pull the plugs and check them and see if they are wet........unhook the fuel line from the engine and then unhook the line from the front of the fuel filter and blow air thru it.......sounds like trash in the line

Some times there is more than one fuel filter


with out more info it could be severl thangs need to cheak fuel pressure and see if it is hold curect fel pressure fuel regulater may be bad


Might be the fuel pump relay , the canisters the pump sits in .tbi., fuel injecters...an for the sputter....coil pack


Several things to check, You need to measure the fuel pressure during cranking. Possible faulty installation of the fuel pump, bad wire connector at the fuel sending unit or bad ground on the frame for the fuel pump.Check the MAF sensor first. Have seen this before, make sure it is not broken and if it is not, bring it to Advance Auto ( Or similar) and have them check it out. Could possibly be very dirty, like mine was.
