No-Start Condition & Codes: Newbie's first post

[SHOroom stock 95]

Hey guys,
First-time poster, but I've been searching the archives for a while now. As the name implies, I've got a 100% showroom-stock 95 SHO that I'm trying to sort out. The car had been running fine until it died suddenly on the way to work last week. I could not get it re-started. The car cranks and the tach will fluctuate, but it will not fire. I verified spark at the plugs and can hear the fuel pump prime. Since the car will not run, I ran a KOEO test. Here's the results:

Hard faults:
116 ECT out of range
636 TOT out of range

memory codes:
172 O2 sensor not switching right/rear
176 "" left/front
332 EGR not respond
543 Fuel pump circuit shows no power

Can anybody point me in the right direction based on this info? I would like to verify fuel pressure, but did not see a schrader valve during my quick inspection. Where is the tap-in located? Any help/advice would be appreciated. Thanks.

Welcome!

Unfortunately, none of those codes indicate why a "cranks, but does not fire" is occurring.

The first two codes are likely due to your ambient temp being too cold. Wait until it is over 50 F before attempting to address them.

Neither the O2 sensor codes or the EGR code will account for it. The 543 is often the result of a stall. If the pump is running, obviously the circuit has power.

The Schreader valve is located on the top of the fuel rail and extends upward through the intake's snakes. It should have around 40 psi.

You may need to get a timing light and see if the #1 plug 1 firing and is in time.

Good luck.

Hmm, just a quick test... when cranking it over put your foot to the floor on the gas pedal and see if it starts. Every once in a while my car will do this, and I have to open the TB wide open to get her to start. Could be a leakey fuel injector or something. Another thought, could be your timing belt.

Quick way to check the timing belt is to open up the oil fill cap and look inside. You will clearly see movement of the valvetrain if the timing belt is working. Have a buddy crank her over while you look inside. If you see no motion whatsoever, then the timing belt has snapped.

i have to do that with hime sometimes, when its really cold out, and i come up to a corner, it will stall once in a while from it idling so low (i should fix this) i ususally have to put it to the floor when this happens.
