Ok thanks man, I'll check it out this weekend and let you know what I find and yeah I know about the fuel cap, all 3 were green diesel caps and I got 1 from autozone than from advance and than one from napa and they all hissed so I got this special vented one that u turn right before you start it up and it releases all the pressure and u leave it open while u drive and u close it when it sitting for a tight seal.

 

Ok update what went down this weekend, the ignition switch is all good and so is the fuel shutoff solonoid, turns out that it was a clogged return line that which was pressurizing my tank and stalling my engine due to excess fuel. Thanks a bunch for ur help, muchly appreciated

 

hey guys, just give u an update on my problem, so i cleared the line and it worked just find for 2 days and started stalling again. so i do a little research and they say something about the sending unit. so a skip, hop and 2 weeks away, i took off my bed and and replaced my sending unit( which was the original sending unit) and now it runs better than ever!! thank u guys again so much for your help, u guys r awesome
