Hi there,

Today I was driving into work when a freak snowstorm shut down I-84 in CT for about four hours. While in traffic, my Jetta seemed to run fine...no lights, smells or shakes. Finally, traffic began to move again and I drove ~25 miles to my final destination.

I parked in our office's heated garage (~50*F) during the day but when I returned in the evening for the commute home, my car wouldn't turn over.

Cranked fine and it sounded like it had intentions of turning over so I think the starter/solenoid is in fine shape. So I immediately thought fuel delivery... I mention the garage is heated so I highly doubt fuel-line freezeup but I did attempt to dicpher the silly fuse box icons to locate a fuel pump fuse. While I can't be sure I checked the proper fuse, I did pull all the ones related to the engine picture and they were fine. Checked the relays under the hood for any smell of arching, also seemed fine.

I'd rather have some of the boys at the office take a look at it instead of having it towed out of a parking garage...but not sure where to start.

Do you think it's a fuel delivery issue?

Perhaps a computer issue from idleing so long? Check engine light didn't turn on during the morning commute.


Did try turning it over in 'neutral' as well in-case it was the neutral ignition switch acting up which has happened in previous vehicles. Same result.


What do you think?


Thank you,

Brian

Brian:

It could be a fuel problem. Did you notice if the engine overheated while sitting in traffic? Also, what I need you to do is check the engine for both spark and fuel. Here are the how to's for doing both. Check them and let me know what you find.

Check that and let me know what you find. Also, a gauge will be needed for the fuel pressure test. Most parts stores will lend or rent them.

Let me know what you find and thanks for using 2carpros.com.
