Squirrels.
They ate up the wires on my 95. They cut the throttle position sensor wires and the four wire sensor under the throttle (IAT?) I think.
I have replaced the pigtails but it won't start. I'm sure the wiring is correct.
It cranks but it won't start. Fuel pump runs.
Could it be the VATs? Would cutting wires trigger the VAT?

Check for engine codes. TPS codes for the no-start, and a VATS problem will set a Code 46.
Check the voltage at the dk blu wire at the TPS with the key on. It should be ~.5V. A bad connection at the ground pin for the TPS will send TPS to 4.5 Volt which is "Full Throttle" and the ECM will enter "clear flood mode" while cranking. The fuel injectors are disabled in Clear Flood Mode. So even if the wiring is correct, just a bad connection at the ground pin can cause a no-start. Ask me how I know about this one....

I would back probe the connector for the TPS with a meter on the dark blue wire. Should be 0.6 at closed throttle.If it cranks , then it's not VATS. The 4 wire connector is for the IAC.
First check for spark and go from there.
Just on principal check the fuses for the PCM, coil and injectors.
You can unplug the IAC and it should still try to start and probably run.
Check the wires for the opti since they are so close to where the damage was. If a opti wire was cut, it could definitely cause the engine not to start. It would kill spark and injector pulses. Make sure it's still plugged in all the way.

Thanks Jim, Colt, Dogs,
They only chomped on those two sensors. Didn't get the Opti, coil, ign mod. They did break the big clip on top of the computer. Connector is just pushed in but seems good. I will troubleshoot using those methods tomorrow.
Thanks for your help.

Fuel pump working. New.
The ignition is working.
I get .9V at the blue wire.
Fuses at passenger door and next to battery are good.
Opti is pugged in withwires intact.
I've tried to start it with IAT disconnected.
Where else are there critical wires?
I'm missing something.
Thanks.

It is indicating a code. I thought it wasn't because I disconnected the battery.
It is the H12 code. I know this is the distributor. It is firing but it must not be fueling.
The distributor and water pump were replaced this past summer.
There is antifreeze under the engine. It has 50/50 antifreeze. IDK. Still working.

I just checked the antifreeze. It's good for 20 below. It didn't freeze. It not much. It's always leaking something.
I felt under distributor and it was dry.
I'm going to re re re re re check the wires to Opti.

The engine has spark.
Noid light not flashing.
H12 code.
Fuses are good.
I can't believe that Optigrab is bad with less than 1000 miles on it. (Advance Auto Parts). Lifetime warranty PITA to fix.
Any more ideas?

Plugs are firing.
NOID light flashes.
But I won't start.
Could it still be stuck in the clear flood mode ?
I'm stumped.

Even though I put a spark plug connected to a wire on top of the intake and watched it fire it was the coil wire.
I saw where the little bastard bit it but it was only a tiny nick. But it cut the inside of it somehow.
Park you cars inside! They are up my John Deere too. It's war.

Siberian Huskies are great varmint killers I have shoveled the partial remains of possum, coon, squirrel, cats rats, ducks & birds. If you have chickens keep them fenced they like them too. Neighbors ferret escaped the house the Huskies got it.
