Yup - same mistake I made - I assumed that 2001 Geo LSI meant a Tracker, but as soon as I saw the picture, I recognized it as a transverse mounted engine and realised it was a Metro. From the valve cover design and coil packs, I know it's a four cylinder engine, as well as which of the four cylinder engines (there were two used in the Metro) - in this case the later model, which is the 16V.
Back to the original problem - it's got compression, so the timing belt is probably good - 165psi is a tad on the low side, but not excessively so, especially since it would have been taken on a cold engine - the problem is going to be either no fuel or no fire - I would check for spark - remove a plug #1 is the easiest and hold it against the head and crank.
