Download free workshop manual for 2003 ranger extenda cab 2whl drive

Go to Pioneer website and download the manual for your model stereo unit, and wire code will be in manual.

could get to the solution with a more descriptive , make ,model year etc . vehicle,equipment. well i,d say start with fuel. filter, clogged ,pinched or leaky lines . next check ignition, coil, wires, arcing to ground , spark plug. let me know how it goes good luck .

You need 3 things for a cylinder to fire; spark, fuel and compression. You have to check for all 3. The easiest order is the order I stated them.

Same as any vehicle you have ever done

Helper in the drivers seat & you open the bleeders

There are none. The manuals are copyrighted and you must purchase them

You state you changed plugs and wires - Do distributor cap & rotor? If not you should then set timing. That should cure hesitation (might change fuel filter also and run good fuel system cleaner through it)
Prob 2 - sounds like a u-joint or possible brake pad/rotor issue. Does the squeal only happen in mornings when cold? Sometimes after sitting overnight, rotors get condensation and when backing out they'll squeal/grind. Somethings to look at...

Did you replace the wires? if not you may have broken a couple of wires. Not sure what fire wire is unless you mean the spark plug wires. Also did it do this before you replaced the plugs? need to know.

here this help?
