Now you of course may have a totally different problem since you describe trouble with the tach and fuel guage.
I gotta get after it because it gets 25mpg, vs my duelly that gets 10mpg, and my El Camino i don't even want to talk about it's milage. Like you said it sets a lot of the time sometimes not driving it for a couple months at a time and then maybe a few miles at a time. i was thinking that i would change the pump out as a first deal, it's pretty easy on the vette, 1 hr. max, and maybe the sending unit on the gage might be rusted from condsation from just setting. In reality i've had the car for 9 years, and have only put 11,000 miles on it.
