Ok I’ll have to a gauge then and pull codes tomorrow evening. Thanks

Ok thanks was no sign of any gasoline in vacuum hose but didn’t quite get regulator seated properly first time so fuel squirting everywhere so gotta a back out for little bit. Getting plenty fuel there. Gonna give little bit to air out then I’ll go check out codes. Thanks

Ok gentlemen, replaced fuel pressure regulator and still doing same thing. Tried to pull codes but really don’t know what kind of code looking for IPC, PCM, etc ?????

Not every time at first but last 4 times started it did. Didn’t try it tonight but wouldn’t start last time tried yesterday morning

Not losing any coolant, already took heads off and replace bolts with oversized studs. Check engine light is on but havnt had time to pull codes yet. 12 hr midnights makes time limited. Just trying to get some idea where to start when I do get some time off. It only started this after sitting for few days in cold weather ????

Hello all, Ive got 1999 Devile recently started giving me trouble on start up. Turns over great but if it starts it is really rough for maybe 15 to 20 seconds. Sometimes when it does start maybe for about 5 seconds it runs really rough until sounds like small backfire through throttle body. Thinking might be throttle position sensor ???? Runs great whenever it does start with no hesitations at all. Any ideas would be appreciated !!!!!

Thanks for the information !!!! This website is the best !!!!

Sorry !! 1999 Deville 4.6l.
