I have a 98 SLS. On Saturday the wife told me she had to crank the starter for about 10 seconds and step on the gas peddle to get the car to start. I went out and tried it, sure enough had to do the same thing. It had the original battery and I thought maybe it was going bad so I replaced it but still have the same problem. Any ideas?? Bad Fuel Pressure Regulator?? Once it starts it runs fine no problems and no codes thrown either.
