I hooked up the other ecu and with it plugged in the CEL dose not illuminate at all. Any ideas?

Also my direct wiring helped nothing still no read with my old ECU, So it must be the ecu...

 

You know I think at this point I would just install the new ECU and take it to someone with testbook (not autologic) and have everything reset and go from there. But hopefully OKdiscoguy can get this worked out for you. He seems like a pretty sharp guy.

 

Yes the new ecu has to be programmer to the vehicle and no check engine light is normal

 

Nobody in my area has a test book. So I am unsure of what to do. Can i get the alarm module from the car I got the ecu from... I hate to spend more money, But I am out of ideas.

I unplugged a after cat O2 sensor and I unpluged my maf, Neither triped the CEL. So I think somethign is seriously up with my ecu. Dose this make sense?

 

Funny I have similar issues.

I'd have to run with my iacv or maf unplugged for a while before it gets a cel.

Try fuel temp sensor?

 

If i got the alarm module would the ecu work without programing.

 

Good question.

It may!? Let me know if you try it I might copy you.

 

Man, I do not want to spend more money for a possible fix...

 

If no one has testbook you may have to cough up the money for the stealership to reprogram the new ECU and get everything running. I think that would fix this all but that is just an educated guess and you may come out on the losing end. I understand tight money situations. Sorry about your rock and a hard place situation. I personally don't see any other options at this point but I am not an expert. Good luck.

 

Man I hate to say it but it is sounding like that old Rock Ballard " Another One Bites The Dust". Would it be possible to yank all that stuff out and come up with a simplified system like the older vehicles had prior to all the sensors and controllers?

The LR propritary test book, is that software or does it require a special computer as well?

Shame you can't replace the ECU with a modern controller like the BullyDog you hear so much about for the new diesel pickup trucks. PowerBlock and those other shows rave about those things.
