Well, its not the alternator, the voltage and amperage is fine. Vacuum hoses still haven't come in. I'm thinking starter.

You turn the key all the way to "START" and nothing happens for maybe 1 second. Then it starts cranking for a second and then it fires with no problem and the car runs perfectly. The lights don't dim or have any issues so I'm fairly confident it isn't the alternator, and the tests say that it isn't (Voltmeter and Autozone).

I've never had starter issues with any of my cars (even my old Austin 1200 back in Bosnia) so I don't know what to base the problem on.

Anyone have anything similar to this happen and did you figure out what it was?

I just read this post. lol

The problem is the electrical part of the ignition switch. This is the part that makes the "contact" with the starter

With constant use this part wears out and does that thing.

Mine also does it, im yet to find a second hand electrical part to replace mine. Sometimes you feel that you have to hold the key in a certain spot just to start it. :P

Hmm, good idea.

Is it the actual ignition switch (Like where the key goes in) or something further down (like solenoid)? I guess tomorrow I will open up the housing with all the stuff around the steering wheel and check it out.

The ignition switch is divided in 2, the mechanical part where the key goes in, and the electrical part.

I dont recommend tearing down the ignition switch, you can make things worse.

Ok, well, today, the new silicone vacuum hoses came in the mail and I installed them and the problem went away. Turns out it was the MAP sensor had trouble getting vacuum on start up due to the vacuum leak. After taking off the Intake manifold to MAP sensor vacuum hose I blew compressed air through it and it had a slow leak on the rubber tips, but I guess it was enough to affect the car.

Thanks to all who replied.

great :) ... i love it when people get rid of their problems (don't we all?)

i used a tiny T wrap on the tips of the rubber hoses of my vacuum lines... couldn't find decent replacmet rubber pipes for them so i soaked them in engine oil for an hour or so to make them flexable then i installed them and fastned the tips with the T wraps... works great.
