Help!
Hi. I put a new starter on my 87 f150 and it wouldn't start. The starter is fine but I can hear the fuel pumps running non stop. So I replaced the pressure regulator and vacuum line. No help any ideas?

Hi. I took out the computer and turned the switch on and neither fuel pump seems to be turning on. If it's just the filter I'll be so mad at myself lol.

I’m not sure if I understand correctly, you turned the key to RUN with the computer unplugged and the fuel pumps don’t turn on? That is normal.

ok I didn't see anything burnt in the computer but the pumps both run non stop with the computer in and it's not getting fuel to the plugs. I've replaced the pressure regulator and vacuum hose to it.

The number one symptom of a bad computer is the fuel pump(s) turn on and stay on when cycling the key from the Off to Run position. A few of these pesky computers show no obvious sign of being bad physically, it's inside the magic place where the smoke is still inside with no place to go.

Maybe one of you can tell me, if the pumps are running why isn't gas getting to the firing chamber? The truck was running great before I replaced the starter and fuel pressure regulator

i noticed a sensor beside the fuel pressure regulator, could that be an issue? What about a fusible link?

No idea what you are talking about but no sensor will cause your continuously running fuel pump with the key in the Run position issue.
If a fuse was open then a circuit is open. An open circuit will not cause your issue.
