Re: tbi mystery.gurus needed!

If the injectors do not drip any fuel when you run the fuel pump with the injectors unplugged, then the problem is very likely the coolant sensor that the ECM monitors or the wiring to it.

Make sure there are no broken ground wires at the front of the intake.

I would take a scan tool and look at the coolant sensor temperature.
