Some comments and questions before ideas:

Please turn off caps lock and observe netiquette

How many miles is "quite a few?"

When you say replaced "usual tune up parts" what exactly was replaced and
how many miles ago?

What brand tune-up parts did you use?

How did you check the fuel?

When it is rainy or cold and the engine cranks but won't start, is it hard
starting whether the engine is warmed up or cold?

There are several things that can cause the difficult starting but the
answers to those questions will help narrow down the possibilities.

Well Ray..has 112,000 miles..replaced plugs (ngk) cap and rotor, fuel
filter,air filter,(aftermarket)checked fuel at cold start injector fitting
for pressure,starts easily and runs fine when dry or warm. when cold or
rainy..cranks and ocassionally will fire but not run. Had problem before
parts were replaced.Just started doing this one day!I have introduced fuel
through pcv hose..and checked spark with old plug with increased gap and
looks good. I am a mechanic so I am not guessing.I feel it is electrical?
Thanks!

Change out the plug wires with a new set of Toyota OEMs.

I drove a 88 work truck that always ran and started fine unless it rained over night.
If it rained then the next morning it would never start. The problem it had was the
moisture at distributor wiring connector. By just unplugging it and plugging it back
in the truck would then start right up after that. I drove it for at least a year like that.

Maybe if your lucky jiggling the wiring when its refusing to start will turn up something
like that as well.
