Re: no feul pressure
It does sound like oil pressure sensor or wire. What kind of PSI are you getting when it cranks? I may be mistaken, but I think 30 is the magic number. You may want to put a multi/ohm meter to the sensor wire. As a follow up for me- I still have not fixed fuel pump on the '89, but I think I will be installing an access panel. I have found a well executed design of such a thing. I can email you a link if interested. Good Luck.
