Question about 1999 Jeep Cherokee

1 Answer

My check engine light has been on and the diagnostic machine says it's not firing on the 1st cylinder. I replaced the plugs, wires, cap and rotor and it's still not going off. The next step I'm told is the fuel injector and I'm wondering if there's an online resource for me to do this myself?

You can take a ohm meter and test resistances on injectors specs are 10.8-13.2 ohms also check plugs condition for black or white salt/ash or yellowish that help to tell what the cylinder is doing. if it is black you have weak spark and dumping fuel if it is white salt/ash your getting coolant in. if it is yellow ish your running lean no fuel ,but standard white like you put the plugs in is no spark

You need to take off the ignition wire to allow air to dry the ends of the wire. If that doesn't try replacing the wire. If that doesn't work, you may have to replace the spark plug because it may have cracked during restart. The only other thing left to do is replace the rotor button and distributer cap. If water gets into the cap, it will crack and won't let the car start.

I have 2002 Durango with 360CID engine. #8 cylinder does not fire.


Had a similar problem years ago. Since everything is electronic very hard to do self diagnostic. Make sure the boot is completely into the "Rotor" cap. Are these original wires? Not sure if some still use graphite or all copper these days. Worst case is carbon build up on # 8 piston. compression test is 1st thing. Was plug anode clean or pitted? May not be a whole bunch of help but ck these things out 1st. Best advise is think simple before you freak out.

Cap and rotor


my guess, is you did NOT replace the wires 1by1.
and messed up the firing order. (engine size not posted)
or
you bought one of this china,no-name POS rotors that fit 3 ways?
or the cap is on backwards
or the wire terms(HV) not seated.

ill assume the dizzy was never unbolted.

never power wash an engine, you force water to places that never must be...
let it dry for a day or 2.

what does FIRE to plugs mean.
i used a grounded tests spark plug , at the end of each spark plug
and there is no spark.

i ask that, because some posters say that , but only mean
the cylinders are dead, and call it no fire.
takes spark, compression and injection and timing to fire.
4 things.

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.

Well the check engine light is on and is coming up a misfire on one of the cylinders what needs to be fixed


I would suggest replacing the spark plugs and plug wires. Especially on the cylinder that is misfiring. But if you don't replace all of the plugs and wires. The problem will probably move. Also a new cap and rotor is a good idea. But a misfire means that the spark plug did not fire.

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. AND 2 AND 4 SPARK PLUGS TERMINAL ON CAP FACING YOU. THIS IS CYLINDERS LOCATIONS STANDING IN FRONT OF ENGINE.RUN WIRES FROM DISTRIBUTOR CAP TO PLUGS TO THE ENGINE SPARK PLUGS.

What order do plug wires go on distributor cap


Firing order is 1-8-4-3-6-5-7-2. Move #1 cylinder to where piston is up, and on the compression stroke (TDC). Easiest way to do this is with a compression tester on the #1 cylinder - rotor cap OFF. When you see the pressure build...you're on the compression stroke.
The rotor cap should be at the #1 cylinder firing position...simply re-install the rotor cap at this time - noting which button is #1.
Starting at #1 install the wire for the #1 cylinder onto the rotor cap...the next button (clockwise) on the cap should correlate to #8; the third button on the rotor cap is, cylinder #4..and so on.
work your way around the rotor cap until you have all 8 cylinder wires in place...ignition coil wire in the middle button.

Engine should start and run.

Hope this helps.

What do these trouble codes mean po306 cyclinder misfire detected .how do i fix the problem?


it means you have a misfire on the number 6 cylinder

this could be caused by a whole lot of reasons.

start by inspecting for a bad plug wire if it has them

check for fire on the cylinder with a spark test tool from local part store

if it is a coil-on-plug set-up, check the coil for fire

replace coil/plug wire as needed, replace boot on coil if coil needed, replace spark plugs

I have a 97 chevy tahoe. I changed the spark plugs, wires, distrubutor cap, rotor. About 300 miles later engine light came on. I thought maybe cheap distrubutor cap and rotor was cheap. I went to auto zone...


the number 6 cylinder is located (if you are looking at it from the front of the car) it is on the left side third cylinder back from the front. you probally have a bad injector that is just dripping fuel into that cylinder.
