Cnote0ne Posted September 29, 2024 Report Posted September 29, 2024 Hi, I have a 350z DE that won't start after I replaced the engine harness. The car was running fine before the harness replacement. I replaced it due to a short in the throttle wires that would trigger the car to go into safe mode sometimes. I've checked all the connectors and everything is as it was before. It fires up for a quick second and dies. I've added fuel in the table with no change. Any help would be greatly appreciated. Thanks.

Vaughan Posted September 29, 2024 Report Posted September 29, 2024 Can you hear the fuel pump prime? Do you have any way of checking fuel pressure? Quote
Cnote0ne Posted September 29, 2024 Author Report Posted September 29, 2024 Yes, I hear it prime when I turn the ignition on. I also tested it and hear it run until I stopped it in "Fuel Pump Test". Quote
Adamw Posted September 29, 2024 Report Posted September 29, 2024 I just deleted your other post as it was the same info. MAP sensor is not working. AN Volt 8 is showing 0V. It should be AN Volt 9 unless you have wired an external one. Quote
Cnote0ne Posted September 30, 2024 Author Report Posted September 30, 2024 Yes, I'm using the Link 4 Bar MAP sensor on AN Volt 8. Should I switch to the internal AN Volt 9 instead? Quote
Adamw Posted September 30, 2024 Report Posted September 30, 2024 You can use the external one, but you either have a wiring issue, sensor issue, or it isn't plugged in. So correct that and it will likely start. Quote
Cnote0ne Posted September 30, 2024 Author Report Posted September 30, 2024 I checked the connector and the line, they seem ok. Is there any way to test the sensor? Any other settings beside turning the AN Volt 9 on I need to do to use the internal sensor? Quote
Cnote0ne Posted September 30, 2024 Author Report Posted September 30, 2024 Thanks Adamw. The car started once I changed to the internal MAP sensor. I appreciate all the help. Quote
