Car won't start after driving, or in the morning

Asked by Jul 30, 2017 at 09:16 PM about the 1989 Buick Riviera STD Coupe

Question type: Maintenance & Repair

My 1989 riviera is having starting problems. In the morning, it won't start up
right away, I have to cycle the key in order to get it to start. After driving, I
have to wait for it to cool down or something in order for it to start, I pop the
hood, and have noticed that it helps. I just got a tune up, new fuel filter, new
fuel pump, new alternator, new ignition coil pack, new ignition module, fuel
injectors, oil/trans change, and a new battery within the last two weeks. I
haven't started the car in the morning yet because I just got the fuel injectors
in today. I tried starting it again after driving it once I picked it up from the
shop, and it just cranks and cranks. Once I pop the hood, the car starts
within five minutes. 10-15 minutes max with the hood popped open. I don't
think it's the crank shaft because when it does start, it's always consistent in
timing. Starts right up like a brand new car, there's only 122k miles on it. The
engine is a gm 3800 3.8L Series 1. I also smell lots of gas, the car is running
rich, I have bad gas mileage, and it's getting worse. Idle is usually high in
RPM's upon starting, but not once running. Anyone know what could be
happening?
