Yeah, I checked that out, my copy is pretty blurry too. I believe that it comes from the start relay, although it is pretty hard to trace from the conduit coming from the computer starting right under the cooling liquid resovior to the starter relay. After cleaning some contacts under the dash yesterday, B7, and D5 under the hood, are measuring 12 V. I can't put my fingure on why, all of the wires look like they are in fairly good condition (and I did get to see them all, unfortunatly). It is possible that I may have measured incorrectly previously, but seems rather unprobable. So the situation is now that we have spark to the spark plugs, we have perfect fuel pressure, but we have no signal to the (practically new) injectors. A Chiltons told me to measure the resistance across the injector harness leads. Should be about 5 ohms on every injector. It is 6 ohms, which I wouldn't think would be too big of a deal, but the Chiltons told me that if it was not exactly 5 ohms, then there was a problem. If it was more, then test with a DRB II tool (I am getting sick of hearing about that thing
), and that the ECU is probably bad.
So I am looking for a new ECU today. I am concerned however about why this one has burned out, if that is the case. Is there a place online that sells them? I am not sure where to begin with trying to find out why this one is burned out. I may have a dealership do it if they cover replacement should the new one burn out, although I am sure that is quite expensive.
Is there a place online one could recommend for ECU's?
