Cadillac Repair: 1988 Cadillac Eldorado no fuel, cadillac eldorado, carbon buildup

Question
I have a 1988 Cadillac Eldorado that starts and runs great until you turn it off and return to drive again won't start no fuel to the injectors. What could make this happen?  Also have one code B120 which I think has something to do with the twilight switch. Is it the switch or could it be shorted somewhere else?  Thanks, William

Answer
If you arent gettin any fuel system codes i would doubt that is your issue, but computers arent perfect. Check the resistance at each fuel injector, let me know what they are. Make sure the air filter isnt clogged. Remove the air cleaner assembly and check for carbon buildup on the throttle body, there is guaranteed to be a good amount and some carb cleaner is needed along with brush to remove this. DONT USE BRAKE PARTS CLEANER OR ANYTHING ELSE. Let me know what happens after this.
