First make and model would be a big help .check to see if you you have power to ingnition sys if so check to see if spark plugs are firing if all checks out proceed to oil pressure sending unit if you have no spark check crankshaft sensor this will get you closer to finding out trouble and by the way new fuel pumps can go bad just a thought

SOURCE: no power to fuel pump relay

I am not positive how the electronics are routed on a later model truck but I had this same problem on my 89' with a 22re. It turned out that the oil pressure sending unit was in the fuel pump circuit so as to not allow the engine to start with no oil pressure. I changed my sending unit and the truck fired right off. Hope this helps.

my 1990 toyota 4wd manual tranny wont go into 4wd.
the 4wd light does not come on but the vehicle feels like it is in 4wd, is there a electrical switch that controls this issue ie; the hubs don't lock in.

check your fuses or the fuel relay which are located in the fuse box either by the drivers side or in the engine compartment,
