'92 4.9 fuel/computer trouble

Posting this for a friend who has a problem with his truck. 1992 Flareside, 4.9, auto trans. Short story, not getting fuel on cylinders 1,3 and 5. All injectors have red common wire, odd cylinders have tan wire, even cylinders have white wire. Checked all wires from injectors to ecu computer harness and all were good. Decided to attach a jumper wire from white wire to the tan one and ran the truck for a little while and it runs great. Question is, does this mean it has to be the ecu? He has ordered a new one from the part store and it won't be in until Tuesday. I would hate to see him spend money on a part he doesn't need. Any thoughts? Thanks, Paul - OzarkCountry
