Long Crank When Wet

It just rained for the past few days at my house. I have noticed that everytime it rains and my car sits overnight/ or a long time that is takes a while to start. Sometimes I have to cycle the ignition 3 times while pumping the gas. I know I have a code 54 and that could be part of the problem. But what gets me is why it only does this when it is wet. And when it finally starts it runs like crap. When its dry out, sometimes my car fires right up and then dies. It doesn't do it that often when its dry out though.

Re: Long Crank When Wet

What's code 54?
Usually hard to start when wet is a bit of moisture getting into the distributor cap. Try removing it and drying it out, and/or replacing it along with a new rotor.

The distributor and Rotor are brand new.
Code 54 is low fuel pump voltage. But this is a intermintant problem with my car. I cleared the code 2 days ago and it has not come back yet.

Re: Long Crank When Wet

Ah, perhaps a loose fuel pump connection?

Re: Long Crank When Wet

Ya, it seems to obviously be that fuel pump problem...sounds like it matches your symptoms there eh?
