I have a 98 Deville (Northstar) that "cranks" quite a bit before starting, after it has been sitting for awhile. However, when it sits all night it starts right up, as well as when sitting for only a


There is a check valve inside the fuel pressure regulator that can leak off the necessary fuel pressure to start the engine quickly. Have it tested or just replace it.

98 Deville had a dead batt. Replaced, turns over but wont start


Sounds like fuel issue, remove the black plastic cadillac cover on the top of the engine, then find the fuel rail on top, and remove the black tire cap looking thing on the end of the fuel rail. Now you will have to get a fuel pressure guage ($45), and screw it on right there. Or you can also just poke that little valve with a ink pen to see if any fuel squirts out, it should come out with alot of force, it is like a valve on a bicycle, it only lets fuel out when you push on the valve ***. As for the battery being dead perhaps you left your parking lights on? My 97 deville, had a cold start problem, that it took 5 minutes of cranking off and on, to get it cold started, but after it was running it would start throughout the day just fine. I ended up replacing the fuel pump in the tank, and the fuel filter on the rail.

97 lumina, 3.1. Starts runs smooth, drive for 30


I just recently have been fighting the same problem with the same make/model/year vehicle. For myself, I would drive off and on through the day and it would run fine. Then suddenly after a start it would run rough and die. I would have to wait 20 to 60 mins before it would start again. I had it checked and fuel pump was only putting out around 19 psi. It should be around 41 psi. Had fuel pump replaced and no more problems. Furthermore, now it runs so much better. It's funny how over time I didn't notice how the performance was slowly degrading. Unfortunaley fuel pumps for this car run around $300.

My 97 cadillac deville wont start right away it wants to spit and sputer then after a few min it will start then it seems to run fine what is the problem? I turn the key on and the fuel pump runs. I let it...


There are a number of think's that could cause this . wont start right away when ? First start of the day ,anytime ? Testing would have to be done to know for sure . IF it seams to run fine after it does start ,it would be a fuel pump or filter problem . More then like a fuel management system sensor problem . mass air flow sensor comes to mind . But having a qualified repair Tech . looking at scan data on a professional type scan tool Should be the thing to do.
048 Engine Hard to Start or No Start Scan Data for Starting Problems
Plus checking fuel system for bleed off .
