There is no need for a pre prime feature, it is simply a choice. It can be a band aid for some problems, but I bought it because I like to hear my fuel pump. I went through an entire go round with my car and running issues, intermittent no start and rough running. Having the fuel pump fire up for three seconds tells me something about the health of my relay and the operation of my fuel pump. I like that.

I also have other cars that activate the fuel pump at initial start. I am used to hearing them. As others have stated, no one needs a solid state relay. I wanted one, so I opted for the one with an extra feature. I still carry a known good spare in the glove box. Given the trouble people have had with new, out of the box DME relays over the years, I actively sought out the solid state unit. In the end, I replaced three sensors, a DME, and found two bad wiring connections. Only one of the sensors needed replacing, but it absolutely needed replacing. Finding the bad wiring connection was problematic, simply because it was intermittent, and that made it hard to trace. Now if I have a fuel pump related issue, I do not have to test anything to find out if I am getting fuel. My ear tells me every time I start the car.

To be honest, a good mechanic might have found my issue right away. But being that it was intermittent, it might not have been so easy for him either. I think in the end, even with spending a few bucks extra, it was still cost effective to do the work myself. Plus I made some new friends on this board, and learned a few more things about my car. And you know it feels good when you finally solve a problem. I don't feel good owning a hobby car that I can't fix.

The DME relay was simply a present I bought myself. I also bought a spare here from Pelican.
