No fuel pressure asd&pump relays energized

On Chrysler products the fuel pump relay only turns on when that ASD relay is energized by the computer and that happens during cranking, 3 to 5 seconds after you're done cranking or with the engine running. It is very common for the ASD relay to go bad and not allow the fuel pump relay to come on. Also, if the crank sensor has failed it will not allow the ASD relay to energize. These sensors and relays can be observed with a fairly inexpensive scan tool. If you go to a parts store to purchase one I recommend you ask 2 questions. 1) Will it read relays and sensors, live data stream? and 2) is the screen clear and easy to read with few abbreviations? I own 3 scan tools, 2 were under a hundred bucks, better one i think around $150.00 Cheap one is for lending to young kids with good eyes. LOL
I hope this helps

There are two fuses for the fuel pump relay. One fuse is load side of relay, that fuse also sends voltage to load side of asd relay, the asd relay sends voltage to several systems, two of which are the fuel injectors and ignition coil. I'm not telling you to replace, anything, but, you need to do some testing.
The other fuse goes to control side of relay, smaller amp fuse. I don't know the amp rating of the fuse that keeps blowing.
See that fuse, it supplies voltage to load side of fuel pump relay and also to asd relay.

on many cars , you need to crank it.
some have the prime key on for 3 seconds.
on jeeps.
check fuses first
check the ASD relay, if it dont energize the pump relay will be dead.
ASD >>> Fuelpump relay.

on jeeps, the ASD drops after 3 seconds, if the PCM sees errors.

I see you replaced the fuel pump , spark plugs an wires , fuel fliter an checked ignition coil pack , Connections ,ASD relay . And everything checks OK ?????? How did you check these thing's ? Testing electrical circuits with a DVOM - digital volt ohm meter ? Fuel pressure testing the fuel pump before replacing ? Does the vehicle have spark ? How about hooking up a scan tool that can view engine sensor data .A bad coolant temp sensor could cause hard starting. Did you check the dark blue with yellow trace wire at the PCM connector 2 pin 67 . This is the PCM control side of the ASD relay . Do you know how a relay works ? how to test at the relay base ? where in plugs into.

did you check all fuses with a meter ?
you are new to jeep repairs.... here are some facts.
jeeps have ASD relay.
when car dont start, see what the ASD relay is doing
do not throw parts, you picked the most hard and expensive thing to change on a lark. why do that?
the fuel pressure gauge is $20 and takes 5min to see that fuel pressure is good. not pulling the tank and pump. for fun.
why do that.? (seen 100000 times on forums, this....)
here is mr. ASD, and what to check.
the ASD can cut fuel and spark for many causes. x8

automatic shut down relay.

does the relay close cranking? y/n ?
if yes, does it then drop out cranking, y/n?

those are the first 2 tests on all jeeps 1993 to now.

each check discovers what is wrong
so does attaching any OBD2 scan tool and cranking
for 5 long seconds and behold, DTC errors.
got DTC errors cranking/??

BINGO x10.

The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s). With certain emissions packages it also supplies 12-volts to the oxygen sensor heating elements. The Fuel Pump Relay is a separate relay controlled by the ASD relay input to the PCM. Fuse #12 (10amp) provides 12 volts to the coil side of both the relays and the ignition switch. Fuse #6 (30 amps) supplies 12 volts to the output side of the relay. Fuse #16 (15 amp) from the relay output to the Oxygen Sensors and Fuse #26 (15 amp) relay output to the PCM. Fuse #24 (20 amp) is Fuel pump relay output to fuel pump. Fuse #19 (10 amp) supplies 12 volts direct to the PCM.
look for burned or melted wires in the offending circuit.
sounds like you wiggled a wire while installing new relay.

ASD fuse is called an AUTOMATIC SHUT DOWN FUSE. The ASD sense circuit informs the PCM when the ASD relay energizes. A 12 volt signal at this input indicated to the PCM that the ASD has been activated. This input is used only to sense that the ASD relay is energized.
When energized, the ASD relay supplies battery voltage to the fuel injectors, ignition coils, and the heating element in each oxygen sensor. If the PCM does not receive 12 volts from this input after grounding the ASD reley, it sets a Diagnostic Trouble Code (DTC).

Well in a short term, you have a short circuit somewhere. Here is a detailed toturial for you. Please rate this post, thank you.

