Re: Ordered the Holley Sniper

Well time for an update. Had a problem with the system not seeing the distributor and traced that to a pin in the MSD connector that was not seated and when I plugged it in the wire pushed out the back. I did get it fired up and running for a bit. Then it shut off. Checked everything in the world and Holley tech was good at helping trace the issue. Gave up and went home and cut the grass. Went back yesterday with the next round of things that Holley wanted checked and all that looked good. Hit the key and it fired up. But it only ran till it got to about 140 degrees of water temp and shut off. Back to looking at stuff. The only thing I had not checked was the fuel pressure from the tank. With the Boyd welding tank and the Stealth pump it should easily make 60 psi but you never know. Hows 120+ psi. When I did the test it pegged my 120psi fuel pressure tester back around to the needle stop. So I cracked the return line to see what was up and no fuel. Back on the phone to Holley and it is the internal regulator is stuck. With the huge fuel pressure it could not cut the fuel back to meet the afr and ended up just to short of a duty cycle on the injectors for it to deal with. All the parts are on the way and I am going to pull the throttle body off tonight and have it ready for the regulator replacement as soon as it hits the door. Holley has been good about working with me on this. Really need my 66 back up and running. Driving the duelly is just not the same.
