94 CAMSHAFT SENSOR/SERPENTINE BELT ISSUE

1994 Ford Escort

HI,

I have a 94' Ford Escort. The car was idling at a stop light when the tension pully kit exploded and the serpentine belt was shredded around the camshaft. At this point completely shut off. I pushed the car back to my garage and removed the shredded belts and replaced the tension pully with a brand new one. For some reason the car will not start. It's getting spark and gas and it wants to turn over but it simply won't. I've tried resetting the inertia, checking the belt for improper positioning, and looked at the Camshaft sensor. I don't understand why it won't turn over. The fuel failure and brake light dummies are both shining when I try to start. Is it something with the Camshaft sensor or timing belt?

Thanks

Not all sure how to answer this one. You have went down so many different avenues.
1. The inertia switch doesn't do anthing unless you get hit and it shuts the fuel pump down.
2. The camshaft should have a cover over it so you can't even see it.
3. Not even sure what motor you have.
And you say the belt got shredded up into the camshaft. Not possible unless the belt tore the cover off.
4. Now on all modles there is a crankshaft pully and sometimes there is a sensor on thoes and it is possible for the belt to get to it and do damage. But you wouldn't in most cases have spark. But with thar belt flying around in there it may have broke some wires somewhere down in there that would be most likely cause I can think of.
5. If you getting fuel to the injector rail ave you checked to make sure the injectors are paulsing fuel this has to be dome with a noid.
6. These are fired by cam sensor trigger did the sensor get damaged when the belt come off?
7. Answer most or all these questions and I may be able to help you further.(NOS) 8)

Alright, I've answered your questions and left the number of the question in tact. It was the Crankshaft, not the camshaft. I kept saying camshaft and mean't the other.

Here you go: 3. The motor is a 1.9 and the belt was shredded by the Crankshaft, not the camshaft
4.I am getting spark but I my guess is that the shredded belt damaged the crankshaft sensor.
5. If you getting fuel to the injector rail ave you checked to make sure the injectors are paulsing fuel this has to be dome with a noid. I have not checked with a noid.
6. These are fired by cam sensor trigger did the sensor get damaged when the belt come off? I think this is very possible. It's the only thing I can come up with. What do I do if this is the case? Replace the sensor? How?

You can try to use a test light to see if the injectors are working if you have on one side of the wire is ground and one side is power. Turn the key on hook the test light clip to the neg side of battery probe the injector wire to see wich on has power once you have found that on you will know that all the rest have power to the rest of the injectors. Now put the test ligt clip on the pos of battery and probe the other wire on the same injector while you probe the wire have someone crank the engine if the light strobes the the sensor is not bad you must do this test first.
2. The sensor is usualy mounted buy the bottom pully by a 10mm headed bolt with two wires comeing from it now if you find the wires ripped out of the sensor then replace the sensor and any thing else that is damaged there (NOS)

I checked a book and it said the crank sensor is located on the bottom left corner of the engine passanger side. Look and make sure the belt didn't yank the wires off it or damage the sensor.(NOS) 8)

Well, I replaced the Crankshaft Position Sensor and attempted to start it. Nothing happened. It kept turning over but not starting. I don't know what else could be the problem. It seems logical that if the car was running, the belt shredded, and the car died. That it would be related to the shredded belt and not something else.

Any opinions?

Logical there is nothing logical about these car's anymore, what should work and don't is not the answer. OK try this pull the plugs out and see if there real wet if so dry them or put in a new set they maybe so fould with gas they can't fire. (NOS) 8) sorry didn't mean for you to repace the sensor unless you thought it looked bad this may take a little time but we'll get it figured out it is really hard to do it this way cause I can't see the car. : Wink:

Gotchya. I'll check out the plugs and see what I find.

Thanks a bunch.
