Pulled a plug from No5 cylinder and no spark.
Replaced plug wires (found a cracked one) and replaced the EGR
solenoid - it was bad.
Could smell gas (faint) from cylinder where plug was pulled. I found
the schrader valve (?) - pass side of throttle body, at least I think
that's what it is.
No loose vaccum hoses.

Good to know..................
But did it fix it ?????????????
Other plugs sparking ok ????????
Did you had fuel pressure @ that valve ????????
Do you hear the fuelpump buzz for a couple seconds when you turn ignition on
?????????
Do you have gas for sure ????????
How fast does it crank ? battery still good ????????
Under about 9 volts engine will crank slow but most likely wont start.....
Try starter fluid or t-body cleaner and squirt some in the intake/t-body, if
it's trying to run it probably is nt getting any fuel

OK, if you don't have spark none of that other stuff matters, it ain't
gonna start or even fire. I think there is a relay for the ignition
system, it's with the fuel pump relay. You might swap that with another
of the same part number. That's the only easy thing I can think of to
try.
If it's not that, maybe someone has a troubleshooting procedure for the
ignition system. You'll need to go step by step to find the origin of
the problem. I know that the crank position sensor has caused a lot of
people trouble...

I had a similar problem on my '97(same engine as yours)--would crank but no
spark. I removed and cleaned the crankshaft position sensor and replaced
the battery and it's been fine ever since. I think the problem was the
battery--enough voltage to turn the engine but not enough to get it to
spark.
