should check the oil pressure switch first if that does not fix the problem than connect a oil pressure tool to see if u really dont have oil pressure. if got good oil pressure around 35 to 65 psi any thing lower replace oil pump.
I would try the cheapest route first Go but a oil pressure sender to see if that fixes the problem
Do a pressure test. We need to know what engine you have to give you the pressure specifications.
Fuel pump pressure (Maximum) 75 psi
That would be best left to a repair shop. You will need a pressure bleeder.
Bad oil pressure switch - $10 Clogged intake screen - $?? Bad oil pump - $1000 Worn bearings in engine - $a lot
Need oil change or oil pump weak or oil pressure sending unit not reading properly.
you will need a fuel pressure and flow gauge and then check actual meaured to specs.
No you don't need a tank to simply pump water from a lake. You would only need a tank if your using a pressure switch to turn the pump on and off.
That is a sign of a bad fuel pump
You just need to adjust the pressure switch on the pump to your desired pressure...typically around 50 psi. Sometimes the springs in the pressure switch get old, and just need tightening.
The 2000 GMC Yukon Denali fuel pressure regulator is located on the back of the fuel injector pump. The fuel injector pump is located on the top of the engine.
you could but ,it would either burn out the wiring due the high pressure need in the fuel system cuz there is nothing to cool same with the pump
You will need a fuel pressure gauge.