Automatic Shutdown (ASD) sense - PCM Input

The ASD sense circuit informs the PCM when the ASD relay energizes. A 12 volt signal at this input indicated to the PCM that the ASD has been activated. This input is used only to sense that the ASD relay is energized.
When energized, the ASD relay supplies battery voltage to the fuel injectors, ignition coils, and the heating element in each oxygen sensor. If the PCM does not receive 12 volts from this input after grounding the ASD reley, it sets a Diagnostic Trouble Code (DTC).

Automatic Shutdown Relay - PCM Output

The PCM operates the Automatic Shutdown (ASD) relay and fuel pump relay through one ground path. The PCM operates them by switching the ground path for the solenoid side of the realys on and off. Both realys turn on and off at the same time.
The ASD relay connects battery voltage to the fuel injectors and ignition coil. The fuel pump relay connects battery voltage to the fuel pump.
A buss bar in the power distribution center (PDC) supplies voltage to the solenoid side and contact side of the relay. The ASD relay power circuit contains a 20 amp fuse between the buss bar in the PDC and teh relay. The fuse also protects the power circuit for the fuel pump relay and pump. The fuse is located in teh PDC.
The PCM controls the relay by switching the ground path for the solenoid side of the relay on and off. The PCM turns the ground path off when the ignition switch is in the Off position. When the ignition switch is in the On or Crank position, the PCM monitors the crankshaft position sensor and the camshaft position sensor signals to determine engine speed and ignition timing (coil dwell). If the PCM does not receive the crankshaft position sensor and camshaft position when the ignition switch is in teh Run position, it will de-energize teh ASD relay.
The ASD relay and fuel pump relay are located in the PDC near the battery. The inside top of the PCD cover has a label showing relay and fuse location.

ASD and Fuel Pump Relays

The following description of operation and tests apply only to the Automatic Shutdown (ASD) and fuel pump relays. The terminals on the bottom of each relay are numbered.

'------------------'
' __85 ___________'
' __87A '87 '30 ___' Sorry for the crudeness of this. This is supposed to
' __86 ___________' be the relay terminals!
'------------------'

OPERATION
- Terminal number 30 is connected to battery voltage. For both the ASD and fuel pump relays, terminal 30 is connected to battery voltage at all times.
- The PCM grounds the coil side of the relay through terminal number 85.
- Terminal number 86 supplies voltage to the coil side of the relay.
- When the PCM de-energizes the ASD and fuel pump relays, terminal number 87A connects to terminal 30. This is the Off position. In the off position, voltage is not supplied to the rest of the circuit. Terminal 87A is the center terminal on the relay.
- When the PCM energizes the ASD and fuel pump relays, terminal 87 connects to terminal 30. This is the On position. Terminal 87 supplies voltage to the rest of the curcuit.

TESTING
The following procedure applies to the ASD and fuel pump relays.
(1) Remove relay from connector before testing.
(2) With the relay removed from the vehicle, use an ohmmeter to check the resistance between terminals 85 and 86. The resistance shoud be 75±5 ohms.
(3) Connect the ohmmeter between terminals 30 and 87A. The ohmmeter should show continuity between terminals 30 and 87A.
(4) Connect the ohmmeter between between terminals 87 and 30. The ohmmeter should not show continuity at this time.
(5) Connect one end of a jumper wire (16 guage or smaller) to relay terminal 85. Connect the other end of the jumper wire to the ground side of a 12 volt power source.
(6) Connect on end of another jumper wire (16 guage or smaller) to the power side of the 12 volt power source. Do not attach the other end of the jumper wire to the relay at this time.

WARNING: DO NOT ALLOW OHMMETER TO CONTACT TERMINALS 85 OR 86 DURING THIS TEST.

(7) Attach the other end of the jumper wire to relay terminal 86. This activates the relay. The ohmmeter should now show continuity between relay terminals 87 and 30. The ohmmeter should not show continuity between relay terminals 87A and 30.
(8) Disconnect jumper wires.
(9) Replace the relay if it did not pass the continuity and resistance tests. If the relay passed the tests, is operates properly. Check the remainder of the ASD and fuel pump curcuits.

__________________________________________________ _______________

I know you said you replaced the relay, and this is a test procedure for the relay, but I have bought bad parts in the past. The description before the test procedure at least gives you an idea of what components are wired through and controlled by the relay. One of those may be faulty. Email me if you want or need wiring diagrams and I should be able to scan them and email them to you.

I hope this helps.

Please rate this post, thank you

You have two relays there...the fuel pump relay and the pump bypass relay. Did you check both? Also, did you check the resistor on the drivers fender back near the master cyl? Both relays are powered by the asd relay that is energized by the crank position sensor via the computer.
Also check the connections for the relays underneath the power distribution center.
