Hobbs switch needs a Vac Source & I "think" mine is tapped into EGR line (which I don't use anyways) or any good place to put a T in the line. Not sure it might need a power source  but my memory is poor! Altho it seems to me that it has a Pos-Neg plug on the bottom??
I'm sure many here can explain better!
Pretty basic stuff & trust me I am NO Electronics wizard!!
I'll look tomorrow if nobody responds by then.  :cheers:
 
PS: The Hobbs switch only actvates 2nd pump under boost so it may not be an issue for just keeping the car running.

I'm pretty sure it's both pumps running at the same time.  I have to install that Hobbs switch.  Once I do that I'll get back to you and let you all know what's up. 

Just need to find some instructions on how to install it.  Hoping that William will chime back in.

Bob, I used the a stock balancer and used a measuring tape to make a mark for the 25 degree spot, than filed a small slot there so the spot would never be lost. You hook the Hobbs switch up to a vaccuun/boost hose and than wire it into the second pump. I'm sure there are directions on here as to how far from the TDC balancer mark to make the 25 degree ATDC mark and someone here most likely has install directions from Racetronix as to how to wire everything up including the Hobb switch or go to their site or give them a call. I did this stuff a long time ago so this stuff is not fresh in my head and I would not want to give you any bum information offhand.

If you have a stock balancer I would double check to make sure that the one you think is TDC on the TA balancer really is. Look at the crankshaft key slot on the stocker and where the TDC mark is in relation to it, then compare it to the TA balancer to be sure you are using the right slot on that balancer for TDC.

Success!  I was reading on the Racetronix site how the two fuel pumps are jumpered to run at all times.  I removed one of the jumpers and the car started right up and continued to run albeit it was still running rough.  I only ran it on 3 occasions for about a minute or two at a time.  There was a lot of smoke this time, it literally filled the man cave.

One thing though:  The fuel gauge still read 80psi when the fuel pump first kicked on to build pressure.  When running, the gauge was at over 100psi.  However the car kept running this time. 

I'm thinking that the fuel regulator spring is sprung.  I'm going to replace that next.  It is very old, I can't even remember where or how I came to it.

well, at 100 psi, it is getting 52% more fuel than it is supposed to at idle....it will not run properly like that and it is probably filling the oil with gasoline which would mean, I would change the oil before running it anymore.  Cannot be doing the cylinder walls and rings anything but bad things

Might be the thing to do is replace the regulator.  I do not see how both pumps running at one time can do anything but flood the engine as the regulator cannot handle the flow as Bill said.

Roger, I'll be changing that oil and filter first thing today.  I'll get that regulator on order first thing in the morning.  Good thing I was using Amsoil, hopefully it gave it enough protection to cause little harm.  I won't be starting it again until I get that new regulator on.  I'll also get that Hobbs switch figured out and installed as well.

Steve and all others:  Thank you so very much for helping me out.  I truly appreciate your help and especially your patience with me.

If the regulator does not work check that the fuel return line is OK, not plugged, etc.

Roger that Will.  Thanks.  I'll let you all know how it turns out.  I'm thinking about heading down to Gbodyparts and picking up that new regulator.  It will save the time of shipping.

Well, I finally went to Gbodyparts today and got another fuel regulator.  Put it on and the fuel pressure came up steady and slow until it stopped at 43 PSI.  Hit the ignition and it fired up right away and kept running albeit a bit rough.  There was no smoke this time.  Not one bit.  The fuel pressure gauge still reads high.  I then shut it down.  When I went to start it a second time, the fuel gauge read high, around 65 psi and then went back to 43 psi.  I started it and again, no smoke.  While it was running rough again, I revved it a couple of times.  Again no smoke.  However, I noticed a liquid started spewing out from just behind the driver's side head light.  I immediately turned off the engine.  It was gas.  I killed everything and pulled all power from the garage.  I have a fan running to get the fuel to evaporate. 

The fuel was coming from the vapor canister.  I pulled the hose that hooks to a fuel line.  It looks like was coming from there.  The only thing I can think of at this point is Bill's advice to look at the fuel return line to see if it is plugged.  Not sure how it's plugged since all fuel lines are new.  PFM I guess. 

So, what would be the best way to check to see if the fuel return line is plugged, and how to clear it? 

Thank you all for helping me out.

I removed my vapor canister, and at the hard line end located on the side of the frame rail that goes back to the fuel tank from the canister I installed a 90 degree fitting which connects to the hard line with a short rubber hose to point down towards the ground so no dirt can plug it. I thought about using a fuel filter at the end of that hard line but decided against it. The electrical connection to the vapor canister I just tucked away somewhere if I remember correctly.
I am sure someone on here can tell you why the vapor canister filled with fuel and if I got the electrical part right if you want to remove the vapor canister.

One thing you can do easy is just see if you can blow air back though the return fuel line one way or another. I would use a piece of rubber hose over the return line and use my lungs. if you can not, its pluged for sure but if you can it still may have some kind of restriction like a kink, etc.

Hey Bill, thanks.  I'll be checking out that return line as soon as I can.  It might be a week or so though.  I have the wife to take care of so I'm going to be out for a bit.  I'll let you all know what's up. 

Thanks again.

You know, thinking about it, I might just have the return and fuel vapor lines hooked up wrong.  I'll be doing some tracing tomorrow morning.

gradually working your way there...it is easy to mix the lines up at the tank....
