upgrade your lp to one that can make at least 9psi of fuel pressure. and hook it back up to ops and do the 10$ relay mod(in faq). your ops may be shot and that's why it was hard wired. only use ac delco for ops.

AC Delco LP from a 93 model is the best stock replacement LP available no matter what year your truck is.
