Timing belt all set and adjusted and it's all spot on and lined up, but the car still won't run. It fires, then sputters, then dies.
Fuel pressure is 60 psi.
I did a compression test and here's the results (dry psi / 1 spoon of oil psi):
#1 - 170 / NA
#2 - 170 / NA
#3 - 60 / 85
#4 - 65 / 100
Is the next step pulling the head?

That fuel pressure is way high. That's like normal fuel pressure at 21 psi of boost.
I reckon it's head pulling time. At the very least you got a blown gasket between 3 and 4.

I've always wanted to do that! Guess I have a plan for tomorrow
There's no water in the oil BTW, but I drove it less than a quarter mile to my driveway after it started noticeably having a problem.

2.3s arent a full sleeve engine, they just blow between the fire rings. very rare to have oil/water mix into the cylinders or into each other due to head gasket failure.
side note, i replaced my HG last winter, from running on 2 cylinders to running on 4 and driving it, in 6 hours. i replaced NOTHING but the gasket. $10, 6 hours, burnouts. i didn't even change the oil (had 1500 miles left on it), and i filtered the old coolant through a t-shirt and dumped it back in.
have fun!

That's almost exactly the readings I had when my head gasket blew. I read somewhere that the TCs have a tendency to blow out the gasket between cylinders 3 and 4. Article didn't say why.
Telltale sign for me (like a slipped or broken timing belt) was the rahhh-rahhh-RAHHH-rahhh-rahhh, rahhh-rahhh-RAHHH-rahhh-rahhh sound of the engine cranking--it wasn't the rhythmic sound we're all used to hearing, the continuous evenly-pitched sound. There was a point when it was a much higher note for a second or two, I'm guessing because the mistimed valves/blown gasket was allowing air pressure to escape from the pistons at that point.

I'm slow at this, but I take something off, label it then go do work in hope of getting paid, BUT, now I have 2 questions.
1. FUEL RAIL: after the bolts are out, does the fuel rail just pull off of the injectors?
2. EXHAUST BOLTS: It seems they are 17mm but they have a bit of play in them. The SAE tools I have don't fit and I don't think I want to round off they bolt heads.

1. Yep, the injectors just pull out. Get some fresh O rings when reassembling, 1 each, top and bottom.
2.They are 17mm. That's what I used on them. Soak them for a day or3 with PB Blaster or other good penetrating oil.

Depending on whether the injectors are OEM (or not), there might be some small light blue plastic caps or "hats" (they look like derby hats, like Wimpy from "Popeye" wore). The small opening at the end (top of the "hat") is where the fuel is, uh, injected from. This opening tends to get full of gunk, dirt, gum, etc. You can CAREFULLY pry off the caps with a screwdriver, but work VERY SLOWLY. Underneath the cap is the pintle, a little needle-looking arrangement that's the actual port the fuel comes out of. If it's bent or broken off, the injector is now garbage.
The caps become bent or damaged almost every time that you pry them off. Pep Boys and NAPA are a couple of places you can get replacements, I'm sure there are others. Pep Boys used to sell a kit that had the plastic rings/spacers, o-rings and the caps complete for all four injectors for about $20, if memory serves me correctly.
You might try using a spray carb cleaner to remove all that crap, but I've always just replaced the caps, o-rings and spacers on each. They're not expensive and I think it's a better repair.
