I have a 96' crown vic 4.6 no spark

The Crown Vic has issues with the spark plug wires, replace them if the spark plug connector boot looks burned or has holes burned into it. Replace just one wire at a time!! Also do you have a check engine light? You should if your engine has a misfiring cylinder.

The timing on all 96 and newer vehicles is computer controlled so its very rare for one to jump time.One thing bothers me you said you can see spark coming from one of the top of the plug,thats a problem.Check the plug wires because you must have one bad if you can see it.If they are all in bad shape replace them then see how it runs,it might just fix all the problems.

ck 4 fuel press. spark inj. pulse ect.!

pass side rear plug

I would visually check for spark at the plugs, to make sure spark is getting to the plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse.
How long since a tune-up? Any applicable trouble codes?

Hi,
I'm a little confused. You want it to come on?
The check engine light comes on when you have a problem with the engine or drive train. If it hasn't come on, that's a good thing. It's not meant to be a reminder to check oil or anything like that.,, Please clarify? Thanks!

I ~think~ the 1999 is the same as the 2000 (mine is a 2000 P71)

The 2000 CVPI (Crown Vic Police Interceptor) owners manual recommends the following:

Engine Oil - Motorcraft SAE 5W-30 Super Premium Motor Oil 5.0 quarts

Transmission Fluid - Motorcraft Mercon V ATF 13.9 quarts (fluids Mercon & Mercon V are NOT INTERCHANGEABLE, DO NOT MIX)

Fuel Tank - 19.0 gallons

Break Fluid - DOT 3


Rear Axle Lubricant - Motorcraft 80W-90 Premium Rear Axle Lubricant 3.75 pints (add 4 oz of Additive Friction Modifier C8AZ-19B546-A or equilavent meeting Ford Spec. EST-M2C118-A for complete refill of Traction-Lok Rear Axles)

Engine Data - 4.6L V8 Engine
Cubic Inches - 281
Required Fuel - 87 Octane
Firing Order - 1-3-7-2-6-5-4-8
Spark Plug Gap - 1.3-1.4 mm (0.052-0.056 inch)
Ignition System - Coil On Plug
Compression Ratio - 10.0:1

I hope this helps!

look under the hood in the big fuse panel and look for High beam headlight relay the relay is more than likely bad

I would try to replace your spark plugs, and spark plug wires, My 88 Vic did the same thing...now it runs like a champ....you could also try fuel injector cleaner.

not coil coil it wouldnt fire at all it is either a plug or a wire replace the wire and plugs and that will fix it
