Hi I have a 1989 1500 with a 350 just put a crate engine in it and I resealed the TBi but left the old injecters. I went to start it tonight and the drivers side inj just keeps pouring fuel causing it to flood. I switched the wires from side to side no difference. I also replaced the diaphram in the tbi so I think it is the injecter. Any thought??? Thanks

Injector is leaking, replacing it is the only option before you ruin the engine with fuelwash....If it was me, I would replace all of them and be done with it, wouldn't want to void the engine warrenty and with gas prices so high you'll be better for it in the long run with no other worries about fuelwash problems.
