The car died, and had no fuel pressure. I have replaced the pump, screen and filter, but now get error codes 22 and 66, which seems to indicate the manifold air pressure and mass air flow are off. I have going to check the tps settings now. I have had miss and weird idle randomly over the past couple of weeks, but it only lasted a minute or so. Anyone seen this before???

injecters? do you have a fuel pressure regulator?

I assumed the error codes 22 and 66 were mass air related. Are you telling me it is fuel pressure it is looking for? I have no fuel in the regulator vacuum lines and pressure is steady for a few hours on the inbound fuel line and rails. Wouldn't it drop if the regulator diaphram was ruptured?

Turned out to be the TFI. Took it the Autozone and tested. Failed on 4 of 5 functions. Runs like a champ Now.
