Walbro 255 Install/Car Shut Off

[Steve Wood]

Quad Air The mans name is Red Armstrong 1-440-235-3232 great fuel pumps.

Dan, you believe that Red is not just buying a pump off the shelf and grinding the name off it so you won't know what brand it really is?

Steve been running a double pump system from him for 5 years or more and never had a problem, was just a thought.

we seemed to have a lot less fuel pump complaints a few years ago....Now, I am not sure any brand is as good.  I had a 307 last about 20 years before it got loud and scared me   On the other hand, it replaced a pump that was loud one day after it was installed...bo th came from Red with a piece of wire jammed into the bypass valve to raise the bypass pressure way up

Thanks for the info on the pumps Steve.  Now you have me thinking I'll just run this Walbro until it dies...
 
I just got finished puttin' the tank back up and adding the juice back in that I pumped out.  Hooked up all my wires, and low and behold we have ignition..    Steady 44lbs of pressure on the rail, and a nice smooth idle.  Let it run a bit before I put a beating to it.  Ran well for a few miles so I parked it and called it good.  Now I have to install the new DP that has been looking at me from the bench while I played with this fuel pump issue. 
 
Thanks to all who chimed in on this thread, and my good friend that helped me sort out the "what wire is supposed to go where issue"

did I miss what you did to fix it?  I thought about the fact that there are two different harnesses available depending upon which factory arrangement the car came with...but I was going down the road and did not try to post

[Steve Wood]

okay, I see the what wire where bit...   sounds like it was wired for the other factory possibility... first thing I did was to see if the hot wire and ground coming out of the connector matched up with the power and ground from the front of the car....I am guessing they sent the other harness but a paperclip will fix that

glad you got it this time

[Joel Russo]

I guess I got the "other harness " but I never knew I had an option..  Probably a blessing in disguise as two of the three wires from the pump to the bulkhead fitting pulled right out of the terminals.  Would have vibrated off in short order.  I soldered everything tight and ran a few continuity tests to put the right wires in the right spot on the plug. 

[Steve Wood]

I could not find the in tank harness on their site so I sent an email asking what to order...no answer as of yet.  Last night, I found the complete assembly which I think is all he sells even tho he lists individual parts for the assembly when you order the complete version and it has already been shipped.

I wish we had an alternative.  I will solder the pins when it gets here.  I am getting too damned old to enjoy dropping the tank all the time.

He does mention on his site the difference between the two harnesses...do n't recall if Eric has that info on his site, or not.

Happy to here you got her up and running and she working good. And you probably got really fast at the re and re of the gas tank lol. Cheers steve

Guess I will have to drive mine a bit to see if I found the problem because it won't fail in the shop.

Before I dropped the tank, I decided to follow my own advice with regard to troubleshootin g.  I was not getting fuel pressure on PL so I was guessing the fuel pressure was dropping....fi xed that and so far the fuel pressure seems fine while running for 45 minutes in the shop and getting it good and hot.

Studying PL, I noticed that cell 1 on the SD chip was showing 0 instead of 128.  That is wot fueling about 15 psi.  Not sure how that would affect cruising and low speed but I reset it to 128.

I guess I have to go drive the damn thing and see if I get stranded or the problem shows up again.  I always hate these kinda problems because I wonder for two or three years if it will happen again
