The only way to fix is to install a new oil pump but since it does start to pump after two minutes there is something you can try no promises

how many miles? prob could be just the oil pressure sensor?

F_O_R answered 6 years ago

This could be a false low due to a bad oil pressure sensor or a clogged screen at the sensor. Then again your engine may be worn out.

I have a 2004 Chevy Silverado extended cab, 4.8 liter. I have had multiple issues with this vehicle, but the one I can't seem to solve is this: if I leave the truck sitting for a day, when I get in and start driving, about 5 miles down the road, it acts like it is being starved of fuel. The engine light starts blinking and there is no power even when i step on the gas fully. After a minute or two, it goes away and runs fine unless I let it sit for a couple days. I just replaced my fuel lines because they were rusted out but that didn't solve the problem. Any ideas anyone? 6 Answers

Engine light is always on and blinks on and off when problem occurs.
