Replying to: ms_jetset (Nov 01, 2007 9:43 am) A few simple thAngs for now (been away for a week): Check fluid level and condition; after engine reaches normal op temp. Have a Check Engine Light on? get it scanned or DIY Self Test & Connector Location & pics, Bronco & Ford BEST PROCESS WITH DIAGRAMS! Source: by Ryan M http://fordfuelinjection.com/?p=13 do self test anyway; some faults do Not light the CEL since, "Don’t worry if the Check Engine Light is not on, the computer will store lesser important codes without flashing lights in your face." and; A technician that is unfamiliar with the EEC Self-Test can mistakenly believe that continuous Memory codes are not present when they really are. He may run KOER Self-Test and get a pass code (111) and not realize that KOEO Self-Test must be run to receive any Continuous Memory codes. He may run KOEO Self-Test while counting MIL flashes and misinterpret the repeated hard fault pass code (111) to mean that Continuous Memory does not contain any codes.

Source: by Ford via miesk5 -- from our Owner's Guide; "The E4OD and 4R70W transmissions are electronically controlled four speed automatic transmissions with overdrive. Transmission operation is controlled by the Powertrain Control Module (PCM). The PCM will automatically adjust transmission operation to make up for varying conditions. Several sensors located on the engine and transmission such as Throttle Position, Engine Speed, Vehicle Speed and Transmission Temperature are used by the PCM to shift the transmission into a higher or lower gear when required for the best performance and fuel economy. For example, you may notice that the transmission will upshift to a higher gear more quickly when the vehicle is first driven and has not reached normal operating temperature.The PCM also controls the transmission’s Torque Converter Clutch to further raise vehicle performance and fuel economy. The Torque Converter Clutch will engage when the transmission operating temperature and other conditions determined by the PCM have been met. Engagement of the clutch may be noted as a decrease in engine speed after an upshift has completed or when the driver has depressed the throttle while driving at a steady road speed. To help in troubleshooting, the PCM continually performs self-tests on the electronic control system and if any faults are detected, will store them in memory. The Transmission Control Indicator Light (TCIL), which is located on the gearshift lever, may flash steadily if a malfunction has been detected..."

Replying to: gator07 (Nov 15, 2007 3:46 pm) Do you have a check engine Light on? if so, post the Codes here for another reply. DIY Self Test & Connector Location & pics, Bronco & Ford BEST PROCESS WITH DIAGRAMS! Source: by Ryan M http://fordfuelinjection.com/?p=13 btw, A technician that is unfamiliar with the EEC Self-Test can mistakenly believe that continuous Memory codes are not present when they really are. He may run KOER Self-Test and get a pass code (111) and not realize that KOEO Self-Test must be run to receive any Continuous Memory codes. He may run KOEO Self-Test while counting MIL flashes and misinterpret the repeated hard fault pass code (111) to mean that Continuous Memory does not contain any codes. The engine temperature must be greater than 50°F (10°C) to pass the KOEO Self-Test and greater than 180°F (82°C) to pass the KOER Self-Test. To accomplish this, the engine should be at normal operating temperature One possibility is; Ford TFI Ignition Module; this is a good guess... but do the Self Test for Codes. Has that TFI Module been replaced Free under the recall? If you do not know, go to a Ford dealer and ask them to check using the VIN Code. or, DIY by registering at Ford and look to see what recalls are outstanding, plus; Owner Guides (Manuals), Bronco/Ford truck & other Ford vehicles, free, download Source: by Ford https://myford.fordvehicles.com/servlet/ContentServer?pagename=MyFord/Registrati- on/LogOnPage&BackToLogin=MyFord%2FHome%2FHomePage%26ord%3D15419550 Ford TFI Ignition Recall - the judge's order affected Fords manufactured between 1985 and 1995. http://www.summitlake.com/COMMENTARY/Ford_Ignitions.html?reload_coolmenus

Replying to: gator07 (Nov 20, 2007 12:40 pm) OK, do that self-test anyway; some codes may be stored w/out lighting the CEL ABS; & do a self-test too here; The 4WABS connectors is red, & is under the hood right beside the engine test connector 4WABS System Component Locations, DTCs & Self Test & Connector Diagram; 93-96 Source: by Steve83 http://www.supermotors.net/vehicles/registry/media/255501_1 ABS Self test connector location; ABS (RABS II) Self Test , Diagnostic Connector Location, (title in article is wrong in article) Source: by autorepair.about.com http://autorepair.about.com/library/faqs/bl180d.htm GL! |

i have a 87 full size Ford Bronco w/ the EFI 5.0 & O/D A/T. a few months ago i replaced the entire fuel system, tank, both pumps, filter, lines, & ERG system (rust problem). a few weeks ago the acuator rod in the column broke & since i couldn't find a new column (can't buy an acuator rod seperate) i installed an aftermarket ignition switch in dash. 2 weeks after i did the switch, the Bronco stalled at a light, i was idling & now the fuel pumps won't run. I've changed the ECM computer, the fuel pump relay (which if i jump the hot terminal to the out going, the pumps run) and all related fuses with no luck. Does anyone have any suggestions as to what may be keeping the fuel pumps from running?

Replying to: tjewertz (Nov 25, 2007 2:42 pm) Did you see any corrosion insde the FP Relay's socket? Fuel Pump Relay Socket Corrosion Info; spray it down with contact cleaner; They absolutely HATE moisture; also ck the EFI Power Relay (should be next to the FP Relay) for operation & corrosion. Next is the Inertia Fuel Cut-Off Switch (did you have a front end fender bender recently? see this by Bronco Rob & Steve 83; http://fullsizebronco.com/forum/showthread.php?t=38216 Fuel Pump Relay Operational Sequence; An inertia switch is used as a safety device in the fuel system. The inertia switch is located in the cab, generally under the dashboard on the right side. It is designed to open the fuel pump power circuit in the event of a collision. The switch is reset by pushing each of 2 buttons on the switch simultaneously (some models use switches with only one reset button). The inertia switch should not be reset until the fuel system has been inspected for damage or leaks. When the ignition switch is ON, it turns the EEC power relay ON. The EEC power relay provides power to the powertrain control module (PCM) and the control side of the fuel pump relay. Power for the fuel pump(s) is supplied through a fuse link or high current fuse attached to the starter solenoid (battery side). From the fuse link or high current fuse, current flows through the fuel pump relay and inertia switch to the fuel pump(s). The fuel pump relay is controlled by the PCM. When the ignition switch is turned ON, the fuel pump(s) will operate. If the ignition switch is not turned to the START position the PCM will shut the fuel pump(s) OFF after 1 second. The PCM will operate the fuel pump(s) operate the fuel pump(s) when the ignition switch is turn to START position to provide fuel while cranking. After the engine starts, the PCM will continue to operate the fuel pump(s) unless the engine stops, drops below 120 rpm or the inertia switch is tripped. GL! The pickup in the distributor can throw a code when it is intermittent or not working.. One of many reasons you should check your codes Have you done a code check? scan above for a DIY check that I have posted a few times here. |
