Question about 1983 Cadillac Eldorado
I know there is a fuel regulator diagram inside of the throttle body fuel injected carb. i was wondering if there is any other regulator by the gas tank or on the tank itself, on the 83 cad. eldorado birratz. i am not getting enough fuel to my injectors. have replaced fuel pump, filter, and rebuilt the injectors. the guy who rebuilt them said they were not in that bad of shape, so i dont think the problem was in there. car wont start unless i use carb starting fluid, and it wont stay on unless i keep spraying alittle at a time. i try to accerlate, and i t boggs down like its flooding, but it i spray fluid while accerating it seem to run fine.

The solution is more than likely a new blower motor. Replacing this blower motor is no small task. I am in the process of doing it, but there is so little wiggle room that I suspect that if a cadillac mechanic does this job, they will jack up the engine/transaxle to make room. The motor itself is not cheap either, a replacement Delco is well over $200. I will let you know if my new motor install works.

first thing to do is check the fuel flow - clean the in-line as you did and change the canister filter. Also check for any blockages / kinks in the fuel line etc. Vent opened on tank if applicable
Would the engine rev up when out of gear ?
Also check your ignition switch,check spark, fuel pump, voltage regulator,pick up coil in dist,
Let me know for further clarification.

You just need to go through a simple Idle Relearn Process.
The Idle Speed Control motor will cause the accelerator pedal to tap and the car will surge back and forth, actually acting like there is a lack of power during intial startup.
Whenever a battery is changed, went dead or the ECM computer is replaced.
In order to make the engine run normal again, you need to take the car through a relearn process. Otherwise the idle could be very slow or have a 30mph idle.
To enable it to relearn, here's what to do.
1) Disconnect the battery cable for 15 minutes, before hooking it back up.
2) (KOEO) Turn the Key On with Engine Off, just so the electronics are on, but without starting the engine and turn the climate control panel to off.
3) Push the off and warmer buttons on the climate control panel at the same time and hold for up to 5 seconds for the computer to go into diagnostics.
On the fuel panel screen it will display 888 then E52 and then 70.
When it gets to 7.0 shut off the key for 1 minute.
4) Repeat step 3, two more times.
5) Start the engine without pushing on the accelerator pedal and let it run for 18 minutes with the climate control panel off.
6) After 18 minutes put your foot on the brake and shift into drive and wait 1 minute.
7) Then turn on the a/c by pushing the auto button. It needs to be warmer than 60 degrees F so the compressor can engage. Wait 1 more minute.
8) Put the shifter back in park and turn the key off.
9) Wait 1 minute
10) Idle relearn is now complete and the engine should start and run correctly.
