Fuel issue...your opinions?

[Jclgodale3]

Ok...on my 81. I drive it infrequently. Never had an issue with it starting. Parked it about 1.5 weeks ago. Pulled in the garage and turned it off with no issue. Went out in the garage to fire it up and drive it around today. It spun and spun but never would fire. Checked the carb...seemed dry with no gas fumes. Confirmed fuel in the tank. 1/2 a tank .Shot some ether, fired right up then died. Shot some more...fired right up then died. Ya'lls thoughts on the issue? Fuel fump? Pick up? Filter?

Obviously no fuel, as to why, is another issue.....

filter...pull it off there and blow through it, if it takes out your eardrums, it's BAD, if just slight resistance, well, hard to say....when wet they have some blow resistance, but when dry there is hardly any....

pump....obviously it has to spurt good with each stroke....loosen the line a tad and see if it sprays out a little with a good healthy spurt....or decent flow with the electric pump on....if you have that....

if not, maybe the fuel filter in the carb????

how about that pesky fuel line from the steel frame line to the pump on the sux side?? that a ordinary line instead of custom molded line, it could be collapsed....

then we get to the carb....ask Lars....

:suicide:

There was fuel at the pump and some fuel in the line going up to the carb when I disconnected that particular feed. Could a fuel filter at the carb go from flowing to totally clogged from 1 drive to the next attempt to start it? I would think It would have started starving for fuel on the last drive...

Pull the feed line from the car and have someone crank the engine, fuel should come out rather quickly, if not your fuel pump is kaput or you have a bunch of air in the line which may be hard to burp. I have that problem sometimes, especially with the truck. I have anti drain back valves but never got around to install one. However, with the 2 saddle tanks sitting lower than the fuel pump it's a much more likely issue on that car than on a corvette.

I think I'm going to put a new pump on it for good measure. Car has 77,000 miles on it but is 28 years old and it appears to be the original AC pump. I'll update when that is done...thanks guys

 

[Jclgodale3]

Put the new pump on it and it fired right up. Thanks guys

That's good news, a simple fix :1st:

That's good news, a simple fix :1st:

:rofl:Not as simple as on most small block cars. Damn, it's tight in there! Needed a good 2 foot extension to go in through the inner fender well to get at a couple of the bolts:rain:

It's funny how that works- you'd think as tough as a fuel pump is on a SB Vette, it'd 5X more on a BB. For some reason its not. I put the pump on Ol' Red in 15 minutes. 1/4 drive deep 9/16 socket, flat screwdriver and a 5/8 line wrench. All done.
