968 No Start

[WHIGGINS]

This seems like a friendly place, so I am reaching out about my problem.

I'll tell this in as few words as possible. Lately, the car had been hard-starting, but it started. Eventually, it wouldn't start, and I determined the fuel pump had voltage but would not operate. I replaced the fuel pump, and then it started again. It still didn't run well. I got it out of the garage, parked it for a day, and then it wouldn't start at all. It will usually try to start (fires off a few times), but never catches.

So, here are the things I know:

It has fresh gas (drained the tank when replacing fuel pump)
Tachometer bounces when cranked
Replaced the DME and start relays with those from a running car
Fuel pump fuse is good
I cleaned the MAF and tried to start with it plugged in and not plugged in
The Hall Sensor connector is intact
No error codes are showing using the blink test

Any wisdom on where to look next?
