Before you start tearing things apart, go to your local Harbor Freight and get a $15 compression tester. Without a proper compression test you will just be chasing your tail. I would also test for fuel pressure, spark, etc. to see where you are at. If you don't have a fuel pressure gauge, pull the feed line from the throttle body, point the hose into a tin can and turn the ignition on. If it fills with fuel during the 5 second prime shot then you know the pump is working. Look down the throat of the throttle body and have someone crank the engine. The injector should pulse and squirt fuel. If it doesn't then you need to check the injector wiring to be sure it is getting a signal from the computer. you will need either a noid light or a test light to check it while cranking. If it does not pulse, find out why. It could be a bad ignition module, a bad computer, etc. and is probably not an injector if it is not getting a signal. I would also check the timing belt. These engines are non-interference so if it went there would be no damage.

Find out what works and what doesn't first before you start randomly disassembling systems. Pulling the head isn't free. On a Metro, you will need to get new head bolts ( they are 1x use) and a new head gasket at MINIMUM to put it back together ( around $100). Plus, being an XFI, it has special gapless rings that are very hard to find nowadays. So please, before you take another thing apart, do proper diagnostics and post your findings. Remember that the tools to do diagnostics are not free, but they will cost you less than the price of pulling and reinstalling the head.

Also, my car was found sitting for about a year when I got it and it didn't have a problem with the EFI.
