I was changing the spark plug wires on my 1992 ford ranger. one at a time.one wire came.i got mixed up i need to see a picture of the wiring from distributor to engine block

recheck wiring placement probably replaced incorrectly Ford Ranger Bronco II 2 9 liter Engines this link will assist in firing order

Common Sense - tells you that replacing spark
plugs & wires,while they may be an issue, or due
to be replaced,they won't all fail at once & cause
a no start

You need to check for fuel pressure at the motor
with a gauge & check for spark or injector pulse, while
cranking the motor with the starter.

Compression has to be on all cylinders & any timing
belt or chain in place & working correctly

i think this is what you need

cam shaft or timing belt wore out

if you are changing engines you must use everything off the 94 engine

Here's a picture that should help.

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.

Changing the spark plugs is a pretty easy task. The spark plugs run along both sides of the engine (if its a V block) , 1 per cylinder. You can easily identify them by the plug wires running to them from the distributor. Pop off each plug wire, (1 at a time) and replace the spark plug. Once you have replaced the plug, replace the plug wire. This ensures that you dont mess up the sequence of the wires which determines which cylinder fires at what time in the cycle. VERY important not to mess up the sequence. If you should happen to get the wires mixed up, look online for the firing sequence for your vehicle and engine.

DID YOU CHANGE PLUGS ONE AT A TIME ,IF NOT YOU COULD HAVE MIXED UP PLUG LEADS HAVE A LOOK TO SEE IF THIS HAPPEND.
