What does the fuel pump pressure have to be start on a 2001 s10 2.2 i got 53?

A fuel pressure of 53 PSI is generally too low to start a 2001 S10 2.2L engine. The correct fuel pressure for that engine should be between 58 and 62 PSI. While some slight variation is acceptable, 53 PSI is significantly below the minimum. Low fuel pressure can prevent the engine from starting or running properly.

Possible causes for low fuel pressure include:

* Faulty fuel pump: This is the most common culprit.

* Clogged fuel filter: Restricted fuel flow will lower pressure.

* Leaking fuel injectors: Leaks in the fuel injectors can reduce system pressure.

* Problems with the fuel pressure regulator: This component regulates pressure within the fuel system.

* Weak fuel pump relay: The relay might not be supplying enough power to the pump.

You should investigate these potential issues to determine the cause of the low fuel pressure. A mechanic with diagnostic tools can help pinpoint the problem quickly and efficiently. Attempting to diagnose and repair fuel system issues without the proper knowledge and tools can be dangerous due to the flammability of gasoline.
