Water in the tank, can't get it running again.
 
02 Focus SE 2.0L. This is my friend's car. One day it wouldn't start so she took it to the mechanic. He said the fuel pump was bad, then while replacing it, said he found a couple gallons of water had been dumped in the tank, so the tank and lines were drained and refilled with isoHEET added, the spark plugs were all replaced and the holes blown out with compressed air, but it still won't start. I can get gas to squirt from the valve on the fuel rail, and I tested a spark plug by setting it on metal while cranking and got spark. It really sounds like it wants to start but can't quite get there. Any suggestions? I'm going to try starting fluid in the morning. Her mechanic says he doesn't know what's wrong and wants her to replace the PCM to see if it helps, so I have to step in.

have you checked the fuel cutoff switch just below the glove box on the kick panel? make sure its pushed in.

please check with starting fluid first if the cutoff is fine. if it runs then its still a fuel problem since you have verified spark. if it doesn't run, check the compression.

do not replace the pcm until your diagnosis leads you there

edit: verify that fuel is flowing through the injectors and that havent been seized. im not sure what water will do, if it could plug the screen or seize them.

So, the big hose from the throttle body to the air filter housing wasn't really on tight, it just kinda lifted off, so I sprayed some starting fluid in the throttle body and had my friend try to start the car, and the car just belched a fireball back up out of the throttle body... makes me think there's spark with an intake valve open... I asked a few more questions.
She said she had recently had a new timing belt put on, I asked about the spark plug wires and she's sure they're on in the right order. Is compression testing still my next course, or is there possibly a timing issue, or something else?

Maybe replace the fuel filter while you're at it if it hasn't been done already.

A compression test will give you at least an indication if the timing was done correctly or if the timing belt tensioner has perhaps loosened and the timing belt has jumped.

Cofirming the plug wire sequence should be easy enough; they are marked at the coil "posts" and the cylinders are numbered one to four left to right (facing car) from the crank pulley end.

Is it the same mechanic who wants to replace the PCM that did the timing belt? If so, I would re-do all his previous work. No competent mechanic suggests a PCM replacement "to see if it helps" as mikebontoft has already stated.

X2. Change mechanic. I'd be looking at the timing belt if very recent, that backfire has incorrect timing all over it. The PCM is not the problem. Mechanic is out to lunch.............
