[melmount]

I have the older snapon mt 2500 scanner. I want to checl my ipr duty cycle. I cant figure out how? I can go to data and get say 14 percent after where it sayd IPR% but i am not sure if thats duty cycle? Can someone help out?
thx

IPR duty cycle is usually displayed as a percentage. Not familiar with the snap on scanner, but sounds right.

When it comes to stuff like this, especially Diagnostic Codes, I Always turn to Google

Real quick, I don't know if this helps, but I found this -> http://www1.snapon.com/display/3871/...ser_Manual.pdf

If it's a different model, the procedure might be similar or keep "pokin' around" with results and see if there's a better one

Here's what my AE doc says about results.

"Set up AE to monitor ICP and IPR duty cycle and crank it over. When you first turn the key on, you should get 14% IPR, and when you crank it, ICP should come up to 500 psi plus and IPR should be probably no higher than 25% or so. If IPR goes above 35% then you may have Injector o-ring leakage. That would explain the long crank times. You may also want to check cranking RPM, which should be a minimum of 100."

thanks i have been googling it. When the motor is first fired in the morning its about 700 psi and the motor is quit. As it warms its louder. Even at 600 psi its quiet. At aout 550 its sarting to tick and ticking good at 465 psi at normal operating temp. 550 to 600 is ideal from a good aftermarket pump. One from beans will shoot for 600 psi at idle. Its looking like a better pump will help me.
