I am having a problem with my Chevy Tahoe when I
start the truck no it's oil pressure stays at 20 but
when I get on the pedal it goes down to zero and
when I gradually gain speed it goes up to 40 does
that mean my fuel pump is going bad
Can someone please help
When was your last oil change? EIther your oil is low, or there is a blockage. Either the strainer or the filter is really old. this has nothing to do with your fuel pump. Driveing it like this will kill the motor
Going to save you a lot of headach. 1) change to thicker oil and new oil filter. See if the helps. 2) since you are getting oil pressure when driving fast, it's not the oil pump. Change out the oils sending unit. See if this helps. 3) oil pan area. Change or clean out oil pick up screen. See if this helps. 4) check your oil guage cluster to see if it's working correctly. See if this helps. 5) here's the bad news of all else fails than it's your worn out cam bearings. Meaning engine rebuild. If you know somebody you can get it done cheap like I did or you can spend more than the price of your cars worth. That's all to it. I went through all of them and finally got it fixed. 2005 Tahoe with 200,000 miles on it.
