I have 2001 dodge ram 1500 5.9... having a crank no start issue .. my fuel pump is good but curious to know if while cranking the motor is it normal for the check engine light to be on ?? If not does anyone know what that may mean ... I never noticed it before I know but I also never paid attention... Also have noticed the truck seems to sound a little different like a winding noise when it's cranking but also never paid attention before cause it had always started

 

Have you hooked up an OBD2 scanner to check for any stored or pending trouble codes? If not, the codes should help to identify the issue. When I experienced that issue a while ago, it was a bad crank sensor and the code I pulled pointed to that being the issue.

 

I don't have a scanner at the moment ... But will definitely try that as soon as possible

 

Yes, after the engine starts and there are no codes then it will go out. If you have any it will stay on.

 

I'm only getting 1.6 volts to my injectors, is that low and if so what would be cause

 

They are available at WalMart.com for about $20 or less. Obtaining the code(s) tends to alleviate any guessing as to what the problem is..

 

You will only see voltage at the injectors for about 3 seconds after initial key on, and then if the PCM sees the engine turning. That said, injectors want 12 volts.

 

As I'm cranki g only getting 1.6, then does that mean pcm is not worki g

 

Does the fuel pump run while cranking?

 

The asd relay supplies positive power(battery +) to the coil,02 sensors and the injectors. You should have power there while cranking, If not the asd relay might be bad or not coming on.
