I scratched the opening to equalize it but as I watched it the same day as the battery which is now disconnected while waiting for the new one, I have to wait ...

I would not fail to tell you what I fiddled with if it works ...

If all that does not work, I will have to dismantle the new ACDELCO pump to try the DELPHI that I have in stock And I don't really want to.

I noticed that on many posts, the guys who ask for help rarely say how they finally fixed ... the French are the same!

Swing 4 the fence loosely translates.
Hazard a guess..
Grabbing at straws..
If all else fails..
Etc., etc.

My 97 jimmy 4x4. I also replaced fuel pump, hoses and relocated fuel evap system with new fuel lines to new spider, had to replace gas cap too.

When you changed the pump, was it the entire assembly? Or just the pump? There is a tube from pump that can crack and loose cyphen.

The gas tank is normally vented to the atmosphere through the normally open vent solenoid so the gas cap doesnt matter during normal operation. When you have a bad gas cap it causes the evap system to fail the routine ECM test when it closes the vent solenoid temporarily along with the normally closed purge solenoid and then you get a code.

It was a complete module assembly. but I have not checked that everything is connected properly.
If the battery return doesn't fix anything, I should take the tank apart and see this.

It's a Dodge Not a GMC Jimmy? Très belle voiture.

Thanks Georges. I think that the path of the air leak is no longer to follow. I'm moving towards the lack of electrical power of the pump ... we'll see!

What matters is consistent and proper net voltage to the pump. This means that the positive line must be clean right at the pump and the ground must be good. The pump sees the net voltage between the power and ground wires so a bad ground connection can reduce the net voltage.

You just keep on dreaming, your restoration work is really nice. You have to have vision and patience for that level of transformation.
