1982 320iA cranks, but will not start....another starting issue thread!

Hello,

I have a US 1982 320iA 1.8l that will crank and not start.

Here's what I know:

Car has fuel, as I filled it up the night before and only drove it less than 30 miles at around 80mph.

I was able to start the car afterwards, however, just around the corner, it sputtered, and bucked a bit, then died.

I took off the gas cap to rule out vapor lock (the car will still not start after a week).

Battery is fully charged.

Fuel pump fuse is good, I even took it out and cleaned it a bit and twisted it while reinstalling it.

Fuel pump relay is good as I took it out and tested it in my 1983 320iS.

Car has plenty of spark!

No fuel spray out of the cold start valve.

I took off the fuel line to the fuel distributor off, and cranked it, and no fuel came out.

I hooked up a 12v battery directly to the fuel pump (while the connections to the car battery were still hooked up) and the fuel pump did not make a sound.

I am pretty confident that it is the fuel pump. I do have the one known fuel pump on my 320iS that I could swap to confirm, however, I do not really want to spend the time at this point.

Is my assumption correct in that it IS the fuel pump? Any guidance is greatly appreciated!!

Regards
