Bad Fuel Pressure Regulator, OK to Drive?

[peteando]

99 blazer, I had hard starting just like so many others here, and had McCarthys run a diagnostic, sure enough bad fuel pressure regulator. My question is, even though it takes awhile to fire up, it runs fine after that. Can I drive around like this without harming the engine until it gets warm enough out to fix the part myself (MN)? THANKS pete

And burn out a stater in the mean time and drain your battery?

I was thinking more along the lines of dumping fuel into the oil=farked bearings=engine rebuild=expensive when compared to the cost of a new injector unit.

He has a 99.

I understand that, he still has a central pod where the main regulator disphram is..

True, but I have yet to hear of them leaking into the cylinders.

A rich condition can also kill another expensive part like the catalytic converter. It makes it work harder, and any unburnt fuel that makes its way into the converter, is burned inside the hot converter. This leads to the converter melting and plugging up.

The computer can compensate for some things, but if the fuel pressure is just too high and the computer can't cut back on the injector(s) duty cycles enough, I would think the catalytic converter would be at risk.
