If you can crank the engine, VATS isn't your problem. VATS measures the resistance of the pellet in the igntion key and if it isn't within 5% of correct, the start enable relay won't be closed (and the starter won't crank the engine) and the fuel injectors will not be pulsed by the ECM.

Dittos, buy some starting fluid, spray into the throttle body. If it starts temporarily, its the fuel, injectors,ecm...they aint opening or theres no fuel behind them. You will solve alot of issues by doing this simple test especially wondering if the spark side is working, timing, coil, module,wires... and so on.. carry on ..

It appears he isn't listening, guys.

tried the starting fluid a while back and no results. maybe didnt spray enough in. CFI-EFI are you saying I'm not listening or one of the respondents? Sorry if some of the questions seem redundant.

David:
!. Squirt or throw about 1 teaspoon of gas into the plenum with the butterfly valves open and attempt to start the car (two members have suggested this to you). I think you will fine it will start as there is a good chance you are not getting fuel to the cylinders. It will run for a few seconds and die. You will then need to determine why you are not getting fuel.
2. You did not state (inform the forum members) how the fuel tank became filled with water. If this water got into the injectors, fuel pressure regulator, etc......you will have starting problems!

The water got into tank by sitting outside for a year and the of drain hose clogging. I thought this would be understood since it is such a common scenario.
I guess that was one of my questions if I am getting good pressure at schrader valve could it be a bad regulator? and pressure holds steady as a rock at least 40psi. Injectors have normal resistance and voltage going to them. I did put gas and starting fluid in air horn and not even a "lick."
Thanks for everyones input.

David: You are not getting ignition at the proper time during the compression stroke.....if you are getting a spark and you placed gasoline in the plenum and did not get a "pop or run" condition. Have someone sit in the car and you have them "bump" the starter until the TDC line on the vibration damper lines up with the TDC mark on the engine pointer. When you get this condition either #1 or #6 cylinder is in the compression stroke at TDC....and you do now know which it is!
Remove the distributor cap and see if the rotor is pointing at either the #1 or #6 plug wire. If not, your wires have been moved. Make sure your wires are located in the following order: 1,8,4,3,6,5,7,and 2 in a clockwise direction as viewed from the top of the motor. On my 89, the #1 wire is locaated in the front center of the distributor slightly rotated to the passenger side. If you need a photo of my distributor wiring, let me know!
