Intake backfire before cranking.
I have the mspnp9495 and whenever i turn the key to the on position before a cold or warm (not hot) start, there is an intake backfire. It seems to be exactly 2 seconds after the key is turned to the on position and will occur before cranking. If i don't allow 2 seconds between key on and cranking, it will usually backfire while cranking. I have recently changed from 460cc injectors to 550cc injectors and the problem occurred with both sets of injectors. So i know it's not the injectors Any idea what may be causing this?
Thanks in advance, Wes Wingham I can attach my msq later when i get home. |
Go into the cranking settings and look at the prime settings. Disable it.

I will try that when i get home. Now, when it says priming pulse, is it talking about fuel or spark?
