Quote: First check for spark to spark plugs.
If you have spark to plugs then jumper the fuel pump prime conection or see if it has 12 volts on it when no start.
If jumpered or it has 12 volts on it the fuel pump should run.

It does not have one on yours but does have a extra fuel pump balance fuel pump on frame and a fuel pump balance module and fuel pump relay plus the oil pressure switch that shold turn on fuel pumps after oil pressure comes up and a bunch of extra crap.
Good factory service manual or a all data sub would be in order to check it out.

If you need it I can post a pdf wiring diagram on it later.
5.7 engine right?

From what I get out of the repair info on it the balance fuel pump is used with the dual tank set up.
Let us know how it goes.
Good Luck

ok, i checked voltage on the prime connection, got about 4 volts on start up. i took the relay off and had 11.8-12.9 volts on the relay connection.
so im thinking the relay is bad. im gonna find out. damn i hope it works.
