After fixing the radiator hose leak. (Knock on Wood) and the rover sitting for a few days, when I started it again for the first time the SRS light comes on, goes off then comes back on and stays on. I had no problems with this light up until the car shot radiator fluid everywhere. I searched the forum for help and it said to check you tail light, and your battery. So I check the light, no problems, and the battery had very little corrosion so I went and cleaned it off, and wahlah the SRS light went out. Now this morning when I started the car up, its on again and stays on.
What are the next things for me to check.

Also where is the cheapest place to get a landrover gascap as my SES light keeps comming on after I fill up with gas, then I get the code cleared and am fine for about 100 miles or until next fill up where it comes back on. I cant remember the exact code number, ill right it down next time but its something with Fuel Emmisions System?

You don't need a gas cap, cheap or expensive, get the exact fault code and then lets talk.
As for the SRS, most likely a dirty or loose connection to one of the front seat belt systems or a tired/low voltage battery.
