Need a GM Mechanic help with Chevy TBI

[blackgn1]

Got a 1991 Blazer I'm working on the fuel system. Fuel pump is good. Has a new fuel pressure regulator. When the ignition key is turned the fuel pump engages. The problem is that the injectors fill the throttle body with fuel. Fills the bowls. Even with the electrical plugs unplugged the injectors still fill the bowl. Not sure but I think the injectors are stuck open. Don't want to pay $150 for new one if there are other possibilities. Thanks for any help.

Get a used one at a salvage yard. Sounds like the injectors are fubar. Phil.

Injectors are screwed. If you can wait on getting them back contact Chuck Leeper (sp) on the board and see how much it will cost to clean them. Other than that you might get lucky at a scrap yard.

Thanks so much guys. I was thinking they were shot also. Hey Charlie the Regal is fixed!!! Put the ohm resistor on and problem solved!!

Glad to hear it was that simple. Make sure to get a complete gasket and pressure regulator kit when you do it or you'll have some issues Later. Learned that the hard way.
