I think my ECU may be bad, HELP!

[John West]

Car is coming up with these codes:
03 Fuel pump relay, 15 Fault lamp, 17 Injector valves (Cyl 2,4,6), 28 O2 sensor circuit, 10 O2 sensor control, 05 Tank venting system, 16 Injector valves (Cyl 1,3,5).
Had been spratically been coming up with an O2 sensor code and a EKT circuit for years but now I appear to be haveing a major failure. Any ideas? The only thing I can think that could effect that many things at once is the ECU. Any help would be greatly appreciated.

That many codes, Yeah. Replace the ECU.
Especially if it's putting those numbers out. There are no 2 digit codes. And there are no codes that are a 120X. The lowest one is 1211

In fact. I'm really curious as to how you got to those as the numbers, and associated them with faults..

I am using my old Snap-On brick to get the codes but also have a new Launch scanner that gives me the same numbers. Found a used ECU for $125. Gonna try that and see if my problems go away. Thanks for the help.

How about the good 'ol stomp test? No bricks about it.
