98 S70 dies after starting

Hello,

I have a 98 S70 non-turbo that always starts fine but, sometimes (but not all the time) die after a few seconds. Seems like a fuel starvation issue or ignition cutoff. No fault codes from OBD II.

After a couple of restarts it will run perfectly until the next day. So, the issue comes and goes.

I have replaced the neutral safety switch, checked all the vacuum lines, mass flow sensor, etc. Nothing seems out of place or broken.

Now I'm thinking of replacing the fuel pump relay.

Any ideas would be greatly appreciated.

Thanks,
Steve

Does it only do it when the car is cold? Does it run rough with the car is cold just after start?
