Electrical problem
1996 Chevy Beretta 4 cyl Front Wheel Drive Manual 96000 miles

here the problem. all sensor lights are on and wont go off after car is started. also speedometer not functioning. recently replaced ecm, new cooling motor, and fuel pressure regulator. also cooling fan comes on when key in on position and shuts off after car is started and does not come back on even when motor gets hot enough to tell it to. ie will overheat. This was not an issue when car broke down from bad fuel pressure regulator. a coil pack was also replaced. i've checked the engine compartmet for disconnected wire found none. today something diff from yesterday is if i turn the key on and start engine for a couple of seconds, shut it off, the cooling fan will run for about 5 mins. baffled in virginia.
