new fuel pump in front tank, new ECM, pulled code 542. still not getting fuel

already did that...please help?

Is the selected tank - fuel pump running when key is turned on?

Pump doesn't prime up brand new just put in

Check for battery voltage at the inertia switch when helper turns key on.. Should have it on both wires as key is turned on... IF no voltage .. Possible relay problem... If voltage present.. Check for voltage at pump connector and tank switching valve. .. Check ground lead at battery negative terminal.. It's a 12 gauge wire hooked to battery cable and going to radiator support... This ground lead has GOT to be making contact!! I guess you've tested 'ALL' fuses(?)

Already checked the voltage...Haven't had the chance to check anything else yet...it has to be something with electrical because when we first put the computer on it the pump kicked on and there was gas in the line and the hand held computer freaked out...shooting started fluid in the intake she will fire up and run until the starter fluid burns off and then she dies...help
