OK...Here is an update...
As mentioned in other post..car started this morning...Ran very rough for a couple of seconds then started to hit on all 4...Ran like normal for about 1 minute and then spurttered and died just like the other day...Now will not hit at all...

Here is what I did today:

1) Rechecked timing marks...Dead on...
2) Pulled dist.cap and verified rotor was in fact at plug wire for cyl #1 while at TDC. It was.
3) Rechecked for fire at each plug.. Got fire....
4) Replaced fuel filter.. Still no start..Not even a hint of starting,
5) Verified that injectors are firing while cranking...They are. Plugs were wet.
6) Pulled plugs to replace....
7) While plugs were out did compression test on each cyl... 150psi + on each Installed new plugs
8) Sprayed starting fluid...Not hint of starting...Maybe bad fuel? Had just filled up just before problem started...Maybe bad fuel diluting starter fluid enough to not fire????
9) Completely drained tank by hot wiring fuel pump directly to battery. Removed FPR and back flushed to filter.
10) Filled with fresh gas...No change..Still no hint of wanting to start.
11) Tried cranking while fuel pump hot wired...(bypassing all relays etc) Still no hint of start.


My plan of attack for tomorrow will be:
1) Recheck for massive vac leak..(booster, idle control circuit etc)
2) Replace rotor and dist cap...Perhaps an internal crack or something is sending spark to plugs but at wrong time?????
3) Pray????

Any other ideas???
