Just looking for an explanation as to what is not working that is making the opti not send the signal?

Could the timing chain broke? fell off? lol

The first thing I am going to try is turning the crank and see if the cam spins??
Then if not guess I am taking off the timing cover. Go from there...

Car has no spark or fuel, due to the opti not getting a signal, I verified that the opti is working by taking it off and spinning it by hand and seeing the noid light, light up. So if it got the signal, it will send it, so what is broke to make this happen?

Thank you very much if you can answer this, as my car has been down since September

 

you may have a bad ICM

 

I had to replace my ignition coil recently, b/c I wasn't getting any spark to any cylinders. Start from the battery and troubleshoot to the coil to see if you're even getting anything into the opti to start with.

 

No mileage on Opti, ICM, Coil, basically I have already replaced the entire ignition besides the wires.
I am not able to scan it for codes.
I have also went through it with a DMM and everything seemed to check out fine.

 

Also just checked Shbox site and verifired this: quoted from his site:
The opti has two functions in the spark process. The first thing that happens is as the cam turns, the optical section of the optispark picks up the signals by the rotation of the shutter wheel. The pulses are sent to the PCM via the optispark electrical harness. The PCM processes the signals along with other sensor input and determines the proper time for the coil to fire. The PCM sends a signal to the Ignition Control Module (ICM) and it, in turn, causes the coil to fire. The spark from the coil travels through the coil wire back to the secondary ignition section of the optispark (cap and rotor), to be distributed to the proper cylinder.

From that I am understanding, that the Opti is not getting the signal from the get go. Am I right on this?

 

You got it backwards. The opti sends the [optical] signal. It gets spark back from the coil. Did you do the test on my website at the connector to the ICM?

 

The car is in FL, and I am flying down in a month to get it going.....
I did do all the test, IIRC, they all pointed to the opti, as they all were good.

I will call the guy where the car is at and have him do the ICM test.

Also, the backwards deal... what I am having problems understanding I guess, I think I have it right.... is, I know the opti sends the signal, and from what I have proved is the opti is never getting a signal to SPIN the optical sensor to the PCM. So I think that somewhere before the OPTI comes into play there is something wrong! Timing chain broke is what I am thinking, or am I just way off with that?

 

If I spin the OPTI by hand the car will try and start, so everything else after it should be fine, right?
I guess I can only spin it once by hand, so it only has like one full revolution, so it stops right after.

 

If that is so, sounds like there may be some other issue. If it tries to start, then it sounds like it is getting spark and fuel. Whether they are timed correctly may be another thing. The opti has to be indexed correctly for it to send the spark at the right time to the correct cylinder.

 

I verified that by putting gum in the cam dowel hole in the opti and put the opti on and the cam dowel pin definetly inserted. I dont think the cam is spinning.
Anyway, guess what I am trying to get at is, besides the timing chain, or possibly not indexed correctly, what else could cause this problem?
Seems mechanical to me.
Well just thought of this, if I spin it and the car tries to start, then the timing chain has to be on. So there goes my hope on that. I'll take all suggestions, but at this point Im stumped, lol.

Thanks for the replies thus far

 

Is this to advanced or something? What could it be? HELP

 

Well I am in Fl right now and have worked on the car all day. Bad thing to start off with was a dead battery. Anyway got that fixed and did the ICM test. Where I was supposed to get 1-4 volts was fluctuating in the 3's. So, good to go there.
I have the new opti on the car all connected with a noid light on the injector harness, and while cranking cannot get anything. unplugged the harness on the passenger side and checked for the 5 volt ref and had nada.
Then I took the old opti and just plugged the harness into it and with the KOEO, I unplugged the harness on the passenger sidea dn the car clicked and the noid light lit up. Plugged the harness back onto the new opti that is on the car and could not get it to click or light up while finicking with the connector harness on the passenger side VC area.
Only when I hooked the old opti up to the harness ( remember that the old opti is just sitting on the rad support ) and played with the connector harness at the passenger VC would wee see something happen. Everytime I plug and unplug the harness it clicks , pump primes, and the noid light lites up.
Can someone give me an explanation for that?

Next if there is something wrong in the passenger side VC opti connector harness, can I somehow bypass it? or can you recommend how to go about this?

I fly out of here Sat morning, so all help tonight and tomorrow is appreciated, Thanks in advance
