Default Sputter no Start 2002 OB 3.0

Hi All,

My OB seems to have frozen up in a cold snap here in NC. I was getting cranking but no firing at all.

The temps are up now but she still wont start.

Cranks strong, sputters for a second then dies.
I replaced the fuel filter - cheapest and most obvious part.

Is the pressure regulator next or maybe the fuel pump?

Thanks for helping!
Tom

If you're comfortable doing it, check for flow after the filter where it connects to the fuel rail inlet.

Not sure if the 6's have a schrader valve like most other cars do where you can check with a fuel pressure gauge, my 2 doesn't.

Doesn't take much moisture to cause havoc when frozen in a fuel system, any chance of pushing it somewhere warmer ?

If not, maybe get a hair dryer and warm up the fuel lines.

Once you get it started, might want to put some HEET in the tank to dry up the water.

Hi, I got the thing started again, here's my best guess..

When it got so cold, I think that condensation froze in the catalytic converter and essentially plugged up the exhaust.

I had a friend squirt starter spray into the air intake (disassembled the air box) which caused the engine to catch for a few seconds. We did that a few times until it would run at high rpm but not idle. White smoke was billowing out the back - scared me, I thought I cracked the head or something. After a little bit, the smoke cleared and the car would run.

Since my wife takes a lot of short trips, I figure that the exhaust system had some water built up and the super cold temps (not above freezing for 2 weeks) caused the it to freeze in the cat and clog things up.

I let it idle for about an hour then took it for a drive. It struggled initially but a few hot laps around the block and it was back to normal. Whew.
