I just picked up a 1989 F150 to restore and use. The previous owner couldn't seem to make it run anymore. It did run sort of but very poorly and no power. I found the wrong EEC in it and the HP fuel pump "hot wired". I replaced the EEC with a correct reman one and reconnected all the pump wiring. Now a get a code 87 on the scanner. I have found that it seems that the EEC is not grounding the relay circuit. What I need to find is someone or some site that will tell me what the computer is looking for on the "key on" before grounding the FP relay to let the HP pump get power. Anyone have any ideas or help? The only thing I can think of is maybe the fuel pressure regualtor? Seems that when they tell you what the code means they would also tell you how and what to check to fix it. LOL

Any help would really be appreciated

Thanks,
