Do you have any check engine lights or anything? Did you do the timing belt yourself?

A quick description like this I would say you might have two issues. But both can result from sitting. I would check fuel pressure, if you can start the car by putting gas in it, but it won't start on its own, it sounds like you have a fuel leak, pressure issue. Clogged filter, leak down, but I believe could also result from vacuum issues as well.

The redline issue is a different one. Assuming the car runs normally once started. You might need to figure out if the RPM signal is going to the transmission.

If you did the work yourself or did not, you need to go through an verify that everything is installed properly, grounds, vacuum lines, etc.
