'93 Loyale distributor question...


Recommended Posts

Howdy fellas.

I have a soob that has some difficulty. It started running rough about (missing occasionally) while operating. I didn't think too much of it till it completely died. I started the checklist (fuel/spark) and saw that it was getting fuel. I bought a new D-cap and rotor and pulled the #1 plug wire and found serious corrosion. (A friend had helped with a tune up about 2 years ago). The plug wire going into the D-cap had not been inserted all the way. I imagine it had been arching inside the cap for that long and finally quit. When I changed out the cap and rotor it still won't start. I checked the resistance on the coil and it is good. I get a decent spark from the coil to cap wire and from cap to plug wires.

Question: Is there anything else that may have fried?

This is an LED style Distributor.

 

Thanks in advance.

I want to know how you "saw" it getting fuel?

 

You have the "LED" distributor

(Crank Angle Sensor), and you have a fuel injected model.

(SPFI)

I don't know how you "saw" the fuel?

 

Sounds like you have spark.

Was the rotor tight on the shaft, held on by small screw

since it's a fuelie.

 

My guess is fuel filter or pump or pump relay

but you "saw the fuel?

Sorry about the "seeing" issue. I "smelled" fresh fuel and squirted in some starter fluid. Nada. After doing some digging here I am seeing some steps to take.

Fuse #5.

Grounded screw on coil bracket.

Spark accelerator on coil bracket.

 

I'll check all of these and get back with an update.

Thanks Skip for the quick response!

Okay, snow worries mate, that makes much more sense.

If you have the good spark you said you have

all these items are NA (Not Applicable)

They are all needed to make a good spark.

 

The rotor screw I mentioned can cause a no start.

 

Connect the green connectors by the driver's side hood hinge.

Turn the key to run, do not start it.

Fuel pump should cycle.

 

Use a timing light to check the ignition timing (20 deg BTDC)

Crap!! Thats the last time I let a friend check things for me!

I had a friend do the spark check list. I went back through the spark trail:

-coil to Dcap, good spark

-Dcap through plaug wire, no spark!

 

So, after reading through another post relating to an optical sensor, I may have a bad sensor?

 

The fuel pump does kick on when I did as you suggested Skip. I will look for one of these sensors in our junk yard. I live in a rural area so it may take a few days.

 

BTW; the CEL blinks steadily when I turn the key on.

 

Just found a post on reading error codes. Yeehaw!!!! Thanks PixO!

 

 

 

 

Thanks again for all your help.

John, since this is the case the optical sensor in the dist is

good, if it were not you would see no spark anywhere.

Sensor is large black box at the bottom side

Pull down the panel that is above your knees when driving.

Up next to the steer. col you will see the ECU

 

The end of the ECU will have a small hole in it

with a LED down inside. It is called the 02 monitor

That is the place to read the codes.

 

Since the CEL is flashing, turn the key to on (don't start it)

and read the code.

First, verify that you're timing belt is still intact and hasn't slipped. Easy way is to remove the drivers side end cover, and the inspection cap at the rear of the block. Line up the center of the 3 TB location marks, and the dot at the top of the Cam pulley. If that is good, see below.

This is 99% conclusive that you have a defective or incorrect Cap and/or Rotor. If the spark is going into the disty, but not coming out, has to be one of those 2 items unless you have a broken or slipped timing belt. See above.

 

Even with a slipped belt, the Cam and disty would have to have gotten out of time to cause this and that could only happen if the disty was removed, or it's drive gear sheared(highly unlikely)

 

 

BTW; the CEL blinks steadily when I turn the key on.

 

 

You're green test connectors are hooked toghether. You should hear the fuel pump running in time with the light blinking. Unplug them to take the car out of D-check or *Test* mode.

Thanks Gloyale. The timing belt is good. I can turn the fanbelt on the Alt and the rotor spins. Although it could have slipped... HMM. Hate to think of having to deal with that.

Went home during lunch and checked the ECU. 5 rapid blinks, space, 5 rapid blinks, etc...

 

I will scour the forum for this code. Looked on "Troublecodes .net" and didn't see "5" as a code, maybe "55"?

Thanks again for the help.

code 5 is the model designator. Means SPFI, MT, Non California car, IIRC

 

If it is showing you this code, then there are no active trouble codes and all is good.
