93 Astro Van fuel pump situation. Electrical?

93 Astro Van fuel pump situation. I replaced the 2 relays on fire wall ( why two i dont know. Manuals all say only one). no buzz from fuel pump. Then jumpered power to the test circuit and got a buzz and engine sputtered but wouldnt start ( residual pressure in fuel line maybe).

Can I bypass the line from the relay and connect the test circuit to the relay,and have it work safely?

It all depends on if the wire does or doesnt have power when u shut the key off, if it does the pump will run non stop even with the key out,i would suggest getting the relay working properly,also depending how u hook it up u dont want too much voltage runnin through the relay...u could melt it,hope this helps

No power to fuel pump 1986 astro van


there is a green single wire under the hood on the fire wall that is taped in the wiring loom. this is a direct feed wire to the fuel pump. if you jump power to this wire pigtail the pump should run. if not then it could be a bad fuel pump or wire connection at the pump. if it does work then it could be a pump relay under the hood that has an open. while checking power also check ground circuit as well.

Chevy astro van turns over but wont start when


Check to see if the fuel pump is kicking in,
when you turn the key on without starting the van you should hear it kick on for about 2 seconds,

It could be...
A clogged fuel filter...
Blown fuse for the pump..or bad pump relay..
No gas
Bad fuel pump

93 astro van turns over has juice but wont fire


a real quick way to test your fuel pump is to take a rubber mallet and have some one crank the engine while you beat on the bottom of the gas tank if your vehicle starts you have a bad fuel pump and it should be removed and replaced with a new one,
