The 1974 Chevy truck has a mechanical fuel pump with a built in pressure regulator.
21
It controls / regulates the fuel pressure.
That depends on what engine it has.
I need to know why do i need to crank my chevy truck to start ?
Oil pump is bad.It is located behind the lower timing gear on the crankshaft
It is in the throttle body.
it can have spark & fuel pressure ;But if the brains bad the injectors won't open up, To test it spray alittle start fluid and if it starts its the brain.....hope this helps.......
Engine oil pressure, cooling system pressure, ac pressure, fuel pressure?
you should try to poo in it
The fuel pump is kaput.
Need engine size.
