about 2 weeks ago i went to start up the suburban to leave to work. started it went inside to finish getting ready and came back out to leave. trucks not running. i tried to restart it with no luck, could smell lots of fuel. popped the air cleaner off and notice gas everywhere, on the intake and tbi just flooded. didnt have long to look at it until after work. thought about it while at work and ordered a tbi rebuild kit. i figured either the mani to adapter gasket or adapter to tbi gasket was shot and if im going to tear into it that much might as well rebuild the tbi. both gaskets were well overdue to be replaced, tbi wasnt too bad. hooked everything back up and still no start. at this point it is day time and i can actually see that the tbi above the throttle places is filled with gas and seems to be seeping out onto the manifold. just a mess. seems like its been doiing this a bit. ive been smelling a slight gas smell for a few months. ive replaced the coolant sensor, tested the map sensor, tried a different ignition control module, verified i have spark. surely i am overlooking something. the truck has been running fine u to this point, never any starting issues. there is no check engine light. just dumping fuel into the intake! 1989 r2500 suburban 454 7.3l tbi automatic.
