tomcad95 Posted August 12, 2005 Report Share Posted August 12, 2005 My 95 Deville has a problem with starting, when the car is hot (been driven for a while) and I shut the engine off and try to restart it within 10 min or so the car was cranking slow then starting. It has now gotten to the point where the car is not even cranking, no power at all to the starter. All my other accessories work fine. I have take the starter, alternator and battey the the service center and they checked out good. I seen in previous posts where it was advised to run a 4 gauge cable from the negative battey post to one of the starter mounting bolts. Is this going to provide a ground exclusive to the starter or just a general ground, and does the solonoid on the starter have its own ground that might have gone bad?

Run that ground to the mounting bolt first. It will most likely solve the problem. If it does not help, there will be other suggestions, but try it since it is a relatively easy job. Also check the FPR (fuel pressure regulator) for leaks. There is enough information on FPR in archives. Did you try to start hot engine with gas pedal floored (clean flood mode)?

tomcad95 Posted August 13, 2005 Author Report Share Posted August 13, 2005 No I never tried to start the engine with the petal floored when it was hot, but at this point there is no clicking or anything coming from the starter. Would it be better to run a new ground wire from the solenoid terminal or just run it from the battery terminal to the starter bolt, would It be the same result.

I ran a new ground to the engine block next to the starter and it did not help. Then I ran one to the starter mounting bolt (there are two of them with 3/8" diameter) and it helped. There is also a braket which grounds the starter frame to the engine block. Mine was missing...You can try it too or put it to the solenoids negativ. It basicly the same. Make a termination which would by big enough to fit the bolt and move it from one place to other and test. The best test is driving the car for some 40 minutes, letting it sit for 5 - 10 minutes and trying to start. I used the shortest mounting bolt #3 (FSM page 6D2-5) The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...
tomcad95 Posted August 15, 2005 Author Report Share Posted August 15, 2005 Thanks, Im going to try to run a new ground to the starter bolt first, does anyone happen to know what gauge wire is used from the solenoids ground terminal, also on the positive terminal for the solenoid there is the red power wire and there was another wire connected to that terminal, dose anyone know what the other wire is for on the positive solenoid terminal( I think it was green).

KHE Posted August 16, 2005 Report Share Posted August 16, 2005 Have you inspected the battery cable terminals for corrosion? Kevin '93 Fleetwood Brougham '05 Deville '04 Deville 2013 Silverado Z71 Link to comment Share on other sites More sharing options...
tomcad95 Posted August 16, 2005 Author Report Share Posted August 16, 2005 Yes, that was the first thing I checked. Link to comment Share on other sites More sharing options...
awise Posted August 16, 2005 Report Share Posted August 16, 2005 Often times when a starter goes bad it's because the bushings that the shaft rides on are worn and the shaft cocks at a slight angle. That angle results in friction which in turn requires greater voltage (electro-motive force) to turn the shaft. Eventually it gets bad enough that you need way too much voltage to turn the shaft. It gets worse when things get hot. A good way to test for this is to have the starting system voltage checked. You may find that the starter is drawing more power than the battery is capable of providing. Most auto parts stores will do this test for free (with hopes of selling you the parts to fix it). A much simpler source of agravation could be a battery that is not up to snuff. Bottom line; get it tested. Let us know how you make out.

tomcad95 Posted August 16, 2005 Author Report Share Posted August 16, 2005 The starter, battey and alternator were tested and checked good. Link to comment Share on other sites More sharing options...
