Question 1986 RANGER 2.3 EFI -WHERE IS THE EEC-IV?

Hello!

CAN ANYONE TELL ME PLEASE....EXACTLY WHERE THE EEC-IV IS?

1986 2.3 FORD RANGER Gas / EFI / 140 CID
4-Cyl. / 5-Speed / SOHC / base Cab.
_______________________________

I swear by Motorcraft electrical parts and have been using them for the life of this truck (original owner) in the past, I have bought TFI modules from Ford for less than $75.00. Today, I called my local ford parts and now they want $198.65, whereas Autozone for $46.99. 26 years for a truck that's seen better days, bad valves and pistons, 155,000 miles, sorry, it's autozone for me. It would be so great if it was the TFI, but I also want to test the EEC-IV, the component to the TFI.

I want to remove, and take my Distributor Coil, TFI (Ignition control module) and my EEC-IV (Electronic Engine control) part to autozone to test.

Having a 1986, I have personally replaced about four TFI's on this truck. They are infamous for rangers to fail from time too time.

I recently replaced my fuel filter, but not my in-line pump, I feel I'm getting fuel to the injectors, but it cranks, but does not turn over, which leads me to believe this could be a spark issue. Spark plugs and wires are fine. I have not tested my fuel pressure yet.

My search for the location of this EECV-IV is confusing. Yes, I do have the fuel pump relay, the blower fan relay, and the ECC (or EEC) relays on passengers' side fender well, in the same area.

Some say the EEC-IV is in the inside cab, middle, under the dash. Well, I looked and I did see a little box with wires going to it attached to the dash metal frame, but this is not what I believe to be looking for, which is a little bigger. Others say it's in the very right passengerís sidekick wall, behind the plastic cover.

SO PLEASE....CAN ANYONE TELL ME EXACTLY WHERE THE EEC-IV IS?

Thank You !

tomw has a very good reputation on FTE.tomw has a very good reputation on FTE.tomw has a very good reputation on FTE.tomw has a very good reputation on FTE.
The EEC-IV for 1985 is behind a panel down by the passenger footwell. While sitting in the seat, it would be to the right of your feet. One or two screws, and 'walk' the lower trailing edge of the panel out from underneath the sill plate, and it will be found upright, along with the fuel pump relay. A 1986 model may have the same layout. Or not.

p.s. EEC-IV processors are not known for messing up. You may need the pickup inside the distributor bowl as the connector is known to turn to mush after it ages, leading to intermittent problems.
