Engine problems from electrical issues :(

So Dynojet sent back my powercommander to me saying everything is A-OK with it...

Yet, when it was disconnected, everything worked fine...

This leads me to believe it's either @ the injectors, which were all cockeyed and goofy because the PCIII doesn't have the proper clip to hold them in place like the oem ones, OR perhaps it's something else and unrelated, like the BAS.

Suggestions/tips/help is greatly appreciated.

I'm going to plug the PCIII back in and see if it fires up... if it does then I'm goin to wiggle the **** out of the injectors. If that doesn't work then I'm pointing a finger at the BAS.

Now, if it is the BAS, how would I test for this?

TIA

When there was no PC on the bike evreything worked fine
yet when its on the bike you are having issues i will take
a guess its the TPS ( Throttle position sensor )connection
that is causing the problem and not the injector connections

The PCIII detected and displayed TPS information extremely accurately when connected. I was actually shocked at how accurate it was when interfaced with my computer.

Ok so I just reinstalled the PCIII and gave the injectors a good tug and twist to each. Don't think the loose connection is there...

Which is very annoying to say the least since the problem is even more hidden than I thought.

There's a lot of talk about the BAS, so I was wondering... How can I test if the BAS is bad?

Since the incident I've taken off the front end and reconnected it... so it could have been simply a poor connection... but I'd like to test it nontheless.

Any help appreciated!

TIA.

When you turn the key on do you hear the fuel pump prime ?
if you do then your bas sensor is connected correctly
and should look like post # 17 in this thread

if not then its upside down simple as that

Fuel pump has always primed.

BAS is connected correctly.

So the question then is, what could make the engine die and not start if it's not:
the battery or the connection
the PCIII
the BAS
the injectors
the fuel pump


Edit:
The only thing I can think of... is that when I took apart the front end I might have wiggled the BAS and subharness connections back into place or something and that's why it works now?

Very frustrating... I'm thinking about just returning the thing to stock and trading for an 08' but I have so much time invested in this bike I'm attached. That and I don't want to pawn off my problems.
