So I'm working on an '85 T-bird w/ a 3.8 TBI engine, or CFI as Ford calls it. Engine starts and dies, regardless of what you do with the gas pedal. Timing chain is good, new plugs, good wires and cap/rotor. New fuel pump, filter is clean and flows good, new fpr. Has spark and the fuel injectors spray even when it dies. It acts like it starts and then runs out of fuel, even though the injectors are still pulsing fuel in. Fuel pressure is 38-40 psi. Tried advancing and retarding the timing, made it worse.
But, if you spray brake/carb cleaner in the TB, it will run, and it runs good.
I'm thinking the injectors are not spraying enough, although they are clean and look like new. Bad injectors, or bad computer you think? Or is it possible that a bad sensor could cause this? I unplugged the TPS sensor, didn't change anything.
Normally I can find what I need with Google, but I can't find an answer to this one. Nobody really fixes the 3.8 cars I guess, they either junk them or swap them.
