I have a rich running 2.8 and someone said it could be the cold start injector. What happens if I just disconnect the wiring to it?

Well, that will deactivate it, but it only has power on it while the engine starter is engaged. It is not controlled by the engine computer. If it is leaking, pulling the wires will have no effect. You'd need to remove its fuel line from the fuel rail and plug the rail to stop it from leaking, if that is what it's doing.

you should also know, IF you disconnect it, the engine will crank for awhile before starting.

Here is my thread where I was chasing a rich fuel condition. Hope it helps.

The Coolant Temperature Sensor could also be suspect even though it hasn't set a code. If it is sending the ECM a message that the coolant temp is cold, the ECM will add more fuel to the mix. My 87's CTS failed all at once, causing clouds of black smoke to roll from the exhaust. A scan showed the coolant temp information to be below zero, even though I'd just driven the car into the shop to be checked.
