I have a 2003 Deville...battery is under rear seat ...pull seat up and out to raise....battery itself is very easy to change out.

there's a shraeder valve to easily de-pressurize the fuel system before working on removing the injector...



you need to remove that plastic "beauty plate" to see the intake plenum/ manifold

he shows you how to unplug the electrical connector from that fuel injector

from there, someone else maybe chime in on how to disconnect the hose from the injector if you have a similar setup as that youtube link

PS: make sure you lube the o-ring of the injector before installing How to change fuel injectors

Well, I don't think so. The pressure sensor will throw its own code (0450, 0451, 0452, 0453, or 0454). And likewise, the fuel level sender or sensor could also throw its own codes (P0460-P0464).

I'm not sure the level sensor and the pressure sensor are linked together. They are separate on a 2005 buick century, the pressure sensor being at the top of the tank located on the fuel pump module, but Cadillac: anything is possible.

Since you replaced the purge solenoid, there may be a problem in the circuit. The purge should have battery voltage to it with the key on. The ECM will ground the circuit internally when the purge is wanted. One symptom of a purge valve that isn't working or stuck closed can be a whooshing sound when the fuel tank cap is opened, indicating excessive pressure in the tank.
A shop's scan tool could be used to command the purge valve on to check it.

on most vehicles, the pcv valve comes from the valve cover via a hose from vacuum. the pcv valve should be at the valve cover side. Good-Day! it is used to recycle the oil fumes, and burn them up.

This will violate local emission laws to install and older engine model year.

Bad relay could be drawing excess amps. Bad starter can do this as well.

MMY 2003 DTS HAD SAME PROBLEM. REPLACED FRONT COIL PACK AND FIXED THE PROBLEM. LATER #3 CYLINDER STARTED MISSING, REPLACED REAR COIL PACK AND SOLVED PROBLEM HOPE THE HELPS

Northstar motor?? If so it's on the firewall, and the only,,,,, I say ONLY way to get it out,,,,,,, is to unbolt the cradle and let the back of the engine down.
