Customer Question

I have an 07 g35 80000 miles , I changed the air filter and ran some sea foam through the intake to clean out carbon. Ran Wonderful, then it started to spudder then stall. Roma would drop to 1000 then die. I thought bad gas. So I filled with premium like always then drive home and left run at idle . Ran for 2 hours then died wouldn't start back up. Turns over no running. Replaced fuel pump still no joy. New air filter and cleaned mass air flow . No luck. Unhooked mafs still nothing what am I missing??

Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
In order for the engine to start and run you need injector pulse, good spark, proper fuel pressure and compression. Before you replace anything else let check and see which one of these you are lacking, check spark, injector pulse and fuel pressure and post back and we can work from there to determine the cause.
