My g35 won’t go over 4K rpm After new muffler installation, what is the issue?
Okay I was driving and I tried to go over 4K rpm in my 6mt g35 de coupe and it would like sputter. I then drive it back slow to my house wher I proceed to get this clip of me giving it gas, this is in neutral. Can this be my fuel pump? It was running perfectly yesterday, I did get a muffler installed yesterday as well but what would that have to do with this issue? Any help would be appreciated.

well now it won’t start it just cranks as I was about to get a clip with no music. Well I showed me pressing the gas and the rpms won’t move. It moves up maybe 100 rpm then doesn’t respond. What the f can I do about this? If there was packing it wouldn’t sound good as it did yesterday as I’m sure the engine would overheat. I had the muffler installed by a shop

If it cranks but won't catch there's a good chance the crank position sensor died, typically this would also have a service engine light and a DTC attached but not always.
It could also be causing the throttle problem, it's near exhaust components (sort of) so I would get the vehicle up on jack stands and start looking for melted or damaged wire, harnesses, etc.

Did you run out of fuel? You can't always rely on the gauge on the dash so I would add 1 gallon of fresh fuel just to verify the tank isn't on empty. Next up, what is your security indicator doing when you put the key in the ignition and crank? Unfortunately you can't check fuel PRESSURE without buying and installing a sandwich adapter for the fuel damper, Z1 motorsports sells one for cheap though it's like $25 and you also need to buy a schrader valve or fuel pressure gauge for it.

Thanks but I went ahead and bought the fuel pump anyway and installed it, still no luck. Is it my engine? It turns on now but it stays on for like 7 seconds and then dies again. I am becoming hopeless like what the he’ll else could it be?
