Died after new fuel pump
I have an 86 vette that I put a new fuel pump in. It ran great for the first day. Then while I was driving it started to lose power. It died on me and now it will not restart. Anybody have any ideas what may be wrong?

Fuel pumps fail. Sorry. You need to pull a pressure reading from the fuel rail at the schrader valve. If you have no pressure, you have your answer.

By "restart", do you mean it is cranking but won't catch? If so, check the fuel pressure, spark and injector pulse.

I just posted a new thread because the same thing happened to me, it turned out to be the ignition coil. Was running fine and just stopped and would not restart. I don't know that this issue throws a code though, they found it putting it on a diagnostic machine after I had it towed in.
Good luck, sucks to break down while driving...

OP: Statistics text books, in the chapter(s) on "MTBF" (Mean Time Before Failure), talk about "infant mortality" as being THEE most vulnerable period in a device's lifespan for failure. It happens more often than you might think.
Bill is right. Do a pressure test at the fuel rail and CONFIRM whether the pump is working, or perhaps discover that something else is failing...like the COIL, as suggested. But, do yourself a favor and DON'T just start "changing stuff until the problem goes away". Ya ALWAYS, ALWAYS should verify a failure if possible. Otherwise, by flooding the problem with assorted new parts, your chances for "infant morality" doubles and triples with the addition of new parts, and that's a FACT.
Good luck. Let us know what happens.

No, in my case, I meant that the car died while I was driving it. I had not changed the fuel pump. When it happened, my initial thought was it could be the fuel pump because it would crank but not start. Turned out to be the ignition coil.

Same thing that the OP is talking about didn't happen to you
