They come out the top of the throttle body. Clean area thoroughly before replacing the injectors to avoid any dirt getting in to the system.

It is under the air cap and behind the fuel injectors.

Could be poor or no fuel pressure due to a bad fuel pump. Also check the fuses.

it could be your fuel pump relay. it should be located under the hood in a box marked fuses or relays.

there were no 5.3 in production in 1988; but on a small block Chevy in 1988 you should have 22-25 psi

the fuel injectors are located on the top of the throttle body, to get at them take off the air filter assembly, once you remove that you will see the two injectors on the top.

Yes, But it won't look right. 1988 is when chevy redesigned the body / changed it.

User Avatar

there's four injectors you have two primary and two secondary , the primary injectors are on the top of engine very visible but the secondary you would have to remove upper intake plenum to get to them ...

User Avatar

Probably because the o-ring seals on the injectors are 23 years old...

Remove the wiring harness from your 1988 Chevy Cavalier fuel pump. Remove the fuel lines from the fuel pump. Remove the fuel pump retaining bolts. Reverse the process to install the new fuel pump.

Home Lines ended in 1988.

Yes and it is a TBI / Throttle body injection fuel system. The item on the top of the engine that looks like a carburetor is called a throttle body and it has 2 injectors in the center of it.
