Tbi injector overflowing with fuel

How is it overflowing? Is it spraying to much or is the fuel leaking out sonewhere?

Leaking over the top and partially spraying underneath along with quick dripping

Is it coming from the injector nozzle or somewhere else on the throttle body? It shouldn't come from anywhere no matter the fuel pressure. If it' spraying from the nozzle without the engine turning over then you need a new injector. If it's coming from somewhere on the throttle body then a gasket has failed or somehow the housing cracked.

Hmm- I think I have a bad injector I noticed this when I moved them to their opposite housings. Right bad injector to left housing and left good injector to right housing. This time right housing stayed dry but left leaked. I also noticed that I forgot to lubricate my larger o-rings.

The o rings cause leaks but it sounds like a leaky injector

Yeah I will replace and let you know.

Replaced the leaky injector and my truck is running better, although I did notice the engine tremble a little at idle. I also noticed rpm would slightly go down then pick back up to a good idle.

I replaced my injectors in my 88 4.3 and now they r shooting fule down so fast it fills up and runs up over on to the motor

Hey GURUWC9F2 did you figure out your injector problem??

Got same issue in my 1990 K1500 5.7. Injectors POUR fuel into TBI upon switching the key to run position (but not trying to crank). (everything is new) I mean whoa, almost overflowing for a quick second. Ummmm...

I am fighting injectors flooding big block chevy in 93 rv. Have changed MAP/TBS/Engine temp.sensor/Plugs/Wires/Distributor Cap and Rotor. So far nothing changed. Injectors spraying excess fuel into throttle body. Any help would be appreciated. Cant even find ECM.

Electronic ignition module in the distributor is bad
