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

I have an02 Dodge caravan running fine and all at once it shut off now it has no fire it has 2.4 engine


Are you missing anything else? Engine cranking, you have fuel injector pulse?
At your ignition coil, brown wire with white tracer, should be hot engine cranking. Probably the same color wire for voltage at your fuel injectors. Use a test light to check for voltage.
If no voltage, check signal from cam and crank sensors. Some of these vehicles the computer has to see proper signals from both the cam and sensor or it won't ground the asd relay. The asd relay sends voltage to several systems including the ignition coil and fuel injectors. Any applicable trouble codes?

1991 Dodge Dakota fuel pump wireing. I removed pump and tested OK- Tried switching relays (all same in relay box) Still no cycling only a slight noise then silent. Ran 12-v (spiced) to left wire of 5.


engine cranking do you have spark at the plugs and fuel injector pulse? I don't know what testing you have done? I am trying to decide if more than one issue? Did you check voltage and ground at fuel pump connector, engine cranking? Initial prime is one thing but after that, if no rpm signal, no spark--no fuel injector pulse--no fuel pump. W/o rpm signal computer won't ground the asd relay. Any applicable trouble codes?
In my opinion, you can't bench test a fuel pump, I've seen faulty fuel pumps that would run up a storm on the bench but make no pressure when in the gas tank.

Check the ASD relay , auto shut down relay in the under hood fuse / relay box . The ASD relay supplies B+ voltage to the injectors an ignition coils plus other thing's ! This may be you device voltage code problem as well as the other codes

First question is are you getting spark to the plugs ?
Then are you getting fuel to the injectors, and injector pulse ?
Have you checked the ASD relay ?
I would check those things next.

1999 Dodge Ram 1500 318 engine no spark no signal to coil i changed cam positioner sensor and crank positioner sensor still no spark could it be a bad wire (ground)somewere


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 no spark or injector pulse sometimes it


You got a crank sensor at back,on top of bellhousing.
Injector pulse, I believe is controlled by hall effect sensor in distributor, as well as spark

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.
