I'd suggest doing a leak-off test on your injectors before buying newer ones, there's a guide in the link in my signature. If you can get the car on a proper diag rig that would be better, live data makes it a lot easier to see what's happening. Try swapping out the lp pump for a known-good item, just to test it. Where are you based? May be members nearby who can help with diags or parts to swap.
