Noid light and spark plug testing

[87MJTIM]

Not MJ, but Jeep 4.0 HO related.  I have installed a 93 4.0 into my 84 CJ.  I have turned the key, it cranks but does not fire.  

 

It has fuel and spark.  I used a noid light and spark plug test light on #1 cylinder.  The light sequence is spark plug then noid light.  I have to assume I'm 180* off.

 

How do I adjust this?

did the engine run prior to removing it from the donor?  have you pulled the distributor at all?  and have you double and triple checked the plug wire order on the cap?

How did you determine which light lit first?

Yeah, I was going to ask the same....................

 

 

Everyone needs to learn to index a dist. I want to see where the rotor is at TDC.

I never heard the engine run.  I got it from a client that has an auto shop.  He had a customer leave it.  My client said it had a blown head gasket.

 

I had the head rebuilt: magna flux, resurfaced, etc.

 

On the block, I changed the timing chain and sprockets, new seals and gaskets all around.  I was careful when I changed the timing chain.  The old did not come off until the new was set and ready to install.

 

I did not pull the distributor until I primed the engine for oil.  I marked the dizzy so I would put it back in the proper location.

 

I turned the engine over to make sure I was at TDC.  (I think I did this before priming the engine.)

I pulled the fuel pump relay.  Plugged a noid light on the first injector wire.  Plugged the spark plug tester to the first plug.

 

Cranked the engine.  

 

The light would come on to the plug first, then the noid would light up.  There is a delay between the two.

My wires are set 1-5-3-6-2-4

May not matter which came first, the light or the noid. What matters is that you get one and then the other, over and over again.

Two attempts with several rotations of the engine gave the same result: spark plug - short delay - noid - long delay - spark plug - short delay - noid.  Repeat this cycle.

 

Just my though, the noid should light first injecting fuel into the cylinder. Then the plug should light, sparking the fuel/air.

If you have spark and fuel and no start...........180 off.

[Ωhm]

Yes, but eventually you will get a noid delay spark plug during cranking.
