How to Connect sparplug wires in the correct fireing order?


The firing order is 1342 Number 1 should be marked on the distributor cap . start from there , notice the direction the rotor turns, next terminal on the caps goes to number 3 cylinder and so on. to find number one if the cap is not marked do the following. remove number 1 spark plug and turn engine over till compression is felt, line up the timing marks on the crank pulley and timing cover. remove the dist. cap the rotor is now pointing to number 1 position on the cap.

Wiring


if you mean the plug wires do the following. remove number one spark plug,turn engine over till you feel compression coming out of cylinder, find tdc mark on timing cover, turn motor over till mark on crankshaft pully lines up with timing cover mark, remove distributor cap, rotor now points to number one plug wire, check rotor rotation, firing order 4 cylinder motor 1324 6 cyl 153624.

Timing is off on my 1990 ford f150 v8 302


There are a few ways and if I remember correctly, if you have a Module on the distributor you also have a wire sprout which must be disconnected to get base timing.

That being said, those modules still had a timing mark on the crankshaft damper and a timing mark pointer. You want to have the crankshaft visibly marked and the pointer at the DEGREES recommended for the motor. You will see TDC on most dampers and then advance it maybe 6 degrees as marked.

Assuming you are close to begin with, AFTER lining up the parts as recommended, mark the distributor #1 plug position on the cap to distributor housing so that the #1 plug terminal is known when the cap is temporarily removed, wires intact.

Then see where the rotor is pointed and remove the distributor and clock the rotor to align with the mark you put on the distributor housing. If you have a gear drive, the gear will need to be moved slightly for the rotor to twist into place when the distributor is seated. With a timing light, check where the spark is occurring for #1.

You may be close enough for the engine to start.

Other ways involve removing a plug(#1) and turning the engine until compression pushes your finger away from the cylinder hole. Line the timing marks up per specs, do the same process for the distributor rotor and try it again.

If this still does not produce the results you want, make sure the plug wires were not switched. Finally removing the valve cover to observe when intake and exhaust are both closed will help, but it is a lot off unnecessary work to be avoided.

Cant set timing and is minus 45 degrees


Are you sure you are on number 1 spark plug wire? if so your wires must be off on the cap. put the engine on top dead center on the compression stroke, that is with number 1 spark plug removed turn the motor over until you feel air rushing out of that plug hole and the timing marks line up at TDC. Then make sure that the rotor on the distributor is pointing at the number 1 plug wire, if not you will need to re-time the wires on the cap to where you make number 1 were the rotor is pointing and work clockwise around from there 1,8,4,3,6,5,7,2.

I am having a hard time getting my 02 pt cruiser on its compression stroke when i line up all my timing marks what am i doing wrong?


NUMBER 1 PISTON TOP DEAD CENTER WITH DISTRIBUTOR ROTOR POINTING TO NUMBER 1 SPARK PLUG AND BOTH VALVES CLOSED.LOOKING AT TIMING SCALE CRANKSHAFT DAMPER TIMING MARK AT O.ON TIMING SCALE.REMOVE SPARK PLUG NUMBER 1 PLACE FINGER NEAR SPARK PLUG HOLE.WHEN YOU FEEL GUSH OF AIR ENGINE ENTERING COMPRESSION STROKE.SOME MECHANICS USES A SPECIAL WHISTLE WHEN PISTON GET TO COMPRESSION STROKE THE WHISTLE WILL BLOW TO LET YOU KNOW GOING TO COMPRESSION STROKE.

Replacing distributor and I lost the position of the rotor and truck wont start... do I need to take #1 cyl to top? and the aline rotor?


Yes, when cyclinder one is at top, the rotor should be pointing towards the #1 spark plug wire

Disturbed timing...need info on resetting non-adjustable timing.


Sounds like your off just one tooth, try pulling up dist. and back it up one tooth( counter clockwise) and try it again. When you reinstall the dist. it always goes in just before #1 not right on #1. Your in the ball park.

Rigoe the points for the timing belt are usually located on the sprokets in conection with marks or dots on the engine block some where around the sprockets that hold the timing belt. Remenber to bring the piston number one to TDC (top dead center), this means you have to locate the piston number one, take the spark plug out and turn the cranshaft (the one with the pulley) by hand until the piston is all the way up. On the distributor the rotor should point to the spark-plug wire number one (you can make a mark outside of the distributor cap where the number one spark-plug wire is pointing so when you take the cap off you can see if the rotor is pointing the same direction). With the timing belt cover off you are going to be able to aling all this points at the exact locacation all together. So we have: Piston number one at TDC, The rotor(enside the distributor cap) pointing to the number one spark-plug wire, and the mark of the sprockets pointing the marks of the engine block( litle dot or dash). If you get all this right you are have done a good job and ready to make a trip you can get all this just by turning the cranshaft by hand with a rachet and a big socket. God bless you.

1987 GMC Jimmy Distributor cap and Rotor replacement


A diagram may not be needed as its a reasonably easy fix to do on your own.the distributor ca p will only fit on properly one way because at the base of the cap locaters can only fit the distributor if they line up.When doing the spark plug leads do them one at a time and if nessecary write or mark leads as 1,2 etc .The rotor can only fit on one way but put a mark on the distributor to show where the rotor was pointing when you took it off and if it still points there when the new one is fitted.When changing distributor cap and leads they have to go to the correct place.Pays to mark the outside of distributor cap where the locating bits are On the new and old one.Fit the new cap and rotor then take a spark plug lead and fit to new cap 1 at a time.You can tell by lining up the marks on the outside of the distributor cap when you hold them one on top of the other.Good luck
