hi there ive replaced cam and crank senors, fuel pump, filter and relay, i have fuel to the rails, spark as well ( fired with starting fluid) and my neighbor put his ear to the injectors and not a single one is firing. my mind is set on a bad computer but before i invest time and money into it id like to know if theres anything i could be overlooking. and if i need a new brain how much it might cost ball park to take to a dealer.
any help is appreciated, thank you.
