Where is the fuel pump relay and how can e serviced?


Description

*: ECM determines the start signal status by the signals of engine speed and battery voltage.
The ECM activates the fuel pump for several seconds after the ignition switch is turned ON to improve engine start ability. If the ECM receives a engine speed signal from the camshaft position sensor (PHASE), it knows that the engine is rotating, and causes the pump to operate. If the engine speed signal is not received when the ignition switch is ON, the engine stalls. The ECM stops pump operation and prevents battery discharging, thereby improving safety. The ECM does not directly drive the fuel pump. It controls the ON/OFF fuel pump relay, which in turn controls the fuel pump.

I believe that's a Speed Sensor issue.

Diag:
1. Ensure mainshaft and countershaft speed sensors are installed properly. Disconnect mainshaft speed sensor harness connector. Using a DVOM, measure resistance between sensor terminals.

2. If resistance is not 400-600 ohms, replace mainshaft speed sensor. If resistance is 400-600 ohms, disconnect 25-pin PCM harness connector "B". Check for continuity between ground and 25-pin PCM harness connector "B", terminals No. 15 (Red wire) and No. 14 (White wire).

3. If continuity is present, repair short to ground in Red or White wire between PCM and mainshaft speed sensor. If continuity is not present, reconnect mainshaft speed sensor harness connector. Measure resistance between 25-pin PCM harness connector "B", terminals No. 15 (Red wire) and No. 14 (White wire).

4. If resistance is not 400-600 ohms, go to next step. If resistance is 400-600 ohms, go to DTC
P0720 (FLASH CODE 9) . Check for loose PCM harness connectors. Replace PCM with a
known-good unit if necessary.

5. Disconnect mainshaft speed sensor harness connector. Check Red wire for continuity between 25-pin PCM harness connector "B", terminal No. 15 and mainshaft speed sensor harness connector. If continuity is present, go to next step. If continuity is not present, repair open in Red wire between 25-pin PCM harness connector and mainshaft speed sensor
harness connector.

6. Check White wire for continuity between 25-pin PCM harness connector "B", terminal No. 14 and mainshaft speed sensor harness connector. If continuity is present, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary. If continuity is not present, repair open in White wire between 25-pin PCM harness connector and mainshaft speed sensor harness connector.

Our 2003 Durango RT will not reverse while in reverse. The car just Idles there. We hear the car switch gears, but nothing happens. What could be problem?


This is one of two things, if the truck goes into drive and moves then you have trany problems and may need to have it rebuilt, if there is no movement in reverse or drive then it could be the transfer case or trany.

?¬Other transmission-related DTCs are set.
?¬Solenoid pack connector 5-volt supply circuit open.
?¬Sensor signal circuit has short to ground, short to voltage or open.
?¬Governor pressure sensor defective.
?¬Transmission fluid burnt or oil pan contains excessive debris.
?¬Governor pressure out of range.
?¬Transmission leaking internally.
?¬Defective PCM.
?¬Defective valve body.

Diagnostic Procedure
1.Using scan tool, read DTCs. If good trip counter for DTC P1756 is not displayed or displayed count is not zero, go to step 25. If good trip counter is displayed and displayed count is zero, go to next step.
2.Repair any other transmission-related DTCs before proceeding. If no other transmission-related DTCs exist, go to next step.
3.Check transmission fluid for proper level and for any debris. Fill or repair transmission as necessary. If fluid level and condition are okay, go to next step.
4.Start engine. Allow engine to reach normal operating temperature. Set parking brake, depress brake pedal and place gearshift lever in "D" position. Using scan tool, observe governor pressure sensor pressure. If pressure is greater than 3 psi (.2 kg/cm 2 ), go to next step. If pressure is 3 psi (.2 kg/cm 2 ) or less, go to step 20.
5.Turn ignition off. Install a pressure gauge at transmission governor pressure test port. Start engine. With gearshift lever in "D" position, observe gauge pressure. If pressure is 5 psi (.3 kg/cm 2 ) or more, go to step 23. If pressure is less than 5 psi (.3 kg/cm 2 ), go to next step.
6.Turn ignition off. Disconnect transmission solenoid assembly connector. Turn ignition on. Measure voltage between ground and 5-volt supply circuit at transmission solenoid harness connector terminal No. 2. If voltage is 4.5-5.5 volts, go to next step. If voltage is not 4.5-5.5 volts, go to step 19.
7.Turn ignition off. Disconnect PCM harness connector C2 (White). Measure resistance of governor pressure sensor signal circuit between transmission solenoid harness connector terminal No. 4 and PCM harness connector C2 (White) terminal No. 29.
