I don't think so. The protune is more a middleman and if the main man is communicating, the pro forced a spark, then the spark had to begin at the black box, flip-flop to a spark. So it was more like saying, pro acts the crank sensor, this is now input. The black box sends out an output and it sparks.I get no spark and then I try through ProTune and get spark is that tell me that ECM is bad
Didn't get a chance to check the fuel I'd like to have another set of hands with the fuel tankThen if you disconnect the fuel hose will all the gas drain from the tank? If there isn't a check valve, when disconnecting the hose gas would pour out for a moment under 60 psi. Help me out here.
I have to ask a stupid question where is the 12 v power relay located. I need to testThe only time you will get power to the coil is when:
1. The RUN button is pressed. For about 2-3 seconds, the fuel pump will charge and power to the coil, O2 heaters. Then relay turns OFF.
2. Press the START button. 12v power relay kicks in and engine cranks.
3. And while running.
The 12v power feed relay should work with normal operation and Protune2 the same way. If you have disconnected the battery, you MUST do the ECM reset procedure after reconnecting the battery. The battery POSITIVE lead is FIRST ON and LAST OFF.
I always follow battery procedure on batt. Thanks for your replyI have to ask a stupid question where is the 12 v power relay located. I need to test
hi guys, i was having the exact same problems with my 2008 mastiff.after reading these posts i knew what to do.purchased a new ecm from s&s,plugged it in,and runs like a champ.i would like to thank everyone who participated in this post.yall got me back on the road.thanksUpdate........ Checked relays they were ok..........well my new to me used ECM came in today. Took me about 30 min. To get it installed. I opened protune and no DT's yea first good check. check engine light is off. Reached up to start button and wow the sweet sound of that 117ci. So all I can say it had to be the ECM the whole time as I suspected as the poss culprit. Now I just have to clean her up and ride on..........
I want to personally thank each and every member who left a post on suggestions on what to do.
THANKS GUYS!!!
