3.3 won't start.

[Sh03d]

Alright, I'll tell you everything I could find,
I have no spark.
My tach does not move very much at all when cranking.
I cannot smell fuel coming out of the cylinder when cranking or on the spark plug. But I do have fuel at the rail.
My DIS module is held tight with the two bottom bolts. The top two managed to cross-thread so they are close to tight but maybe 1 cm away from the DIS module.
I used Dielectric tune up grease on the back of the DIS and spark plugs.

My only guesses are Crank sensor-Lack of tach/no spark.
Poorly grounded DIS module-No spark.
No fuel???

I'm taking any ideas here.

I'll be checking codes soon.

 

[SASHO91]

I'd suspect the CID before the CPS.

have you checked your ground(s)??

The DIS grounds itself by the bottom bolts so that shouldnt be an issue... yet... i would however try to fix that problem...

have you ran the codes yet? KOEO i mean.

 

[NotSoSlowSHO]

Do you have a multimeter? If you do, you can quickly rule out any ground issues quite easily.

Otherwise, start retracing your steps. Something (obviously ) isnt right.

I have similiar problems on a friend of mines car... any chance you may have smashed a wire or something? I need to locate the schematic for the eec to wiring loom behind the cam sprockets where the DIS and CPS wiring runs. Anyone have those or know where they can be found? I am curious as to what you find, and if I by chance get my no spark issue resolved I'll post it here. Good luck.

Codes are 242, 411, 111.

Brain fart. What does CID mean?

And To check grounds on DIS which wire do I want to look at?

CID=Camshaft Identification Sensor... on the end of the rear cam.

Ah alright. It's been a long weekend. Thanks.

I think I read the codes wrong. 89s have two digit codes right?

I used Dielectric tune up grease on the back of the DIS and spark plugs.

Out of curiosity, what type and brand of grease did you use on your DIS module? Straight dielectric grease (the type you use on the ends of spark plugs and spark plug wires) is used to insulate electrical components and will usually prevent an electrical current from being conducted between components. IMO, only a quality heatsink compound should be used to coat the back of the DIS module.

Hopefully these will help:

Yep - see below for possible handy reference.

The diagram link is no good... hope it is an effect of the crash

Whoops - right you are!

Hopefully Beth will step in and shed some light as to their whereabouts.

I used Permatex Dielectric tune-up grease. I guess the stuff used on spark plugs. Can I not use any grease for temporary use?

*Edit* I just cleaned all the grease off the back of the DIS and it didn't help.

NO you can't just use any grease, and its not dielectric grease thats supposed to go on the DIS module it's Dielectric (heat sink) compound (same stuff used to keep a CPU cool in a computer). It's purpose is to give the DIS the maximium amount of surface area contact to the intake for heat transfer to keep it cool during operation.

Now if you had this car operating vary long without the heat sink compound it is possible you cooked the DIS module. If your tach isn't working it points to the CPK (Crank Pos Sensor). The CPK produces rpm/tach info and provides it to the PCm which send the signal to the DIS (Ignition control module) and the Tach.

If someone could please read these codes. BTW I ran out of video so at the end it blinks two more times.
I'm getting 12, 42, 41, 11, 11. Which I think is wrong.

 

[naval-avi8or]

You also will only get a an inital 2 second fuel pump operation (what you hear when you initially turn the key on) to prim the system. The pump WILL NOT operate until it recieves a valid ignition signal.

Codes I read: 24 and 11

24 Intake Air Temperature (IAT) or Vane Air Temperature (VAT) sensor out of range - IAT VAT

 

[projectSHO89]

24 IAT code will be present if the ambient is below 50F. If so, ignore it. In any event, an IAT won't **** your spark. Neither will a CID sensor.

DIS Ground path: Lower two module screws to crossover tube. Via tube mounting bolts to engine. Rear head to body via heavy strap at #1 cylinder.

Common errors: Painting the crossover tube or intake (paint insulates the ground contact, not bolting the crossover to the intake, not connecting the ground stap. All can cause a "no spark" problem.

Dielectric grease is used to fill volume so water cannot infiltrate and cause corrosion. It should not be used for heat sink compound. In an electrical connector, it will not interfere with a mechanical contact as it is squeezed out of the joint allowing the needed metal-to-metal contact. I use it ione EVERY connector I service for any reason if I have it on hand. It's simply a preventative measure.

The CPS and CID sensors can be checked with a meter or LED test lamp by connecting to the correct DIS module pin and cranking the engine or turning it by hand. rangerj and I have covered the procedure in the past. A little detective work should locate it for yourself.

Make certain you have your 12V supply to the coil via IGN COIL fuse.

Links for the wiring diagrams have been fixed. The new IIS version.....long story, not going into it here as it's neither here nor there to Ed's problem.

Ed, also verify that your IRCM has power. Do all your lights work inside and out? If not you might check fuses and fusible links. What about the ground wire for the EEC? Are the contacts inside present and not bent? Does the connector fit snugly? For the connector on the back of the computer, are all the pins present and not bent?

 

[SASHO91]

This is kinda out there, but have you checked the Fuel Cutout switch in the trunk??

I got it running by swaping the Cross over tube.
Back to work, I'll update more later.

I painted my intake, so I think your right on the paint. Right now I'm going to clean off where the two mounting bolts are, the back of the intake, and the intake brace.

Thanks for help with reading the codes. I may have smashed something when removing the engine.

*update*
After grinding off the paint it maybe helped alittle but still misfires like mad and won't idle. It back fires in the exhaust and sometimes intake, and Oil smells of gas.
