1) Replace the radiator, it won't get better and will cause BIG problems later on, the plastic and aluminum radiators are fairly cheap (check rock auto for price) 2) Replace the TFI (thick film ignition) module mounted on the side of the distributor. Very common problem with Ford ignition systems Something in the module opens when it gets hot, then works fine when it cools off. It's like someone turns the key off while driving, no warning, sputtering etc.You will need a thin wall 5.5 mm socket to change the module. Most auto part stores have a special wrench setup just for changing the module and it only costs a couple of bucks and makes the job a breeze. make sure you put plenty of dielectric grease on the mounting side of the module for proper installation (usually included with the module)
The ignition system on your 5.0L uses a distributor type system and will include the following components:
Ignition control module (ICM). Depending on the year of your specific Ford, it'll have a inner-fender mounted ignition control module or a distributor mounted ignition control module. hot sure which you have.
Ignition coil. you replaced it.
PIP (Profile Ignition Pickup) sensor. This is Ford's name for the crank sensor and is mounted inside the distributor. The most common name for this component is the pick up coil.
Distributor cap and rotor. you replaced
Spark plug wires. you replaced.
The thing to keep in mind about the ignition system is that all engine cylinders must get spark and the one thing that will stop the ignition system from creating spark on a wholesale scale is a BAD crank sensor.Have you pulled a plug then using some insulated pliers grounded it to the vehicle and turned it over to see if you have spark, that'll tell you alot.takes two people of course.Best of luck and hope this helps.
Hi, You did not mention what size engine is in this vehicle or mileage, but your starting issue sounds like it is related to the ignition control module. I am assuming the fuel pressure is ok at this point. The control modules are known to act up over time and can cause a driveability problem that your experiencing. The module will look like this;
Scanner must be used to turn this light off almost every parts stoor will do this at no cost to you. Hey wish you were close to me that $550. looks like a good sum to pay at 40,000. I would not pay that at all. Have the check engine light turned off and drive it till it comes on again then return to the auto parts stoor and they will read the failure code and tell you what part you need.
