TOOLS
TFI Wrench
This wrench is the only way to remove and replace a TFI module.� The TFI bolts have 7/32" / 5.5mm heads but no normal socket fits into the TFI, so you have to buy this special tool. The older design is smaller and used with a 1/4 inch drive socket set.� The design changed to this newer hand model.� The TFI never needed to be torqued down with a socket set, and this new design is simpler to use.� To remove the TFI simply remove the two bolts, and slid the module downward.� You MUST slide the TFI down before you pull it away from the distributor or it won�t come off correctly.
TFI Tester
This is a TFI tester.� Don�t expect a wonder tool for diagnosis of intermittent TFI problems.� This tool will only show a completely failed module or a TFI that will start a vehicle.� I haven�t seen any TFI testers that will show a partly failed or intermediate problem.� You connect a 9-volt battery and the TFI in question.� Then you touch the yellow clip to the Stator pins.� An LED will come on if it�s a �good� TFI and no light if it�s failed.
Upper Intake Socket
This tool is made to help remove the upper intake from your vehicle.� It is not needed for all Ford intakes.� Some intakes have longer bolts that are easier to reach.� But if you can only see 4 or 5 of the bolts holding the upper intake on the engine, you�ll probably need one of these.� The bolt that you can�t see way down in the middle has a Torx 40 head.� It is possible to make a chain of 3/8 or 1/4 drive socket pieces to reach these bolts.� But this page is about all the cool tools you don�t have yet.
Fuel Rail Disconnects
You must buy or borrow disconnect tools to disassemble the fuel rails.� These are sold as disconnects for Ford fuel and AC fittings in most stores.� There are two different styles to this tool.� The cheaper version is shown in the first photo below.� They are one-piece design.� The more expensive version is a two-piece design, it springs open and closed.� Both versions work very well.
Here are a few different views of these fittings to ad
your in there removal.
Here is a visual explanation on the removal of these fittings.� I have found that you have to twist while pushing the disconnect tool into the cage.� This helps ensure the spring spreads over the female fitting.� Once the spring is spread over the female fitting, you have to pull the two ends apart.� They are relatively durable fittings so don�t be afraid to use some force to help the O-rings slide.� Remember these are sealed to over 100PSI and they have been connected for how long?
60-pin Brake-Out-Box (BOB)
If you can�t find a problem or find yourself testing sensors every month this is the tool for you.� This mounts between the EEC and the harness.� You bolt the 60-pin connector to the BOB and then mount the BOB to the EEC.� As you see in the picture there is a panel with 60 holes in it.� You simple take the probes from you voltmeter and stick them in the holes that correspond to the sensor or wiring you are checking.
SnEEC-IV
This is probably the coolest way to test and diagnosis problems with your EEC-IV vehicle.� This is the ultimate Brake-Out-Box, in a class called data-loggers!� You don�t need a voltmeter, and all your friends will be jealous.� Just like the BOB you mount the SnEEC between the 60-pin connector and the EEC.
That is where the similarities end.� You have two options for checking EFI system status.� There is a remote mounted switch that when you press the button it begins to record data.� Say you have an intermediate problem you cant find.� Drive the vehicle around, when the engine starts acting funny activate the switch, and the SnEEC records the event for further study.� I know you already scrolled down to see the pictures, so you know that the SnEEC connects to a computer for reading.� Two choices for reading the information.� You can record the data; remove the SnEEC for diagnosis on the desktop computer. �OR if you like cool toys you can leave a laptop computer installed in the vehicle.� You can read all the senors at once, engine RPM, vehicle speed, and even hook up a wide band oxygen sensor for testing and tuning of your EFI system.� This SnEEC system can show recorded events on the laptop or it can read live data.
