Fuel/ign starting problems ________________________________________ I have a 2001 Cadillac Seville sls that has been having intermittent starting problems. Presently the vehicle will not build-up fuel pressure in order to start to 41-47 psi unless I remove the rear fuse/relay box ign 1 micro relay. With this relay removed, I can hear the fuel pump build-up the required psi and then I confirm the build-up of that psi by looking at my test fuel psi gauge under the hood, the car then starts no problem, and runs no problem with relay not installed. Whenever I re-install this micro relay the fuel sys will not build-up the required psi, it just stays at 0 psi, and of course it will not start. I just replaced the fuel pump sending unit assy plus fuel filter today. The other day I was driving on highway 25 southbound and doing 75 mph and the engine just died, quit running and would not re-start. I had my vehicle towed home, the next day I went to troubleshoot my Cadillac and the vehicle started right up with the ign 1 relay removed. As I mentioned earlier I already replaced the fuel pump assy thinking it would fix problem and it did not! today while driving 55 mph the engine suddenly quit running again and I heard a noise from the front end and the car shook also. I had to find some shoulder room, pulled over, removed ign1 relay again and the car re-started no problem and I continued on driving to work.
The consumer's vehicle traction control system keeps showing a defect when the light comes on. The consumer took vehicle to dealer 4 times, and they couldn't find anything. According to owner's manual it has to do with the brake system. . . . The traction control light continues to come on, and dealer was unable to repair or determine the cause. This creates a potential hazard to consumer and others if the light signals a problem. This problem have been going on since October 17, 2004 to the present.
