Ok..been trying to get my 79 GT running.... with MUCH help from VintageRob, we've got the thing starting reliably...it's adjusted to what we think is spot-on (he's got lots of experience tuning his 77 Alfetta GT...even changing out pumps and engines, so I trust him. He knows the procedures and Wes's manual very well.)
So it starts, it idles, it warms up...it revs stationary. But when you drive it, it has absolutely no power. We had everything like it's supposed to be pending a test drive and a mixture adjustment. So I drive it and it's just gutless.
Couple facts: The fuel pump is strong and comes on well. The low fuel pressure light gives me a sub-second flash upon first start and stays out for good after that.
So we start to adjust the mixture--as we turn to richen it up...I drive it again. No change, we start turning more, no change....turning more...no change.
So matter how "rich" we attempt to make it, there is no change...the car is just gutless, even when floored it will hardly make it up a hill. The motor otherwise seems solid.
Since the behaviour didn't seem to change when trying to change the mixture, we're thinking that the SPICA pump on this car is nearly totally failed. Since the fuel pressure seems good, starting and other behaviour and adjustments seem ok--just no power.
Any other thoughts before we start changing out SPICA pumps?
