Hello my name is ***** ***** am I speaking with? Have you done any troubleshooting on your own yet? Being a fuel injected engine there is a 50/50 chance that the engine will have to get hooked up to a scan tool How is it I can be of help to you, what kinds of questions did you have for me?

This is Greg.
I am getting my boat ready from winter storage and all is good till I tried starting the engine. It is a 2006 350 mag mpi. It turns over just fine but will not start. I can hear the fuel pump activating when the key switch is turn on, I verified that i have gas to the filter, I have tried starting with the hand throttle position in 1/4 and in full throttle, the flame arrestor has been cleaned and dried, also tried starting with arrestor removed.

Hi Greg,Have you checked spark or fuel pressure, or checked to see if it will start on starting fluid?
Customer: replied 1 year ago.
I have not done any of those. I can get starting fluid, and a pressure gauge. What do you recommend as the proper way of checking for spark? Where do I install the pressure gauge?
