my buddy borrowed my van & let the somma bitch run out of gas. we tried to get it cranked after putting gas in it but it never would. i had it towed to pep boys & they said the computer fuse(ECMB) was blown. he replaced it & it cranked right up.... later that evening, it started blowing again. i need to know whats causing this. does the fuel pump cause that when its going bad? the mechanic at pep boys told me because we kept spinning it over & over to get it cranked, thats what caused it....... i need an answer
