Hey I posted a problem on this same thing well. I checked the relay fine changed the plugs wires cap..... and so on.. I did need a new Gas cap so I got one of those. I then thought it m ight be gas problem for a gas station Still same thing not as bad as be for. Could a starter do this it will crank and then shut off then I have to crank it again soem times and it starts right off. In the morning it starts right off. SO WHAT DO YOU ALL THINK !!!!!!!! Im so confused I dont know where to start now.... When it is running it runs great. I did not replace the relay I did a test that some one told me to use a tester and hold it on the fuse that works the fule pump when I turn the key tp start it the light should come on the tester that will let me know the relay is working... Now where to look. I have never had a problem until this week.....

 

Speed sensor locate in the back of the engine.

 

What does it do ?

 

Where at on the back of the engine is the sensor? and is it close to the drain for the AC and cou;ld water cause it not to work right? How hard to replace?

 

The Speed sensor tell the computer when to give spark and pulse the injectors.

It is located at the back top where the transmission meets the engine. Find it and inspect the sensor closely.
If the outside sheilding is coming off at all replace it.

No the A/C wouldn't even come close. The drain is under the car.

 

Thank you for the email and the info I will check it and see if this is it.. Would it do it every now and then ?

I checked the covering on the sensor and found that it was in really bad shape the black plastic is torn and just in really bad shape. I looks like the wires inside are in good shape but they probly are have a small cracks in them I was thinking if that was the case could the wire hit the block and maybe have some times shorted out the sensor some times... ?

 

Yes that is exactly what happens.

 

Hey thank you for your help and I also orderd a ECU and a new relay the other one had 1992 on it LOLOLOL< so that should do it.. DO you think that I should go ahead and change the ECU?

 

NO on the ECU till you see if the speed sensor and relay fixed it.

 

How much does this sensor cost!

 

I think like $35.00 or so.

I don't really deal with the prices.
