1995 Ford Explorer Repair Question
What would cause the spark plugs not to fire up?
95 ford explorer
the car turns over but it won't start. I have a full tank of gas and the battery is good. Seem like it getting fuel but it just doesn't fire up. Tested both power plugs that connect to the coil packs and both are receiving power, but when I tested the coil packs they didn't have any power or creating any spark.
I connected a Data Link Reader(OBD II) to the car and pressed the read button & it said "no codes"
Then I disconnected the plug that connects to the the coil packs. Then when I pressed the read button it still said "no codes"
I plugged the ODB II to a different car & it read the codes for that car, so I know my OBD II is working?
SCANNER DOES NOT "DO IT ALL" MAINLY COMPUTER CONTROLLED SENSORS THAT THE COMPUTER CAN MONITOR IS WHAT IT CAN DO
THIS IS A POSSIBILITY---IT MAY CAN BE TESTED, BEFORE YOU SPEND THE $$$
AT THE BOTTOM IS A PIC OF THE TESTER AT ADVANCE AUTO, THERE ARE MANY PIGTAILS FOR DIFFERENT MODULES....I LAID OUT THE ONES FOR JEEP CJs IN THIS PIC. I HAVE NOT SEEN ONE LIKE SHOWN IN MY LINK BEING TESTED....I JUST DON'T KNOW IF IT CAN BE FOR SURE
THERE ARE MANY OTHER POSSIBILITIES THAT COULD CAUSE THIS PROBLEM
THE VERY 1ST EZ THING TO CHECK IS ALL OF YOUR FUSES---OWNERS MANUAL MAY GIVE YOU LOCATIONS AND EXPLANATIONS TO EACH
WIRE MELTED ON EXHAUST?
YET ANOTHER POSSIBLE PROBLEM
THIS STUFF IS EXPENSIVE, SO DO ALL THE TROUBLESHOOTING YOU CAN
GOT A REPAIR MANUAL?....IT'LL HAVE THAT SECTION IN IT, AND "HOW TOs"
LAST BUT NOT LEAST, I MAY BE ABLE TO AID YOU IN CUTTING YOUR COSTS ON SOME OF THIS STUFF, IF YOU DO NEED IT!
THIS INFO MAY BE USEFUL IN THE FUTURE FOR MORE AUTO STUFF AND OTHER STUFF TOO!.....IT IS OVERLOOKED SO OFTEN

I would look to make sure the crank angle sensor is sending signal to the coil packs first .
Then go to the coil pack and or ignition modual(s)
If your car has the 4.6 liter with the plastic intake.
Keep close watch on loosing coolant.
Those intakes crack many times from the water ports over to the air passages and will hydro lock the motor.
If a large amount of water gets on top of the piston, the crank wont be able to turn over , and you will have to pull a spark plug to blow the water out then replace the intake.
