03 no crank...no clicking

Here is a schematic I found just so you can see the paths. Where are you hearing the relay click? in the passenger side of the engine compartment or in the fuse box?

Hearing it from the fuse box

An do I need to hold the key as if I was starting it?

May seem like a dumb question. But I bought a digtial multimeter ....what setting do I need to use to check for voltage at the relay

Set it to DC and make sure the range is higher than 12 volts. Black to ground Red to positive.

Had the exact same issue last year. No crank, just a click. Most times, if i left it alone for 30 minutes or so, it would start. I thought it was the relay, but it turned out that it was the battery. I replaced it and never had that issue again.

yes. That should be the only time you get the voltage.

Before you actually get a voltage the meter will probably jump around below +1V (DC). That's normal. When it actually picks up a voltage you should see OL for a second then the actual voltage. Doesn't matter which pins you connect to which leads. Only difference you are going to see a +12V or -12V. Either is good. I suggest trying it on a AA battery or something similar if you want to see what you are looking for.

If you are hearing it from the fuse box it possibly indicates the relay is working, but it's better to check to make sure.

I wouldn't put it past the battery either like bertro mentioned. When it isn't working have another vehicle to jump it and try it. How old is your battery? What is the warranty on your battery (ok indication of life)? So you aren't hearing the starter click at all? Usually even with a low battery it clicks, just not turn over, but my 06 durango acted weird when the battery was dying.

So first to check is pin 85 (under relay) to the positive battery terminal (+) and have a friend turn the key and hold it in the start position or you can do it yourself if you can get everything to stay in place and be able to see the multimeter while you turn the key. If that's good (12V+), connect a lead to pin 86 and the other to the negative terminal (-) and turn the key to the start position. If that's also good (12V+), that means your starter circuit minus the relay is good. Swap relays with something that takes the same relay like your high beam relay if that's the same (something that you can drive without for the meantime). If it doesn't work that means your pcm is good, relay is good, park/neutral switch is good, and everything else in that path. There is still the possibility, like expeditionandy said, that the relay is not making a good connection and is/was causing your problem, but you should do the next steps to verify power to the starter if the relay swap didn't fix it. Pull the starter relay back out. Connect one lead to pin 30 and the other to the negative battery terminal (don't need to start). You should again see 12v+. If not check for power at the fuse (pull fuse F1.101 in the fuse box, put one lead on one of the two pins and the other on the negative terminal. Check the other if you don't get power on the first one. With the fuse out only one will get power) and verify similar voltage as you were getting before. If you have power there and not pin 30 you probably have a bad fuse or possibly connection. Swap it with another fuse with the same amp rating and check pin 30 under the relay again for power like before. If all that ends up being good and all the relays and fuses are good and it still won't start you will have to check for power at the starter which I can go into detail in case you have a bad starter.

Well I cleaned the corrison off the battery. Had it tested and charged..... the starter relay is clicking ...so do I need to check the power at the starter

Well this threw me for a loop....pulled the starter this morning ....had it checked ...tested good at autozone an advanced ....so I put her back together ...an guess what it fired right up.....started it ten to15 times....imam let it sit awhile an try it again.....hopefully. it wont happen again

I think you used the key word corrison May have been some on the starter wiring and when you disconnected and reconnected you got a better connection or possibly the starter needs new brushes and cleaned up on the armature.
