Idle Air Control Valve

Thanks for the reply. Well actually the truck starts then stalls in about 5 seconds. It will do this repeatedly. Someone on another board said it may be the Idle air control valve is getting stuck and that a couple of taps on this valve may knock it lose temporarily. The truck used to making a woooooing noise everyonce in a while. I guess a better way to describe it was like a REALLY sick sounding horn. I thought the noise and the sudden problem may be related.

Well I went out checked the resistance across the pins (both ways ) according to the Hayes manual. It is supposed to measure 6 - 10 ohms. It measures 0 ohms. I turn the key on I can feel the solenoid click but I can't see the plunger move. Its only $40 so I think I will take the chance. Hopefully this will sove the problem. I don't have the spare $ to spend at the dealer right now.

It starts then stalls within 2-5 seconds. It doesn't matter if I give it trottle or not. It still stalls. It will start & stall like this all day long. I changed the fuel filter no change. You can hear the fuel pump run but I realize it still may not have enought pressure. It seems to me that it would at least idle if the fuel pressure was low.

It could be a hose off (or hole in one), bad brake booster, EGR valve stuck open or intake manifold gasket.

So would any of those problems put out an error code that I could read if I had a scanner?

The EGR might give a code but do not waste your money on a scanner.
Just go to:

And can you pull all the codes you want.
Unless you buy a hi dollar scanner ($1200.00 or so) the cheap ones for $50.00 are only the same flashing light as your MIL on your dash.
