I had the high-pressure pump psi tested once I got the relay fixed and it was at 60 PSI I don't know if there's a big difference between the years, I think you need at least the 43 PSI.
I don't know if this helps you or not I just wanted you to know that the pressures are pretty high in the fuel pump.

Thanks for the reply. My manual says fuel pressure must be 30psi minimum at key up. I've read elsewhere that at idle the psi should be around 12psi. A lot of conflicting info, I think the best option is to try the higher rates of the two and see if it burns out. If it does that means too much in line pressure leading to overheating condition.

Also, do you know which of the relays controls the pump? After I disconnected the HP fuel pump and removed it, I replaced the blowing fuse and turned the key. Low pressure pump primed and starting spitting fuel all over. So I would assume the pump was definitely frozen, or the plug went bad. Either way I just about destroyed it removing it - thing was really really really in there. Thanks again for the info and anymore suggestions please chime in.
