The car is a 1986 conv. If I wait a period of time before cycling the key the pump starts all of the time. If I cycle quickly it sometimes does not.
When I turn off the key I hear beep, beep, beep. Not real loud. The car has not run for sometime so I don't think it was in closed loop.
Thanks

If I wait a period of time in turning the key on and off the pump runs. If I cycle quickly the pump does not run all the time. The car is a 1986 conv. I do not think it was in closed loop because the car has not run for sometime.
When I turn the key off I hear beep, beep, beep. The beeps are not loud.

Right now the sending unit is out of tank, but hooked up to check if pump runs. When this whole thing started,I had no fuel pressure. I only hear the beeps when the key is turned to the off position. 3 short beeps, not very loud. I am trying to figure out why the pump runs all the time if there is a delay before I turn key on again. If I cycle quickly then the pump does not run all the time. Then if I wait then turn on the pump does run for the 2 sec. I still have to put everything back together before I can see if car will start.

make sure the line from the pump is on good and pressure test it.

It depends on whether or not the ECM was in closed loop mode when the ignition was shut off. If it was in closed loop mode you must wait 11.3 seconds for the ECM to do an IAC reset and MAF burnoff (on '80s cars with MAFs). That shouldn't be a problem in your case and I believe that you can cycle the ignition as quickly as you want.
I don't know about beeps. I don't recall hearing any beeps on my '86 at shutdown.
I shut off the radio and turn off the HVAC so I can hear the fuel pump run. I usually open the rear hatch also.

I used Seafoam (brand name) in my '88 (available at most auto parts stores).
Initially I had inadequate fuel pressure (10#),
After replacing the fuel pump and getting plenty of fuel pressure (40#)... she acted like the fuel injectors were clogged... and wouldn't run reliably.
I figured my next step was to pull the fuel injectors and clean or replace them..
Based on what I read on this forum, I figured I'd give the SeaFoam a try.
I did NOT suck
the SeaFoam thru the vacuum lines... 1) that would have defeated the purpose of cleaning the injectors.
2)The car didn't run good enough to try that,
3) I wasn't trying to clean carbon in the cylinders
and
4) I don't like the idea of a "non-compressible" fluid in the cylinders.
I put (the SeaFoam) in the gas tank, (just like any other fuel injector cleaner).
Once she started (somewhat) I rigged the throttle linkage to keep her @ 2000 RPM, let her run for about 45 minutes....
Worked like a champ...

While I was removing the fuel filter I noticed a leak in the return line. Is there a lot of pressure in that line? Can I splice in a section of rubber fuel line, or does it have to be metal.
Thanks

I first want to thank everyone for their help with my no start problem. The car is now running, with a new pump and pump relay.
I now have another problem. Every time I open the door to start the car the alarm goes off, and I have to wait till it times out. It is going off even with the car running. Also when I turn the car off and get out and close the door the alarm goes off. Can I disable the vats. Thanks Rich..

Your situation seems to be either with the factory TDS OR maybe the alarm system that I asked about earlier isn't actually removed/defeated BUT it certainly isn't a VATS issue.

Maybe just rotating the door key back and forth in the cylinder and making sure you remove the key in the vertical "straight up/down" position. You might also check the door jamb switches for a situation.
