98deville Posted August 19, 2008 Report Share Posted August 19, 2008 How hard is it to get to the starter on a 98 deville? I know taking off the intake manifold is involved, just wanted to know if there's alot of stuff you have to take off to pull it off.... Link to comment Share on other sites More sharing options...
lothos Posted August 20, 2008 Report Share Posted August 20, 2008 We just had a post about a 1995 starter. Your 1998 will probably have different steps and torque settings, but this should give you an idea of what's involved: http://caddyinfo.ipbhost.com/index.php?showtopic=18650 WARNING: I'm a total car newbie, don't be surprised if I ask a stupid question!

98deville Posted August 20, 2008 Author Report Share Posted August 20, 2008 Should I replace all injectors once I got all that off ...My car has 112K There's also a little engine oil going inside where the spark plugs go. what else should i change as a tune up Link to comment Share on other sites More sharing options...
lothos Posted August 20, 2008 Report Share Posted August 20, 2008 Should I replace all injectors once I got all that off ...My car has 112K There's also a little engine oil going inside where the spark plugs go. what else should i change as a tune up I wouldn't replace the injectors unless one is leaking or not working right, but that's just me. I'll let someone else chime in on this. I believe that a little engine oil in the spark plugs is fairly common. Like a teaspoon amount, I believe. Unless it's a lot, don't worry too much about it. Clean it out when you change the plugs though. For a tune up, change the air filter. I changed the fuel filter on mine as well. You're probably due for new plugs and wires. Stick with ACDelco, most people on here would recommend them and other brands can aparantely cause misfires. I found them for a good price at www.rockauto.com and there's a discount code you can use for 5% off, click the little link in my signature at the bottom of this message. You could also think about changing the oxygen sensors. WARNING: I'm a total car newbie, don't be surprised if I ask a stupid question! Just trying to learn.

KHE Posted August 20, 2008 Report Share Posted August 20, 2008 If the wires are not arcing, they are fine. Check the plugs and if any of them are missing the platinum pad on the ground electrode, replace them with the AC Delco dual platinum (OEM) plugs. Do not use ANY anti-sieze on the threads or any silicone grease on the wire boots. It is very important to use a torque wrench to torque the plugs to the factory spec. when installing the plugs. Beyond the 100,000 mile interval plugs, there is nothing to "tune-up" on these engines.

You could replace the O-Rings, get an o-ring set. DO NOT ATTEMPT to clean the TIPS!!! Oil in the spark plug wells, is due to bad CAM cover seals (spark plug port seals). You might try torqing the CAM covers to spec, DO NOT over tighten, go to spec. When was your FPR changed?

Took everything off and wiped off the tips on the injectors...The FPR was changed, about 1 or 2 yrs ago. Changed the spark plugs and wires about a year ago . About the starter, took it off and got it tested at Orielly's- the starter was good. Just recently replaced the alternator 2 months ago with an ac delco reman. Could it be the battery?

Does it turn over and not start? Does it turn over at all? Is starting intermittent? Link to comment Share on other sites More sharing options...
BodybyFisher Posted August 21, 2008 Report Share Posted August 21, 2008 As Jim noted, you just said how do I change the starter. What are your symptoms, that was never made clear. IF when you start it up, you have P030x misfire codes, its because in touching the injectors you clogged them, you will need to replace the clogged injectors, they are about $75 each Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
lothos Posted August 21, 2008 Report Share Posted August 21, 2008 Try cleaning the battery terminals until they shine. The positive terminal comes apart in a couple segments, one of which goes to the starter. I think you can pull the plastic off and clean under there as well. There's a couple grounds that can be cleaned as well. That's the recommended first step that I've seen on here when dealing with electrical issues.

98deville Posted August 23, 2008 Author Report Share Posted August 23, 2008 It turns slowly and as it turns, it's draining the battery and it also pops the trunk and fuel door open when I turn the key back. I also hear a popping noise through the speakers....The car was doing this for awile, turning slow but would start and now it just drained the battery...Could it be a short somewhere in the car Link to comment Share on other sites More sharing options...

The trunk popping open and the fuel door popping open points to a bad battery unless you are grinding on the starter for a LONG TIME. Have the battery LOAD TESTED to make sure there is not a problem with the battery itself. A bad battery may be your only problem. Link to comment Share on other sites More sharing options...

98deville Posted August 24, 2008 Author Report Share Posted August 24, 2008 put everything back with battery fully charged car still wouldnt start so I put some cables on, finally the car started. The volts stay ay 12.6 while car on then go back down to 12.0 - 11.8 while off I also got a PCM P0507 code Link to comment Share on other sites More sharing options...
Texas Jim Posted August 24, 2008 Report Share Posted August 24, 2008 put everything back with battery fully charged car still wouldnt start so I put some cables on, finally the car started. The volts stay ay 12.6 while car on then go back down to 12.0 - 11.8 while off I also got a PCM P0507 code I may be mistaken, but I think the volts should be higher than that when the engine is running. Maybe between 13.5 and 14 volts. Have you had the alternator output checked? Does it turn over real slow even when you have jumper cables on it or does it turn over at normal speed and just won't start? Those are two different problems. Slow crank speed... hard start. Normal crank speed... hard start. I think the P0507 code is related to the Idle Air Control. Check all the vacumn hoses for leaks, loose connections and broken hoses or connectors. Also check the wiring to the MAF and make sure it is plugged in. Link to comment Share on other sites More sharing options...
BodybyFisher Posted August 24, 2008 Report Share Posted August 24, 2008 Check the resistance of the battery cables, you could have a bad cable that has melted or oxidized causing high resistance. That is assuming that the battery load tests ok. Voltage means nothing, batteries die under load, it will have 12 volts until the key is turned then 8 or 9 volts. You had it load tested?

KHE Posted August 24, 2008 Report Share Posted August 24, 2008 Now we're getting somewhere... the car wouldn't start until you jumped it. Have the alternator checked for the proper output. If the output it is too low, have it rebuilt by a local rebuilder. It will last much, much longer vs. a POS chain store alternator.

98deville Posted August 25, 2008 Author Report Share Posted August 25, 2008 Just replaced the alternator last month with an ACDELCO. Yea with the battery fullly charged it still wouldn't turn on till I put some cables to it then it started right up...took off the cables then turned off the car to see if it would turn on and it did with no slow start, been turning on since last night and all day today with no problem Link to comment Share on other sites More sharing options...
KHE Posted August 25, 2008 Report Share Posted August 25, 2008 Most of the auto parts stores like O'Rileys, Advance, Idiot Zone, etc. have a machine that can test the alternator output while it is still in the car. It might not be a bad idea to have the alternator tested if only to rule it out. It still sounds like there is some corrosion between the positive battery cables at the battery. Did you clean all the cables where they connect together? Kevin '93 Fleetwood Brougham '05 Deville '04 Deville 2013 Silverado Z71 Link to comment Share on other sites More sharing options...
98deville Posted August 25, 2008 Author Report Share Posted August 25, 2008 I didnt see any corrosion where the wires connect to the battery but I did see alot of corrosion on the wire threads themselves when I peeled back the plastic covering on the positive wires Link to comment Share on other sites More sharing options...

Ed Hall Posted August 25, 2008 Report Share Posted August 25, 2008 You might want to take apart the alternator pigtail and look for melted wires. Remove the conduit and tape about a foot away from the alternator. Someone had similar symptoms to yours and ended up replacing 3 alternators before discovering the melted wires.

By 98, they may have done away with the sandwiched cables though. Kevin '93 Fleetwood Brougham '05 Deville '04 Deville 2013 Silverado Z71 Link to comment Share on other sites More sharing options...
