99tahoe wantstart unless gas is poured in throttle body

SOURCE: fuel supply

sounds like there is no power to the fuel pump while cranking. check the oil pressure sender this helps the fuel pump run under cranking

SOURCE: gas is flooding thru throttle body when trying to start

eather o-ring is bad or throttle body injecter is cracked

SOURCE: 1988 nissan pickup engine rotates but does'nt start.

IF YOU HAVE CHECKED THE FUEL PUMP FUSE AND RELAY AND THEY ARE BOTH GOOD THEN THERE IS A GOOD POSSIBILITY THAT THE FUEL PUMP HAS GONE BAD. YOU MAY BE ABLE TO GET IT TO PUMP ONE MORE TIME IF YOU BANG ON THE BOTTOM OF THE FUEL TANK WHILE SOMEONE ELSE TRIES TO CRANK THE ENGINE. IT MAY TAKE A FEW TRIES TO GET IT TO START, BUT THIS HAS WORKED NUMEROUS TIMES FOR ME. IF THE PUMP DOES TURN IT MAY NEVER RUN AFTER THIS, SO FIGURE OUT WHERE YOU WANT TO TAKE IT TO GET IT REPAIRED. THE TANK MUST BE DROPPED TO REMOVE THE PUMP. HOPE THIS HELPS. GOOD LUCK. THANK YOU IN ADVANCE FOR AN HONEST RATING AND FOR USING FIX-YA

SOURCE: only starts when pouring gas in throttle body

Tried changing the fuel filter? If that's not it it could be a bad pump
