The ECM is located under the dashboard.
Try this before you replace the ECM change the pick up coil in the distributor the symptoms you are having usually happens when the pick up coil get hot and is defective. Here's how disconnect the battery, remove the distributor cap and you will see a disc like object below the rotor. It may have two or three screws holding it in place remove them and then remove the pick up cool. They start at $24.99

SOURCE: Ford Crown Vic p0300 random cylinder misfire

take a look at the EGR valve it could be either vacum controlled or electronic either way what seems to be the problem is that the valve is stuck in the open position until the engine warms up you can gently tap the egr valve with a small hammer or a screw driver and you can see that it runs smooth, now if the egr valve is vacum controlled replace the valve. if it is electronoc controlled replace the valve and the module for the egr valve.

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.

SOURCE: I need a spark plug wire diagram for 1987 ford 302

1987 Ford Crown Victoria 5.0L FI 8cyl

Duraspark Type Plug Wires
The spark plug wires used with the Duraspark type ignition system are 5 / 16 in. (8mm) in diameter to contain the higher output voltage. There are two types of wires used in this system, and some engines may have both types installed. It is important to properly identify the type of wire used for each cylinder before replacements are made.

Both types are blue in color and have silicone jacketing. The insulation material underneath the jacketing on some plug wires is a silicone layer separated by glass braid. The plug cable not incorporating the silicone layer is used where engine temperatures are cooler and are identified with the letter SE with black printing. The plug cables with the silicone insulation are used where high engine temperatures are present. These cables are identified with the letters SS with white printing.
Each spark plug cable, if original, is marked with the cylinder number, model year and date of cable manufacture (quarter and year). Service replacement wires will not have cylinder numbers, or manufacture date.


On any vehicle equipped with a catalytic converter, never allow the engine to run for more than 30 seconds with a spark plug wire disconnected. Unburned fuel in the cylinder may ignite in the converter as it is exhausted and damage the converter.

When removing spark plug wires, mark and tag the individual wires. Grasp, then slowly, twist the insulator back and forth on the spark plug to free the insulator. Do not pull on the wire directly as it may become separated from the connector inside the insulator. Special tools are available which can help ease plug wire removal, and prevent damage to a cable.

When installing a new set of spark plug wires, replace the wires one at a time so there will be no confusion. Start by replacing the longest wire first. Route the wire exactly the same as the original.

I have engine from 1984 ford crown victoria. it isnota a302 ci. i was told it is a 351 windser when i brought it. how many engine size came with the 1984 crown vic? or what engine do i have?


Crown Victorias that year came with two engine options.
The regular Crown Vic had a 302 cubic inch engine.
The Police version had a 351W.
The 351W is a much better, stronger engine.
The easiest way to tell at a glance is to see if you can access the bottom thermostat housing bolt with a socket. If you can it's a 351W. If you can only get a wrench on that bolt, then it's a 302.

What is the device on a 302 5.0 1984 ford ltd crown vic it is located lower left on engine and is belt driven under the air conditionr pump


For a while in the early days of pollution control there used to be an air pump which forced air into the side of the catalytic converter in order to lower the percentage of bad stuff in the total output of the exhaust. Perhaps that is what you are looking at. Most were disconnected almost immediately but no later than the first replacement of the converter.

Would like to change oil pan on 1990 ford crown vic 5.0 302 cu/in how do i begin


Before you do, why do you want to change the pan? OK then, consider the sump, is it front or rear? Do you have room to drop the pan 6 inches and get it out? The oil sump is at the bottom of the pan. If not, you have to pull the motor mount bolts out and jack up the engine. Then pull it out. When you put in the new pan, use no adhesive on the gasket, none. Bolt that baby up, drop the engine, tighten everything up, fill her up with oil, you should be all set.

1987 crwn vic 5.0 l, 302, Engine runs for 5-10 minutes and shut down. Cranks but will not restart. After 12-24 hrs car will start again and run for 5-10 minutes and process repeats. When the car shuts off...


this is tough, two things I can think of, the first is the coil, if it is not ground good there wont be a good spark or a defective coil,,,, but i am leaning more to it being the timing chain jumped a cog,,, the computer would start the engine advansed but as the engine warmed it would ****** the spark ,,, after 5-10 min. it would quit,, this I would if it si a higher milage car.
