ok so i got some money to fix my truck i put a fuel pump in and a crank sensor in, and it still did it so i let it sit for 3 weeks then i went to sell it and i drove 15 miles to meet the guy didnt skip a beet i told him what it was doing and i told him i have no clue why it isnt acting up so then i drove it for 4 days and it is starting to do it again, now when i replaced the fuel pump i looked in the tank and it looked like there where some globs the size of quarters of black stuff floating in there i didnt think they would do anything just a note, so now im not sure what to do,the check engine light came on but i didnt notice a miss or studder and i went to autozone so they could run the codes, missfire on every cylinder and catalyst efficiency code, i seafoamed it today and bought a new battery but i drove it a couple times before i noticed it missin and jumping again so

Disconnect the fuel line down by the fuel pump(no special tool needed) , then disconnect it up at the fuel rail(special tool needed), then use comp air to blow the line out.
