If the lights are switched then the switch controls a rely all lights are switched on bmw. Can use fog lights temporarily. Find rely test with continuity meter when on, disconnect lights first, then turn on lights switch, check for 12v at light bulb terms, if 12v then bulbs bad, if not relay is bad, test with continuity meter, rely should read 0 ohms when lights switched on, infinite open circuit when switched off. If lights work in manual switch pos then solar sensor bad.
It could be a bunch of things I would check the fuel pump relay first its located inside the glove box behind a panal that says relays its the one on the far left . The way the fuel system on this vehicle works is the fuel pump will still work if the relay is bad because the system it backed up through the oil pressure sending unit. That is what actualy sends the voltage to the fuel pump however the sending unit has a switch inside of it that needs the oil pressure to be high enough to trip the switch to send this voltage to the fuel pump. On a cold day the oil pressure can't build high enough to trip this switch so you get no fuel this it why they tell you to put 5 30 wight oil in the engine. This isn't the olny possible answer to your problem however its what i would look at first and if your running 10 30 i would also replace the oil pressure sending unit. Im assumeing that the vehicle is cranking but not starting from what you have said ?but let me know i know how this vehicle works
The fuse to check is the 30 amp injection fuse. It's next to the battery as shown below. you can interrogate the relay socket or check for voltage at the fuel pump connector. The latter is the surest way to know if it's the pump versus the circuit. The green and black wires at the fuel pump connector are the ones that run the pump. Not sure where the relays are, but I see 3 along the firewall in the pic below--hopefully they are labeled. To interrogate a relay socket, see my post at http://www.fixya.com/cars/r6022358-relay_check .
The fuel pump reset switch on your vehicle is located in a small compartment on the left side of the luggage compartment.
On your 97 Blazer
The fuel PUmp RELAY is located in Right side of dash
Behind the glove BOX.
You can identicate for the colour of the wires.
2- Dark green/white
NOTE... Check the oil pressure switch, because the GRAY wire pass throught the OIL pressure switch.
OK... I hope this help on your problem..
Thank you for use fixya..
