Trying to locate spark plugs on 99 crown vic police interceptor engine

Bad ignition coil on cyl 8

That is a transmission code...

P1747 (EPC Shift Solenoid). Not uncommon for police interceptors...

Here is a discussion of other possible causes:

The police package interceptors had a common problem with the fans seizing up. There was a TSB ford released to correct the issue which called for the replacement of the electric fan assembly with an updated fan assembly.

The PCM is programed for the LS engine parameters and now that you have changed engines the signal from the new engine are out of parameters> Either see if you can get the PCM reprogrammed at a dealership or purchase a new PCM and program the chip with the police engine interceptor to the vehicle> you may also return to the place where you got the engine and purchase the PCM for the police vehicle.

I suggest that you look this up and the term interceptor refers to police package as in heavy duty suspension,brakes transmission etc. http://en.wikipedia.org/wiki/Ford_Crown_Victoria_Police_Interceptor

you can get a A/C Delete kit for a Ford 4.6 liter. the 4.6 v-8 accessory drive system is all the same. You may also be able to run a line of string around the pullys, take it to your local auto parts store and they can match it up. I recomend the kit,

you will need to change the fuel pump had that problem with one of the customers,if my info is of any help to you please leave me a comment,thankyou.

i have ran into 2 issues in these vehicles---if it binds while sitting still also, check the steering shaft, i have found the u-joints in the shaft tighten up and binds dangerously tight---if they are free, sounds like you may have a steering box issue or restriction in a line---hope this was helpful!!

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:

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)

I hope this helps!

Have you checked the fuel filter. Fuel pump will pressure up, but fuel filter could be clogged and not work without the pressure of the fuel pump.
