SOURCE: 97 Dodge Ram Pick up cranks ok engine won't run

try checking all the ground circuits comming out of the PCM. and its also not common for a ground driver in the PCM to fail on dodges. also i have seen crankshaft sensors short out and take out pcm communication. so i would start by unplugging any sensor that runs off the 5v supply until the pcm wil talk to the scanner. if you unplug a sensor and communication returns to scanner then replace the sensor. and dont forget to check for good power and ground at the data link conector and PCM

Check the ASD relay in the fuse box. Swap it with the starting relay. If the engine fails to roll over. Thats your problem. If not, check and see if your fuel injector connectors have voltage to them if not its a bad PCM. Hope this helps.

I have a 2005 dodge neon that will crank but wont start. I have replaced the cam shaft sensor, crank sensor and the coil pack. Iam also not getting spark to the coil pack. Any suggestions?


Primary voltage to several systems, including the ignition coil, dark green wire with orange tracer. That voltage comes from asd relay. There is a fuse for asd relay. To check for voltage the engine has to cranking. The control side of asd relay, the computer has to ground it before it will energize. Did you check wiring circuits for cam and crank sensor connectors before replacing sensors? Are there any applicable trouble codes?
Are you ok with testing wiring circuits?

97 neon cranks won't start changed crank cam sensors also the coil pack still no fire to plugs


Possible ASD relay? This is an auto shut down feature for many dodges and can cause a lot of problems. Ensure all fuses are good as well. Just swap a relay from another position into the ASD spot. Use a relay that is not used to start the vehicle.

How do I fix my asd relay problems on my 2000 Dodge Ram 1500 pick up truck


Note the diagram. The left side of asd relay, line with arrowhead, is load side of relay, when the relay is energized that line moves to other terminal and it carries voltage to everything the asd relay controls. The control side of relay, right side, is that coil symbol, that side needs voltage and ground. The computer grounds the control side of relay if it sees proper signal from crank and cam sensors. Not only check those fuses, use a test lite check fuse circuit for voltage, as you can see, one fuse is hot all the time, the other goes hot with the key on.

P1389 code on a 97 dodge ram 4x4 5.9. Replaced the pickup, ignition wire, asd relay and crankshaft sensor. Cap and button looked great and are only a couple months old. Truck will crank not start. Gas


are you sure that you changed the ASD relay? that code is for no signal from the ASD to the PCM. Check that you have constant 12v at the relay base and that you have switched voltage when the key is on at the relay base, then make sure you have continuity to ground at the relay base. If the relay clicks when the key is turned on then the internal coil is making and should be sending a signal to the PCM when the key is turned on.

1999 Dodge Ram 1500 cargo van will not start


If it cranks good but won't start, have a helper crank it while visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure. Also, check fuel injector pulse.
If your missing several system, an example, at the ignition coil and fuel injectors, engine cranking, check the dark green wire with orange tracer for voltage? If no voltage that leads back to asd relay. I'm not saying the relay is faulty. Your computer has to see both the cam and crank sensor signals or it may not ground the asd relay. The asd relay supplies voltage to several systems.

1997 dodge ram won't start. My fuel pump does not run and coil won't spark. Iv'e checked fuses and relays and they look fine. Could a bad fuel pump cause the asd to kill power to the coil?


First check any ignition/fuel related fuses. Check to make sure you have 12 volts coming into the pump and coil. If nothing to the fuel pump replace the fuel pump relay - if you do have power to the fuel pump then replace the pump. If nothing is coming to the coil it is either an ignition relay or a wiring issue. If you have 12 volts to the coil but no spark then replace the coil.
Also the fuel pump/relay would not kill the coil.

92 dodge ram 150 5.2 this truck has no spark no injector pulse has no 8 volt computr to rank sensor, no ground b/y wire to asd relay.


TRY UNPLUGGING DISTRIBUTOR PICKUP CONNECTOR AND SEE IF 8V SUPPLY RETURNS..IF NOT,TRY UNPLUGGING VEHICLE SPEED SENSOR IN TRANS..THESE SHARE THE 8V SUPPLY CIRCUIT TO CRANK SENSOR ONE OF THEM MAY BE SHORTED..THERE IS NO GROUND TO ASD RELAY BECAUSE THE PCM MUST SEE CAM AND CRANK SIGNALS TO GROUND THE ASD RELAY..I HOPE THIS HELPS
