Fuel pump questions

[GMCjunkie]

Many of you know Ive had ISSUES with my truck starting. Well I have a date with the auto fix it guy right after spring break to get the issues (hopefully) fixed. She has been sitting for quite some time, so my son and I go to try to get it started in preparation for the trip to see the auto fix it guy and th battery is beyond dead. New battery. Plenty of fire, now it acts like its not getting fuel. I prime the carb, it tries to start, but once the donor furl is burnt, nothing. Here are my questions. How much gas are ya supposed to use when priming the carb and how many times should I try this before enough is enough? Other question, can my fuel pump go bad from just sitting? If this might be the case, can check it without removing it? Thanks in advance for your help. I got most of the interior done today, so it wasnt a total loss, but now Im aggrivated cause I cant get her to start. Thanks yall

How long has the fuel sat in the tank? Fuel can start going bad in a month.

Do you have an inline filter between the pump and carb? It could be cloged and a cheap $3 clear filter allowd you to see if the pump is working.

Kinda goes with the last step but do you have fuel up to the carb? You can prime your line by blowing air into tank wile sealing off the filler neck with a rag.

Everything above checks out u can check by removing the line into carb and cranking motor over. Obviously it shale push fuel out.

fuel pumps are like $15... might as well change it out takes like 20 minutes.. easy way to solve your question.. its two bolts and then push up the ecentric rod.. some have a threaded cap you can unscrew to shove up... ive had many problems with that too.. but i also second the opinion about the fuel filters and what not... little bit of fuel should be enough to fire it..
