Some Good...Some Bad.... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Well I found the problems with the truck not starting after sitting 6 months. Turned out the fuel pump sprung a leak, as well as a few brittle 33 year old wires that needed replaced.

Thanks to EdB and his bud Robert for the help. Put on a new fuel pump and filter today and Ta Da....no start.

Ugghh. More looking and now it also apears the carb is not working.

No squirtie. Pulled carb filter and pulled carb top off and it all seems to be working OK, just nothing getting through. Tried some carb cleaner to loosen things up, but still dead. Yanked carb and I guess I try and look it over to see if it will function.

Question to our experts. anything to look for in particular. I am assuming something just gummed up and I can't see it yet.

Also if I have to replace this carb...I want to get one with electric choke...Does anyone know what year/modelS came with the electronic choke set up.

Currently I have a Rochester Monojet for a 250 CID six and it doesn't have anything but manual choke hook up (numbers said it was off a 69 250).

Some day it'll move again!!

the first thing tolook for is gas getting through the gas filter sometimes that gets dried out and gummed solid

Definitely go ahead and change fuel filter.

BTW Bill I am coming up on my monthly week off, I may fire the old GMC up and head south. Let me know whatcha doing next weekend.

I took out the filter to see if it was clogged and it looks ok...Tried it without a filter in at all and still no squirt.

Krue.....I should be around Saturday after lunch time till around 5ish. Got to take the wife to the symphony.

Far as I know Sunday afternoon and Monday I don't have any Honey do's (yet). be glad to see the GMC.

Tap the carb LIGHTLY, VERY LIGHTLY if you're strong, especially while someone else is turning the engine over. The float or more specifically the needle is probably hung up in the seat. If that doesn't work, the gas may have "varnished" over the winter. Smell the gas. If it smell like gas it's OK. If it smells like varnish you're going to have to clean the whole fuel system out.....Zoomy

I'll get up with you about easin' down there Monday!

6 months shouldn't be enough time to gum up the fuel... I fired the GMC up on 2 year old stale fuel.

I ordered a Q-Jet several years back for my '71 Chevelle. I asked for one for a '79 Z-28. It had the electric choke that I was wanting and hooked up without a hitch. Much better!!
