The fuel pump is inside that odd shaped box held together with about 6 philips screws. If you open that up be careful as the o-ring for the ld will quickly lose its shape. Pull the leads going into the box and see if you have voltage to the pump first.

Or just pay a Merc tech to scan for trouble codes. Will save a lot of guessing which is what we are all doing trying to help you. We've all been there. Good luck

Time to find a merc manual online #16 and start thru the flow charts. It is a royal pain but will work to get u going again. The merc tech will guess and trial and error until he stumbles onto something. The flow charts will nail it down.

Unfortunately when attempting to repair problems like this, you need a test light or multimeter. A fuel psi gauge to mount in the fuel rail is also handy. These are tools available at any auto parts store. I know everyone wants that simple fix of it being "just a fuse" or a "tripped breaker" , but sometimes it ain't that easy.

If your willing to attempt to diagnose the problem step by step with a few tools, I think your problem can be found. Or, like you said , just bring it in to the dealer and let them work the test light, meters, etc and give ya the bill. Sometimes it's better letting someone else track down the problem . A good tech might find your issue in an hour, where you might have days and days trying to figure it out.

Yes a good tech might find it in an hour but a normal tech might takes three days and are highly incentivized to do so. Techs also love to guess and swap parts until the stumble upon something. Must be this, must be that. The flow charts will take you right to the problem, no guessing.

I have used a volt meter the entire time from checking the starter to key switch. Everything I have tested has 12.5-13 Volts. So I'm left to believe the fuel is not getting past the injectors which is why was looking for any additional fuses or breakers that maybe I missed. Again thanks everyone. I feel like I have chased every wire on the ignition and fuel delivery wiring diagram. Good experience and learned a lot but maybe a little beyond my technical reach. Not to mention I hate wiring haha

x2

open up yjr blavk metal box where the ecm is at,its about 8''x3'' once open their are 2 fuse leads in their,one is for the ecm and the other is for the fuel pump..might have a blown fuse in their or one of the releys are bad..

All great advice.

If you cranked a bunch of times, yes, your plugs would smell like fuel.

Air/fuel/spark. You have air and spark.

Spray starting fluid in the arrestor while cranking. One time...at band camp, I changed my water separators and one motor would not start until I helped it along with starter fluid.
