The FP relay is in da IRCM (formerly called da CCRM) and it is Mounted forward of the airbox The CCRM is not usually serviceable. But if you want to take a shot at it see Joe's info in Link below
Troubleshoot & Repair Your Malfunctioning Integrated Relay Control Module (IRCM) - by - J o e F r a z i e r NATO Member "Joe Cool
CCRM = Constant Control Relay Module , IRCM = Integrated Relay Control Module;. This relay contols the fan, fuel pump and A/C clutch if i'm not mistaken.
the fuel pump relay is tied into the IRCM on 94-95s; Since 1986, Ford has used, on several models, an Integrated Relay Control Module (IRCM) to operate the fuel pump, engine cooling fan and compressor clutch. During the early 1990ís, the
name was changed to Constant Control Relay Module (CCRM). The module has a 24-pin connector .

Relay? Do you mean the Test Connector?
4WABS System Component Locations, DTCs & Self Test & Connector Diagram; 93-96; The 4WABS is located at the left-hand side (driver's side) of the engine compartment and marked ANTI-LOCK TEST - in my 96 it is near the hood hinge

#85 of 352 abs lite still on
Dec 03, 2007 (5:41 pm)
I decided to replace the abs sensor($20) on the differential(guy at ford dealer said they go bad quite often) and it did not help.I had my doubts, but gave it a try.The code I got was a 17(possible relay, fuse, intermittent valve failures, opens or shorts to ground,high resistance valves etc) when I did the test prior.I tried swapping the horn relay with the ABS relay in the Distribution box which had the same numbers on them and that did not make the lite go out.I only started the vehicle in the garage which I felt should be enough to make the lite go out if the sensor or relay was the culprit.Are there any resistance readings on the wires comeing from the rear sensor that I should look for.One reads 5k and the other has very high res.Would like to fix the problem if possible.thanks

vehicle starts and runs but will start to stall out from a stop. will often stall out when slowing down. did all summer. this winter i noted that the the battery gauge would start to go down first and then it would quit.the needle sits on the M but when it starts the stall outs it sits on the R. it did oscillate a couple of time at night and the gauge went up and down as the lights brightened and dimmed. one mechanic stated he thought it was the trottle sensor. but there has been a few times where after it has done the stop and i restart that it just cranked and cranked and cranked, with no restart, but as soon as i turn it completely off and hit the key it starts back up.
ignition module? or stick of dynamite

17 Reference Voltage/Intermittent Valve Fault
∑ 30 amp fuse open.
∑ Intermittent connections to battery, main relay or ground. driver's side radiator support and;
∑ Main relay coil or contacts open. MIESK5 note; check relay contacts FOR corrosion pull relay again & ck ;
also see Fig. 12 and on (in below LINK) for pin point tests of CODE 17 -∑ Open or short to ground in Circuit 532 (O/Y). ∑ Open or short to ground in Circuit 599 (PK/LG).
∑ Open or short to ground in Circuit 601 (LG/PK).MIESK5 note; FROM FUSE PANEL 30 amp fuse
∑ Short to ground through anti-lock hydraulic control unit.
∑ Intermittent valve failures.
∑ High resistance valves.
So, ck that Relay's contacts (not the relay's contacts, but the connector's contacts.)
Here is Chilton's wiring diagram via autozone; you will see all above ckts and color codes in Fig. 8: 4-wheel ABS testing-1993-96 Bronco models

Also, R values for all in Fig. 10:
Read thru all of that Chilton stuff; can save you $ btw, the rear ABS sensor on the diff would give Code 57.

Take it to get a free batty, alternator, etc check at AutoZone, Also Adv Auto may do it free too;
possible battery, grounds, connectors, etc.
Did you do the Self TEst for Codes? if not, get it done free at the AZ and post results here.

Ck with folks you bought the long Block from to see if the cam is for rollers.
Most likely; Could be just a head gasket which has blown between those two cylinders, sticky valve(s) etc.
or worse; Another possibility is that the camshaft is broken in an area that operates valves for two adjacent cylinders. not likely..

A leakdown will determine whats going on in those cylinders,look inside the radiator for any "brown foam" to see if the head gasket is blown.Aside from that the leakdown will tell you all thats going on
