Cadillac: 1995 Cadillac 4.9 engine Injector Timing, injector pulse, scan tool

Question
How do you check fuel injector timing without a scan tool?
Can you download using dash display? We tried, does not work.  

Answer
I assume your trying to see what your INJECTOR PULSE WIDTH is ?.

you can use the display to individually fire each injector to see if it is operating ok. But you cannot recalculate the amount of fuel flow at a specific time as this is performed by the computer based on various inputs.

I can provide you with the pictures and procedures on how to test the injectors via the display panel. Contact me at: onlineautohelp@msn.com
