I am having a problem with my 2015 5.7 fuel injected engine. It stalled while under way and would not restart. I have had mechanic try and diagnose issue and there appears to be something wrong with ECM. I have power into ECM but no power to fuel injectors. After 4 weeks of back and forth with manufacturer I finally got them to send me new ECM. I was able to get engine to start with new ECM but it stalled after about 1 minute. It does restart immediately but does the same think. Runs for about 30seconds to 1 minute and then stalls. I have checked fuel rail and I have 55psi. I replaced MAP sensor and it did not make difference. Cant seem to figure out what is causing issue. Mechanic thought ECM or harness issue. The manufacturer also sent new coil which I installed. Going to hook up Diacom to read computer and see if any trouble codes. Mechanic cleared them all out after installing new ECM.
I am stumped hoping someone on this forum has an idea.
Thanks
Matt
