Chicken vs Egg Symptoms from 2005 Suburban 5.3 FlexFuel
The oil pressure thing is quite normal for the LS based 5.3L LM7 which is in her Suburban. This stems from the pump's pressure spring wearing out and/or the plunger it backs getting sticky in its bore. Best solution for this is to get a new oil pump and install it. While the oil pul isn't technically in the pan, I'm pretty sure you have to take the pan off in order to get to the bolt which holds the pickup tube on (I've only ever removed them with the engine out of the vehicle and oil pan off). As for the issues, check to make sure the battery is fully charged (at least 13+ VDC with engine off) and the alternator is charging correctly (~14.1 VDC running). If either of these are low, it could be your issue. The fuel pressure should be ~58psi. If the fuel pressure is low, it may be causing the noise you are (or were) hearing. Knock doesn't usually show itself unless there is a torque demand put on the engine, like it being in gear. Usually you wouldn't hear it unless you actually step on

2003 Hyundai Santa Fe will start then die. Then it will not start. After pumping the accelerator or holding on the floor and returning later it will start. Nothing codes out. This happens probably 15% of the time. Any ideas?

A friend has an older Miata that was improperly stored for at least three years. Most of the time, it was not garaged. The gas is old, the battery is dead, it has not been started. It was probably parked without an oil change. He is looking to do the minimum to get this sellable, so the primary concern is the initial startup and the brakes. What would be recommended , especially regarding that first engine startup?

I’ve asked a few mechanics and DIYers this question and so far no consensus. Let’s say you’re 1000 miles away from next SCHEDULED oil change, and you’re about to leave on a 2000 mile road trip. Would you choose to change your oil 1000 miles early before the trip, or 1000 miles late after the trip?
