2004 Deville will not start.


Recommended Posts

I spoke to my local Caddy mechanic last night and it is not uncommon for this to happen. He suggested shaving off the pump or opening. He said that the old plastic gets saturated with gasoline and swells causing the problem. I’m going to try to shave a little off the pump this evening and report back.

Well the new pump is in. I still have to splice the new plug in. I ended up shaving off around the opening to get the old pump out, being careful not to allow the shavings to go in the tank. There’s too much gas smell right now where I spilled gas taking the old pump out so I’m going to let it air out tonight and finish tomorrow. It’s all down hill from here.

I have been watching your progress via email, what a job, wow, that job was rough..   

Glad you got it done.  This is a great thread to show difficulties that can happen.

I have been recuperating from surgery and rehabbing my hip (two separate issues).  Been under the weather
