Which engine? If it's a quad 4 then it's a big job.

Yes. On the 4 cyl, the pump is very hard to get to. It's driven off the timing chain on the back (firewall) side of the engine. If you look at the front of the engine from the right (passengers side) you will see the pump housing, near the exhaust manifold.
GM recommends removing the timing chain cover, removing the chain tensioner, removing the exhaust manifold, etc, to get access to the back of the housing to get the pump loose.
Independent shops however have a procedure by where they don't do all that work. They still charge $500 (as opposed to $700+ at the dealer) or so though, since it's several hours work.
I haven't done it myself, but have read the procedure in the GM manual for the 99 I had.

If it's got fuel,
and it's got air,
and it's got spark,
 it must start.
You say the timing is right on, are you sure it's not 180 out?
Are you sure all the plugs are properly seated and functioning?

Just got thru changing wp on a 94 pain in the but. Did you check the battery. does it have gas.If the front end is off the ground the fuel pump may not be getting gas. will it turn over at all.
