New coil getting power no ground or spark what could cause this? 01 ram 1500 5.2

 

Does the fuel pump prime? If it does, crank sensor is prolly toast.

 

I changed the crank sensor

 

Any chance you can be a little more vague? LOL Your original question and your answer.

 

I'm having the same problem w/ my 2000 5.2 4X4 When I turn the key on, I can hear the fuel pump come on for a few seconds. When I checked for spark at the plug (removed plug and grounded) I have no spark... Could this be a crank trigger problem?? I have not pulled the cap off yet and I don't know if the coil could be bad (how do you check it ??) Had no problems with the truck until yesterday morn. Was really cold out so I started it up and started scraping the snow and ice off the windows and it just stopped running (ran maybe 15-20 sec.) I started it up again and the same thing happened I was thinking fuel line freeze up, but today was much warmer and it still would'nt start so thats when I checked for spark.. Any help??????? Thanks Larry

 

Make sure you are getting power to the coil. Without the engine running, you will only have it for about 3 seconds though, so, having an extra set of hands is almost a requirement.

Check and see if you have spark from the coil...... Just stick the spark plug in the end of the coil wire, ground it good, and crank the engine.

 

ive changed my crank sensor and pcm....after i changed the pcm(got it from the junkyard) it ran really rough and stalled repeatedly about 5 times now it wont do anything....there is power going to the coil but nothing coming out...i tried the coil on my friends truck and it works fine.... he tried my pcm and the one i got from the junkyard on his truck and it would not start.... im afraid to try his pcm on my truck cause i think somethin on my truck is frying the pcm...... what should i try ??? could my wiring harness have a dead short ?

 

oh and the fuel pump primes... it has presure and while checking around i noticed frayed wires on the cam sensor and changed it....that was before i changed pcms

 

Why did you cahange the PCM to start with?

 

its at a mechanics my pcm is fried.....he has a fancy scanner... they are saying there is a dead short somewhere in the coil curcuit..ive friend 2 pcms trying too fix my truck.... i hate electrical proplems arggg
