Fuel pump wont fill?

Fuel pump wont fill?

Postby jjjj [OP] » May 11th 2011, 11:34pm

Ok. We have a 94 Astro V6. Recently the van wasn't turning over so we replaced the fuel pump.
Replaced the pump and found that it was not getting any juice to it.

So my father in law ran a wire from the key directly to the fuel pump. Now when turn the key you
can hear the pump running but it doesnt not ever stop. Also the van will still not turn over.

Just wondering what the heck it going on here. I am by no means a mechanic, but have changed correctly
the fuel pump, filter and relay.

Thanks.

be careful working with gas, these systems are high pressure and can prove deadly. So what does this" will not turn over mean". Can you hear the starter turning over the motor and it will not start? If you take some starter fluid and spray it in the engine will it start and run? If you can get one of the spark plugs out is there spark?
Before going all the way with the fuel pump, make sure the battery is strong, spary the starter fluild and post back with the results. We will walk you through every step.

Yes. Please choose your words carefully when you try to describe what is going on. It is hard enough to troubleshoot from afar, let alone try to interpret what some posters are trying to tell us.

We understand that you are not a mechanic, and that is not a problem. Just try to give as much info as you can and be as accurate as you can, within the context of your knowledge. for example:

A. Turned key to Start: starter motor engaged and cranked engine
B. Engine cranked but will not start
C. Checked for spark... Good blue spark from hi tension coil lead
D. Sprayed starting fluid into intake... Engine started, then quit
E. Listened at fuel filler door, while dad turned key from OFF to RUN... Did not hear fuel pump run for the 2 second "prime"
F. Plugged 12v into fuel pump test connection... Heard fuel pump running
G. Replaced fuel pump prime relay... Engine started and kept running.

The above may be a little more advanced than your knowledge base, however, I'm sure that you can easily understand what each step was, and what the logic was.

So, give us something to work with, and we will take you thru the proceedure, explaining what and where things are, and how everything is supposed to work. That way you will have a

better understanding of the system for next time. At any rate, this is how I learned. ( I didn't pop out of mother with wrenches in my hand, Ha)
