Engine/Transmission (1998.5 - 2002) VP44 Question

[HookMeUp]

Today the weather turned cooler, about 59° I have noticed that the injector pump is louder. I had this replaced under warranty about a month ago, running fine untill today's question. Is it possible that the intake air is cold enough that the pump is going into full advance, hence the noise. Or is the pump going out again.



Thanks

Do you have a Fuel Pressure gauge ??



the ECM advances the Engine timimg when its below operating tempature.



I Cant hear my Injecton pump running ?
