I'm usually asking about problems that I constantly have with my Isuzu Rodeo but finally old faithful has let me down. My 98 ram has never missed a beat until last year when the fuel pump died on me. I had it replaced and everything has been great until recently when I noticed that if I have left it out overnight in damp conditions then it just won't start in the morning. I have inspected all cable and they are in good shape. Has anyone had a similar problem or advice as to where I should be looking.

Thanks

Won't start? Does it turn over at least, or just click? What's happening?

Sorry for the lack of info. The engine turns over normally and it seems that it floods as well. I say this because the only way to get it going again is to leave it for a while and then start cranking it with the gas accelerator to the floor. When it finally starts to cough a bit I will have to do this a few more times and then it will start very rough until the excess fuel is burned off. After this happens it runs like a charm.????

I noticed someone elese talking about an IAC valve. What is this and could this be a factor.

I recently had problems starting and keeping running my 5.2, the fix wa to have the trottle body cleaned, this did the trick, runs like a champ now, good luck.

It shouldn't be the IAC. That's idle air control. You can't even get it to fire up without the gas pedal on the rugs, right? I bet it's your throttle position sensor.

Slantsixness might have something to say about this...

correct me if I am wrong, but, I believe that your TPS is bypassed during cranking and is only powered by the comp after ignition is recognized. You could have a problem as simple as condensation in your distributo cap, or bad ignition wires.
Just an idea

yeah....i was thinkin u might have a crack in ur distributor cap....even the slightest little hairline crack....maybe even one so small u can see it will let moisture in and it will make it sputter and start hard till all the moisture gets evaporated outta there

I think you are not getting spark. Have you checked. Plugs, wires, distributor.
