How do you use a jumper wire to obtain codes in 95 contour

There is probably a way to access codes by using a jumper and causing the engine checklight or an integral led to flash in groups. I can't say which pin or pins need jumping.

I suggest you ask the question of google and click on the youtube video.

check the spark plugs and wires and also check for vacuum leaks

I'd suggest getting a chilton or Haynes book for your car first. Very handy! If no spark, you can test the coil with an ohmmeter, and test wires to it. Another possibility is wires to crankshaft position sensor shorted, or sensor is bad. This sensor tells computer when to fire, and if bad, you get no spark situation. Also check any fuses that have to do with ignition.

DTC P0332 is for a knock sensor, not egr valve. That's not to say one of the multiple codes you've mentioned wasn't for the egr valve.

What are some of the characteristics the vehicle is showing. By the way, what is the vehicle? In one place it says 1995 contour, in another it says 1995 explorer.

TPS sensor
Fuel pump relay
a new fuel filter if the old one is plugged up solid
Computer
By chance did you check the computer for any fault codes? If any stored it will tell you what the problem maybe

Does it plug in? I would not worry about wire colors. Why are you replacing the switch?

CHECK THE COOLING FAN CIRCUIT WIRING , CHECK EACH WIRE FOR CONTINUITY , AND ENSURE ALL CONNECTIONS ARE CLEAN AND FREE OF CORROSION.

IF YOU GO TO YOUR LOCAL CAR SHOP (AUTO ZONE FOR EXAMPLE) AND GET A HAINES REPAIR MANUAL ON THE CAR. THE BOOK DOESN'T COST MUCH AND WILL GIVE IN DEPTH INSTRUCTIONS WITH PICTURES

you have a obd2 it has 16 data link connector you have to use scanner to get codes.now the obd1 system have 12 data link connectors..the top two at far right is where you put jumper wire to retrieve code.
