Changed spider injection and feed and return fuel lines inside plenum
The lines are different sizes and if you did... it would dead-head the pump and not start!

Sounds like a bad fuel pump. If you turn the key on and don't hear it run, it is the most likely cause. You may be able to smack the tank and get it working again, but will need to be replaced. If not, look for power and ground at the pump connector when key is on.

check for dryrotted vaccumm lines or off completely ensure all the fuses are good and make sure you have spark by testing it if you need assistance for this send me a reply back sounds as if the fuel is not getting through at this point
SOURCE: Have installed new fuel pump and gas lines in 1995
pull line off of front of filter and cycle key 2 on position if there is no fuel present your feul pump may b the problem, before replacing old one make sure the fuse is good

you can manually actuate the relay if you want. Take the cover off, and push the contact over with a screwdriver and see if you can hear the pump. Have you checked to see if there's power to the relay, both the control side and the side providing power to the pump? There's two different circuits involved here, so you have to make sure they're both ok. If you have power before the relay, and power coming out of the relay headed to to pump, then your problem falls between the relay and the pump. Other things to consider, are the fuel pressure sensor, and oil pressure sensor. Some vehicles will not turn the pump on if they sense no oil pressure after a couple of seconds. Secondly, if the fuel pressure sensor is telling the pump that there's plenty of pressure, (even if there's not) it'll shut the pump down. Hope this helps you.

Check or replace your ICM (ignition control module) The ICM or the Ignition Control Module, is the brains behind the spark plugs. The ICM tells the spark plugs when to fire and lets the engine know when gas needs to be injected for proper engine ignition. Sometimes if your ICM is out or going bad, you may be able to start your motor up nicely once and then when you turn it off it may not start back up. It can also make you feel like your engine shake and "sputter" bad.
Start with the ICM and thank you for using Fixya, good luck
