Hello everyone you have true noob here who really needs your help. Well i was driveing my 95 FWB on the highway yesterday doing about a good 70mph and i went to pass a slower car and a ofa suddenmy car just died on me.So i pulled over and restarted the car and it putted and shook like its was ether hot or it was no geting gas. So after a two hour wait i tried to start it again and it dd the same thing okay so now im mad so i try it again it fires right up and i proceded home.So thi morning i tried to crank it and........ Nothing... So i did the normal things like check the fuel rail pressur valve to see if its geting gas and got sprayed in the face. So i tried to arc a plug wire by sticking a screwdriver in th plug boot and no spark.Now i know everyone is going to say opti but i want t trubble shoot every thing first. Any suggestions?

you stuck a screw driver in the plug booot? :O never heard of testing for spark that way before, sounds like you could damage the boot that way if you're not careful.

Anyways...if you're not getting spark it could be the coil or the wire to the coil (for quick/easy checks)

That's a pretty standard way to check for spark. It sounds like your ignition module to me. I had the same problem years ago in a different car. It's an easy and relatively inexpensive fix.

Yeah, I doubt it's the opti. They typically don't fail suddenly. The opti distributes spark, it doesn't create it. It could be the coil, which is easy to get at. I'm not sure how you test a coil, but someone else might know.

You have fuel, but you might have low pressure. Get a gauge on it. If good, clean grounds on coil, then change coil wire, then ignition module. In that order.

okay im going to do try that^^^^ how would i test the ICM

Advance Autoparts can test your ICM if you remove it.
Have you checked the trouble codes?

Yes i do have it off and these are the codes i pulled from the climate control.

-00...74
-03...61, 62
-04...73, 64, 27

any ideas?

00-74 ........... Traction control system active signal with vehicle in park or neutral
03-61 .................................................. . SIR indicator circuit failure
03-62 ......................................... Redundant SIR indicator circuit failure
04-73 .................................................. ....... Spark retard monitoring
04-27 ............................... Wheel speed sensor circuit continuity malfunction
04-64 ............................................ Throttle position signal malfunction

Looks like 04-37 is the most relevant to starting issue. Clearly an electrical problem. Could be bad wiring or even bad EBTCM.
TPS is cheap and easy to replace. You might want to try that, or test the TPS with an ohmmeter for continuity of resistance change while you move the lever up and down.

If I had to guess, I'd say that the 00-74 and 04-27 are related to a bad wheel speed sensor. I wouldn't worry about it for now.

The 04-73 could be the ignition module, and related to the starting issue, but has nothing to do with the EBTCM (Electronic Brake and Traction Control Module).

It would be really unusual to have a PCM (powertrain control module) failure. The problem almost has to related to a controlled or monitored module like the ignition module or ignition coil.

I've seen some really wacky wiring issues in the past, so I'd have both the ignition module and coil checked before I replaced either of them.

okay guys i have something new for you. i pulled the coil wire and grounded it to the block and wow....... its getting spark and lots of it to. but no spark going to plugs still any suggestions

That's odd. Almost has to be the opti then. Maybe the rotor cap failed?

Well you guys i tried to avoid the obvious. But in the end it was the opti!!

After seeing all of the comments left i decided to take a lookse at my opti and my worst fears where confermed. when i took it off of the mighty lt1 i heard a rattle inside the opti spark.

turns out the two screw to the rotor wher not even in the rotor they where just laying around the bottom of the opti.

And the little pin that was on the bottom of the rotor that make shure u put it back in the right place was also broken.

And the cap.... i dont even want to talk about it........

looks like im going to need seals to.

my opti is coverd in oil inside and out

Well i guess i got what i was looking for. But it will be fixed and i will have updates on it

Here is the optispark in all of its (clean) glory!!!well as clean as some good brake cleaner would get it.I stayed up all night trying to get all of the oil and grime out of my opti!!

http://i.imgur.com/vXceY.jpg
First u have to re install the optical sensor and timing discs( well thats what i call them but im shure thats not there name.

It can only go to gether one way so you can not mess it up!

and here is how it looks now waiting on its new cap and rotor.

Okay i have a question should i buy new seals or should i just buy a new timming cover?

If memory serves, the new cover has a gasket/seal on it to seal it to the base, but it doesn't come with the oil seal, though. When I did mine I couldn't get the nice people at NAPA to find it for me. Maybe someone has a P/N for it? You definitely need one. thefleetwoodguy just posted a thread on his, and he had a new seal.
