Question about 1994 Dodge Ram
All fuses good plugs and wires under 6 months old new coil pack . when i try to start the truck i get only a short burst of power to the coil pack and no spark at all.i even put a test light on the coil pack it self ( got nothing)
SOURCE: 94 dodge ram pickup 1500 v-6
Many dodge models actually have two o2 sensors. I'm not sure if this applies to your model. If so, one is on or just downstream of the exhaust manifold. The other on the outlet pipe of the catalytic converter.
The PCM compares the readings and adjusts the fuel/air mix to keep the catalytic converter operating at max efficiency.
A malfunction in any portion of this sub-system could cause your symptoms. So let's run a test on the o2 sensor(s).
To do this manually, get a pad, a pen, your keys and get in your truck.
(the procedure for entering diagnostics may vary, but this works for the dodges I've worked on)
Question: Of all the possible causes, why did the o2 sensors get picked as the cause? Is there more to the story?
Any way, run the tests, perform the diagnostics and get back with me, we can go from there.
Hope this helps

you can try changing the ignition coil, I own a 97 Dodge 1500 and mine did the same and thats what i had to do.
