I have checked to make sure the plug wires are in the right order. I did not put the rotor 6 degrees before TDC, I put the rotor directly in line with the number one plug. I will check to see if the plug goes on the throttle body.

What else would cause it not to get any spark? Does the spark start from the ICM, go to the coil, to the distributor and then to the plugs and cylinders?

 

There are two similar plugs on the intake, both were plugged in, and the notches on the plug are different.

 

If you have the motor on exhaust stroke instead of power stroke then this could cause it. One way to ensure you are at the correct placement is to manually turn the motor over (do not turn the motor backward) to 6 degrees BTDC and remove #1 plug (that is the front drivers side). Place a long screw driver down the spark plug hole and see if the piston is in fact at the top, if it is then you are on TDC compression stroke. Then place the #1 wire to the rotor center with #1 and lock down the distributor and clasp the distributor cap.

As for the coil, it is powered by the PCM, then fires the coil, then fires the distributor, then fires distributor, then fires the cylinder. Mopar don't have a ICM that I know about, kind of a Ford thing there.....LOL

There are 2 things that control when spark should be deployed.
1. The Crankshaft sensor (rear of the motor on the passenger side).
2. The Camshaft sensor (under the distributor) like the old points system.

So after you ensure you are timed, then check these 2 inputs. Then check the coil and or coil wire. Then suspect the coil. Thing is, it looks like your TPS is unplugged, get it plugged back in!

 

Tps has a plug n in it. This one wont fit, the notches are different.

 

I say follow that advice right there

 

Take some good pictures.

 

Is that the crank sensor plug? The crank sensor is on the passenger side of the trans bell housing right behind the block, make sure that it didn't get unplugged while you were working back there. There is a lead that comes off the sensor and plugs into the harness around the distributor. No crank signal...no spark.

 

Ok, guys. The Durango is running. The crankshaft position sensor was not plugged in. It was that plug that I was wondering about earlier. Now it is running rough as hell. It idles between 750 rpm to 1200 rpm then will drop lower and lower til it shuts off. I'm thinking maybe the timing is off. Do I set the timing to TDC or a few degrees before or after? Thanks for your help everyone. Merry Christmas!

 

Just read this. Right on.

 

The ignition timing is not adjustable it is controlled by the crank sensor and the computer. Now turning the distributor will change the fuel injector timing and if it is not set right it will affect how the engine runs, Set correctly it tells the computer when to fire the correct injector at the correct time.

Now if you have #1 on the distributor cap in the correct place the easiest way the find #1 COMPRESSION is......Take the #1 plug out (front drivers side) unplug the coil, or coil wire so it does not start, Put your finger over the hole where the plug came out and have a helper bump the key so the engine turns a bit each time...when you feel air pushing out...you are coming up on the compression stroke. Now turn the engine so that the the timing mark is at 0 top dead center (TDC) . O.K pull the distributor cap ( I know, easier said than done) and see if the rotor is pointing right at #1 on the cap, if not you will have to turn the distributor so it points right at #1 on the cap. If in the case that it is off enough that you have to pull the distributor up and change the position of the gear so when it sits back in the rotor will point at #1 on the cap, remember that it will rotate as it goes in with the beveled gears so it might take a coupe stabs to get it correct.

One more thing...if it doesn't sit all the way down on the block after all this and you think "crap if it would set all the way down it would be spot on" then the oil pump drive is not seated in the dist gear....Don't try to tighten the hold down to push it in...just apply downward pressure on the distributor by hand....watch your fingers and have a helper bump the key and it should drop in....roll it back around to TDC COMPRESSION and make sure everything is good. Put it all back together (Plug in the coil, tighten the dist hold down) and it should be close enough to run decent ....You need a scan tool to set it exactly where it should be...Hope this gets it going for you...Check for vacuum leaks The PCV valve vacuum line goes to the nipple on the intake you had circled in one of your pics. The breather goes to the air cleaner. Good luck and Merry Christmas!
