JB3 pinout engine malfunction

sb335is · 05-23-2011, 06:17 PM

Hey,
I just received a JB3 pinout and installed. About a minute into driving I got the engine malfunction light with the half filled on the dash and said reduced power. Drove the car around the neighborhood and it appears to be driving just fine. What do I do to fix? What is wrong? The fuel pump is the brand new one from the recall and it just got serviced two weeks ago.

kinda sounds like a HPFP but since you just got it replaced you should def. hit up terry first.

In case you missed it in your other post. I don't think the old JB3 is compatible with the new DME software. And you would need to read the code with a code reader to have any idea what the problem is. The JB3 did not have built in code reading like the JB4. Just upgrade to the JB4.
