRIBUTOR SPARK PLUGS WIRES LOCATION.STANDING ON SIDE OF ENGINE WHERE DISTRIBUTOR IS LOOKING DOWN AT DISTRIBUTOR 1 AND 3 FIRST TWO SPARK PLUGS TERMINALS NEXT TO ENGINE.

Need to get my hands on a manual for a mazda b2600. Just put a new head gasket in it and the timing is all out.


take the spark plug out of the hole on the engine. the very front plug.
have someone bump the engine for you. take the cap off of the distributor, and when your friend bumps the engine watch the way the rotor is turning. i think its counterclock wise. but anyway, hold your finger over the spark plug hole and have the friend bump -bump- bump the key until the air pressure "Pssst" blows your finger out of the hole. thats the compression stroke of your engine. and right now its set to send a spark to that #1 piston.
SO look at the rotor, and pay attention to what direction the rotor is pointed. and when you put your distributor cap back on, your wire for #1 spark plug has to be pointed at the rotors tip, to get spark. so put cap back on, and then put #1 at the rotor tip, and remember what direction the rotor spins ? now put your spark plug wires on the cap to match the "firing order" The firing order is 1-3-4-2 with the cylinder closest to the front of the vehicle being #1 so if the rotor spins backwards . wherever the rotor tip is now ( since you bumped it to the compresson stroke ) on the #1 cylinder, you know where 1 is. now put #3 piston wire on the next plug, on the distributor then 4 , then 2. tighten everything, put the spark plug back in. and start your truck bro.

Ithink my spark plug wires are in the wrong order, how do Ifind t


On any four cylinder engine the firing order is always 1-3-4-2. Cylinder 1 is at the front of the engine, the same end as the timing chain and the opposite end to the gearbox.

Remove the spark plugs and manually turn over the engine until the timing marks line up (down by the crankshaft pulley). You can use a socket on the crankshaft nut to turn the engine bit by bit, the purpose of removing the spark plugs is to prevent cylinder compression making it easier.

Once the timing mark has lined up, remove the distributor cap and observe the position of the rotor arm and briefly pop the distributor cap back on: the lead exiting the cap above the rotor arm should go to cylinder #1. The next quadrant that the rotor arm advances as you turn the engine over to will be the position that the lead for cylinder #3 attaches. By the same process you can then identify where the leads to cylinders #4 and #2 go.

When finished, ensure that the distributor cap is securely fastened and refit the spark plugs: if they're taper seat spark plugs (no washers) then when they just get tight then tighten no more than a further 1/6th of a turn. If they have washers then it's an extra 1/2 to 3/4 of a turn and a bit more if they're brand new plugs where the washers have never been compressed. Refit the leads in the correct order which you've just established and make sure that they're secure and you should be good to go unless there's another problem.

Change plugs and wire and engine will not acclerate. This is a built 350 short block chevy with pro charger.


350 Chevy engine in what? 1990 Corvette? Who built it, did you?

Sounds as though you have plug wires wrong.
Firing order is 1-8-4-3-6-5-7-2

Distributor Ignition System:
Distributor rotates Clockwise. (Rotor)
Find Number 1 tower on distributor cap, go Clockwise with Firing Order.

Distributorless Ignition System:
VIEWING the engine from the Front of the car.

Spark plug wire connections along the back, starting from Left side going to Right side;
2-3-7-4

Spark plug wire connection towards the Front of the engine;
6-1-5-8

(To guess I would say you have 5 and 7 wires switched)

Left side cylinder order is 1-3-5-7, going from front to back.
Drivers side is Left side.
Right side cylinder order is 2-4-6-8, going from front to back.
