I've been fixing up this wagon that I bought a few months ago little by little. Although it had low mileage (129k) many things had been neglected. After changing plugs wires and cap, amm, cleaning throttle body and some hoses, it was still having a tough time starting. Would crank a while and always eventually start. Well I swapped the fuel pressure regulator with one from my Regina 740 (they are not exactly the same but many sources say that they are interchangeable) and that seemed to fix the problem. I installed a new fpr and I think I'm home free.
