What makes you so sure it's wires? Any loose ground related to the cranking system can cause it, faulty spark plug wires will also do it.
There are several reasons why a Crown Victoria will not start. One reason could be a dead battery. Another reason is that the spark plugs and plug wires may need to be changed.
Start with a complete tune up including spark plug wires.
Do you have the wires in the correct order ?
Follow the wires. Have to take off the covers first.
There are a variety of reasons for an engine misfire in a Crown Victoria. You may need to replace the spark plugs and wires. Other causes include leaking vacuum hoses and leaking fuel lines.
Whats the year? Possible problems.........Spark plugs, ign. wires, fuel filter. injector's dirty, timing. Theres a few more, but start with this.
the ignition module is on the distributer(the thing all the spark plugs wires go to)
On a 1995 Ford Crown Victoria : There is no distributor , it has an Electronic Distributorless Ignition System ( EDIS ) with ( 2 ) ignition coil packs that have four towers on each where the spark plug wires connect
EDIS , stands for Electronic Distributorless Ignition System That would be the ( 2 ) coil packs with spark plug wires on a 1996 Ford Crown Victoria that is part of the EDIS
The wires that go off the alternator are fused, meaning that will break the circuit by melting.
Just follow the ign. wires to the plugs, and use a spark plug socket.
When was the last tune up. Plugs, and wires, fuel filter, air filter. All of these or either one will cause this. Start with the plugs, try it, if still the same, then the wires, if still the same, then fuel filter and so on to the air filter. Good luck. If all fails, and the check engine lite is on, or if it is on now, get a read out first. Might give you some ideas.
