For non-charging issues......check fuse "T" in the engine compartment fuse / relay box.
It is a mini-fuse....and 15 amp.
I've changed that one.......
It will keep a perfectly good battery from charging with a perfectly good alternator. An alternator can blow this fuse when it fails. You put a new alternator in.....and still get no charging action....until you replace this fuse.
For fuel pump.....newer winstars than mine....have issues with the fuel pump relay....which is also in the engine compartment fuse / relay box.
More than a few posts in this forum on the relays in these newer cars failing....and causing no fuel pump operation....and intermittent....very strange symptoms fuel pump operation.
My 1996 has the fuel pump relay, Fan high/low relays, and AC compressor relays in the CCRM (Constant Control Relay Module). The PCM powers the relays..... I have the CCRM replacement information in my pictures at

For my '96, they came out with a new and improved CCRM unit that has better sealed relays.
The problem was...in cold weather...you would drive for a while....long enough to get things nice and warm.....stop and shut off the car for about 15 minutes....and come back....engine cranks, no CEL...but no start....due to fuel pump not running......caused by moisture in the CCRM relay(s).
I have not seen posts in this forum on CCRM issues.....so there must not have been many in the past year.
