anybody know how to test an EEC (Napa calls it ECU) with a volt meter?

Thanks

 

What are you attempting to test it for?

 

It is a replacement I bought from Napa.

it was working, for two weeks. then my truck died on the road on Monday. I thought it was the ICM, I replaced the ICM, truck started drove for 100 feet then died again. the ICM blow up again. have spark, fuel presser.

 

If you have spark the ICM is working. The ICM makes the Ignition Coil Fire.

 

This is the truth. Check. If. Your. Injectors. Are. Pulsating. If. So. Then. they. are. receiving. a. signal. from. the. e. e. c. indicating. that. it. is. in. proper. working. order.

 

You cannot test your EEC/ECU/PCM with a voltmeter, it's a digital device that requires more sophisticated test equipment than a simple DVM.

 

Yes I have spark.

just wanted to see if could test the EEC (ECU).

I guess not. it is so hard to get parts to my Island. sometimes living in paradise has its challenges

 

Thank you.

that's what I thought I was thinking that I could omhz test pin #60 with another pin #

 

Well you can definitely test to see if it's getting power. That's about it though.

 

You can test pin #60 by shorting Pin #2 to pin #6 of the self-test plug and turning on the key.
If the fuel pumps run then pin #60 has a good ground at the NEG post of the battery or at the body ground depending on the year of the truck.

 

thanks I will give it a try
