2004 Deville will not start.


PAUL T

Recommended Posts

My wife's 2004 Deville will not start. We have been having issues with the starter screeching when it engages before you let go of the switch. Last night it would not start at all. The current codes are as follows: P0102- MAF sensor, P0335 & P0385- Crank sensor codes. The starter was turning over, but the engine was not. No belts were moving. The starter was not engaging the flywheel. I have had MAF problems before, so I will check the plug and possibly change the sensor. Where do I start? I am leaning more toward Crank sensors though. Where are they located? Thanks.

Hi Paul, If the starter is spinning but not engaging its the starter drive.  The starter needs replacing.  I would start there, then tackle the codes.

sure sounds like the starter itself is the no start issue.

Check the main red cable that runs from the battery under the intake to the starter as well.

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.

Paul, I went to rockauto and looked up starters for the 2 years, both new acdelco's and they are different part numbers.  I would sit the 94 next to the 04 starter and match them up.  It might just be a slightly different layout of the solenoid.  Mike

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.

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.

Glad to hear it @PAUL T

Glad to hear.

I assume the 94 was different?

Honestly as rare as they fail I would not put in a used one. A replacement should last a long time

Does the miss go away at highway speeds?

Yes. My wife has been driving it all week and I haven't had a chance to run the codes again.

 

Has any engine work been done?

Do you have an engine analyzer that can provide real time misfire counts?  I am curious what cylinders are misfiring and want to actually see the misfires diminish as the rpm/oil pressure increases.

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.

It would be terrific if we could see your misfire counts at idle, at 2,000 rpm and at highway speeds.  

You have done a lot of work.  

What oil do you use?

I am off on a different direction with your problem but want you to eliminate all causes first.  

Have you checked fuel pressure?

Is this the 2004?

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.

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.

Great. I was going to mention the access. I am jealous as I had to drop the tanks in both of my 97s.

The Delphi should come with the repair pigtail as well. That is what I used

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.

I had to pull tank on my Seville for the fuel pump, The Deville for the fuel gauge(feeler issue). I did both within a week of each other. Not that much fun

Well I having trouble getting the old Fuel pump out of the car. The access in the trunk is great but getting the metal ring off was a battle. It was rusty and wouldn’t budge. After spraying it with WD40 (that’s all I had at the time) and letting it soak a few days it finally came off with a lot of pounding with a hammer and screwdriver. Next I thought the battle was over but the pump will not come out of the hole. I turned it around trying to get it out but it will not come out. I don’t know if I am not holding my mouth right or what, it’s not coming out! I am going to come back to it and try again.

So pump comes up but will not come out of the tank?

it sounds like one of the springs or sender lever is catching on the tank. 

Carefully fiddle it back and forth and it should come out.
