  1. Yes I remember dropping the tank on my 97 Deville. Not fun, I remembered we all complained about that it would be much simpler to just cut an access hole in the trunk. I guess someone was listening and they did just that for the 2000 body style. Pump came in today with the new pigtail. Now I have to clean the trunk out to get to it.
  2. I made sure I checked the fuel pump fuse and relay before I ordered the pump. I found out today that I can access the fuel pump from the trunk, so that made me feel better. No crawling underneath to drag the tank out and change the pump. I also ordered a Delphi pump from Autozone for $185 after a 20% discount coupon from their website and free shipping. They beat Rockauto and Advance on a Delphi pump which surprised me. I think the reason it wasn’t showing a stumbling code was because the fuel pump was failing. Now my biggest challenge is to empty the trunk to get to it.😳😂 I will post after I install it.
  3. Car won’t start today, checked the fuel pressure and only had 13# pressure. Time for fuel pump?
  4. I checked the codes and it is missing at idle but not throwing any codes. I use Penzoil 5W30. I have not checked the fuel pressure but I have checked the Fuel Pressure Regulator. My Fuel pressure gauge got broken a few years ago and I haven’t replaced it yet. Yes, this is the 2004.
  5. I have replaced spark plugs, front and rear ignition control modules, ISC. Plenum, heater blower, and PCV hose. I think one injector wire or injector is causing the problem. I will have to check around to see if I can find someone with an analyzer. I will check codes today.
  6. Yes. My wife has been driving it all week and I haven't had a chance to run the codes again.
  7. Chasing a slight miss at stops now. No current codes set yet. Gas mileage back up to 21mpg.
  8. I didn’t feel like taking the 94 out. I just bought a new starter and put it in.
  9. I’m sorry I meant to say that the Caddy mechanic replaced the front coil pack module not the front injectors. I’m now suspecting the rear coil pack module. Going to have the caddy mechanic check it out. Thanks.
  10. I replaced the injector seals and applied the grease when reinstalled, but the miss is still there. I talked to my father-in-law and he said a caddy mechanic had replaced the front injectors but not the back, so that is what I am suspecting now.
  11. UPDATE: I finally got time to put a new starter in and all is well. Starts and runs great again. Thanks for all the great advice.
  12. I did not replace the seals or grease them so I will start with that and let everyone know if that fixed it.
  13. I recently had to change the PCV hose that comes out of the intake manifold and goes to the rear valve cover on my father-in-law’s 2003 Deville. In doing so I had to lift up the intake manifold and remove the fuel rail. I had to pull out the injectors when I removed the fuel rail. Put it back together and now I have a P0300 and stumbling at stops. I am suspecting an injector problem. How can I check the injectors? I checked the FPR and it was fine. I cleared the codes and will check them again later.
  14. Thanks Mike, I talked to my Cadillac mechanic friend and he said that if the engine numbers (8th digit of VIN) match the starters should and they do. I am hopefully going to get time to take the one out of the 94 this weekend. My father-in-laws 2003 Cadillac Deville is having vacuum problems again. I am suspecting the rubber elbow at the left side of the intake manifold. I changed the plenum a few years back. I had a problem finding that elbow the last time I changed the one on the 2004 some time ago. I ended up buying a bent rubber line the last time. I will check again but may end up going the same route with the 2003. When I tear into the 94 I will have to see if it has the elbow and kill 2 birds with 1 stone.
  15. Would it be possible to use a 1994 Deville Concours starter in a 2004 Deville? The numbers for an aftermarket starters match but Acdelco numbers don"t.
