Takes 30 seconds or more to start. Starts immediately when I pour gas down the throat. Restarts immediately - no problem. Runs smooth. Check Engine light intermittent.

Could it be an electrical problem? What do these codes mean?

The codes are:

E20 - Open Fuel (http://www.cadillacforums.com/forums/#) Pump Circut Feedback Signal

E22 - Open TPS Signal

E25 - EST Circut Problem in Bypass Mode

E30 - ISC RPM Out Of Range

E52 - PCM Memory Reset (See Note)

Someone had taped over the Check Engine light. I didn't notice it until last night.

I bought a new fuel pump, but this beast has a sway bar? directly under the rear axle and I can't find a place to put my jack stands.

Someone said replacing the fuel pump is a pain. What kind of pain?

:confused:
