I've replaced several fuel pumps on these trucks, and the only one I will ever put in is from Dodge.

 

did you check that circuit like i was talking about? check voltage and all at the pump connector? did you check for resistance down the same circuit?

here is the thread i started about the pump issues.

 

I checked for voltage as you described. Only got a small blip on the meter of anything happening.

I had the meter set to 20 Volts Max DC.

Thanks for the reply.

 

small blip? you should be getting 12v at the connector...

 

Agreed. Now the question. What's causing it?

I MAY have not had a good connection because, as always, production line quick connects aren't attachment for testing friendly.

At least it seems that way to me. The wire I used to jump to the meter beside the door (so I could watch...working alone) was a little thick in my opinion. So I'm not sure if it was a socketed contact in the connector.

What I did see consistently is number change when I hit the switch, but only like 1 volt or less. (Didn't write it down.)

I don't know or can't say it's a wiring break or resistance issue yet. More testing tomorrow.

I also read in another forum that the sensor in the distributor will keep the computer/ASD from allowing current to the fuel pump if it is bad or out of range.
Opinions?

Thanks.

 

stand by, modding a wiring diagram a little bit for you

 

ok do this:



that way you are bypassing all the wiring from the battery to the pump. see if that makes any difference and be careful, lol. you can use pin 6 as the ground too. i just drew the ground wire in 4 cuz thats where the pen ended up.

 

Thanks. I'll jump into it again tomorrow and see what I can get going.

A thread drift or note to whom it may concern:

This is the slowest and most difficult Forum I've ever participated in regarding the software or server performance. That's not blame or anything. Just a report. It just turns, and turns, and turns....waiting to post or reload. Pretty sure it is NOT on my end as all other Forums I've encountered using various versions of Vbulletin almost never encounter problems such as this. I can fly on them. It's possible you may have more users or advertisers causing this. Frustrating though.

I do want to note that I am still very appreciative for this Forum though.

Hope that was constructive.

 

Anyone have any ideas as to what the "click" is that I hear consistently?

Thanks.
