Well, if that's all the high it got I don't think it would have fouled up connections like at the fuel pump...but it really sounds like something electrical got wet, worked for a while then corroded enough to fail.

 

Are you talking about the charcoal canister on the passenger frame rail?

 

What trouble codes are you getting?

Have you confirmed you have good fuel pressure yet?

 

Have you tried disconnecting the exhaust, or tried a different set of cats? Could they be clogged? Same for the muffler. How are the O2 sensors?

 

About the error codes, P1884 seems to be the most consistent.

I went to O'reilly's and rented a fuel pressure test kit, not a single adapter in that kit would fit the test point, which the cap from screws onto and regular bike tire. I'll need to find another kit somewhere that actually fits this fuel system.

I don't believe anything in the exhaust system is clogged as it ran for weeks, my only issue was I that I couldn't floor it. When it starts now I have good flow for a second from the exhaust, very noticeable after squirting some oil into cylinder #3 for the compression test. I was pumping out white smoke for a little bit.

I have a new set of o2 sensors I'll try today.

 

OK- These O2 sensors in the front. After being submerged for so long, and probably being the originals, they are not even budging! I've soaked tem in pb blaster, but they are seized like nobodys business. Any tips?

 

Buy a map gas torch (yellow bottle) and heat the hell out of the base of it and where it threads in to. Heat is much more effective then penetrating oil.

 

-Put some vise grips on them and clamps it down really tight. Use a hammer to try and break it loose.
or
-You can cut the wire on the old sensor and you might be able to get a deep socket on it.

 

I bought a deep socket just incase but I'm afraid of cutting the wire and still not being able to get it out. I'll try the heat first!

 

I cut the wires off my sensors and put the box end of a combination wrench on it. No chance of slipping that way.
