So, just about 2 months ago. My Blazer wouldn't start on the first try. i turn the key. it trys to start but won't. My first though was the Fuel pump, but once it's started it has no issues. it runs just fine. it just takes a few tries to get it to start. Any ideas on how to fix this issue? i can post a video if that would help.

 

Turns out it was the little hose inside the tank that connects the pump to the outside of the tank, it had a little leak in it. Tried to fix it with different hose. but the pump just blew the hose off once it was in the tank. Secured it with hose clamps and everything. so now i'm stuck having to buy a whole new fuel pump assembly. Because the part is "Non-Serviceable"
