I NEED TO FIND THE LOCATION OF A FUEL PUMP RELAY ON A 1990 FORD MUSTANG

i too replaced the heater core on my 1988 ford cv. the important point to rember is not to get overwhelmed. i ended up removing the whole dash, but not the stearingwheel. lable everything you remove....best to keep all parts seperated. mine looked like a nascar when i finaly got to the black plastic box where the core lives. i had to also remove some of the heating duct. once you open the box up, youll see the core. just sits in there. remove in and out hoses. very simple, but alot of work, thats why you must keep track of everything you remove. your engine coolant may be low, so add more when compleated. its been about 4 years now since i replaced mine.....i dont rember if the black box was rivited togeather or screwed togeather. if rivited, get a dremel tool with a grinder wheel, this will remove the rivites in good time. but the duct work was stapled togeather, i used 1/4 inch sheet metal screws to hook back up, works just fine.

it will be the heater hose that popped off...you will have to take the breather off to be able to get to it and put it back in place. usually they are held on with a clamp so if theres not one there you will need to locate that one or buy a new one

Check the inertia fuel switch located near the floorboard. It will have a button that you can press to reset the switch.

It is designed to be adjusted.. It actually is either threaded or is held on by a nut .... Unplug electrical connector and turn clockwise holding back of swith ( assuming it is the threaded type) if it has a nut there is generally two , one on front and one on back all you have to do in either case is adjus a little at a time ..the final goal is to adjust until brake lights stay on continuously then back off until they shut off....This procedure will insure correct adjustment.... Good Luck

inside the engine compartment with the main fuses

You have a bad starter solenoid. Check with your local auto parts store as well. Some of them test these for free. Good luck to you and thanks for using Fixya!

Principles of Operation The windshield wiper motor receive inputs from the following:

• multifunction switch
• lighting control module (LCM)
• ignition switch
• battery junction box (BJB)
• central junction box (CJB)

The following components are integrated into the windshield wiper motor:

• windshield wiper motor module
• high/low speed relay
• run/park sensor (Hall effect)
• washer pump relay

High Speed Windshield Wipers High speed is activated when the multifunction switch supplies ground to the windshield wiper motor module inputs. The windshield wiper motor module then supplies ground to the run/park sensor and high/low relay coil, activating the relay with voltage supplied from the ignition switch (RUN/ACC) through the central junction box (CJB). When the windshield wiper motor module receives voltage from the run/park sensor, it removes ground from the run/park sensor, deactivating it. The windshield wiper motor continues to operate from voltage connected through the run/park sensor until the Hall effect senses the magnet in the motor. When the Hall effect senses the magnet in motor the windshield wiper motor returns to the park position, the internal run/park sensor grounds the windshield wiper motor module input and the windshield wiper motor module removes ground from the windshield wiper high/low relay coil, deactivating the high/low relay and windshield wiper motor. The windshield wiper motor module continues to cycle the windshield wipers until the inputs from the multifunction switch are changed from the high speed position. Low Speed Windshield Wipers Low speed is activated when the multifunction switch supplies a specific ground to the speed inputs of the windshield wiper motor module. The windshield wiper motor module then supplies ground to only the windshield wiper run/park relay coil, activating it. When the windshield wiper run/park relay is activated, the deactivated windshield high/low relay connects voltage to the windshield wiper motor low input activating the wiper motor. The windshield wiper motor module continues to operate the windshield wiper motor in the same manner as in high speed, but in low speed with the wiper motor connected to the low speed input. Intermittent Speed Windshield Wipers The intermittent wiper speed is activated with grounds controlled by the multifunction switch inputs to the windshield wiper motor module. The windshield wiper motor module then activates the windshield wiper run/park relay coil and switches voltage through the windshield wiper high/low relay. The high/low relay remains deactivated, supplying the voltage to the wiper motor low speed input and activates the windshield wiper motor. When the windshield wiper motor module receives the grounded input, the motor continues to operate until Hall effect sensors senses the wiper motors magnet, which turns off the run/park sensor output to the windshield wiper run/park software, deactivating the relay and disconnecting voltage to the wiper motor. The windshield wipers remain parked until the windshield wiper motor module completes a time-out and then repeats the intermittent windshield wiper cycle. Washer System The windshield washer is activated by the internal wiper motor module when it receives a ground from the multifunction switch between the washer input. Dependent on the correct ground, the internal wiper motor modules activates the windshield washer relay (internal) by grounding the respective relay coil. When the relay is activated, it connects voltage to the washer pump while the washer level switch provides ground to the washer pump. Default Mode The windshield wiper motor defaults to this mode when the run/park sensor does not sense the hall effect magnet inside wiper motor. This can be caused by obstruction of the windshield wipers or a binding linkage. The windshield wiper motor will continue to operate in a high/low speed condition for a period of 60 seconds.

Hello. It seems either your Ford's speedometer cable is 'worn' and/or the speedometer, itself, is out of adjustment. Replace your Ford's speedometer cable first. If that doesn't help, then remove the 'instrument cluster' and take it to a specialty shop for repair. Good luck and keep me informed; if you want to.
