2004 Buick Regal car started but would not move low oil pressure and power down lights came on

SOURCE: 1999 Buick regal Security light on. Won't start.

I had the same problem with my 95 Lesabre. The owners manual says to take the key out, and wait 3 minutes(until the light goes off). It should fire right up.

You have a problem in the fuel pump relay circuit for sure then. I'm betting the relay, but it could be that dropping resistor.

ur oil pump may be failin-there r sensors everywhere on new cars-keepin u from starting as safety measure-computer systems r complex n things dont always show on 1 scan-they kinda hav the mindset of a pc

Testimonial: "Thank you. I have spoken with 2 other mechanics who said the same thing regarding the oil pump. It's being looked at. So I'll post more once I know"

Sounds like you might have an oxygen sensor problem. Your catalytic converter(s) maybe defective or dirty. That in turn can dirty up the oxygen sensor. A defective oxygen sensor will send faulty info to the computer, interpreting the fumes as cold (even when the engine warms up). That causes the computer to adjust the fuel mixture to very rich, giving you poor gas mileage and the fuel smell. Hope it helps.

This one took me 30 mins to find, its at the back of the engine at the center of the firewall (below the windsheild ) . This is where the a/c lines go into the car ( evaporator) its hard to see if your tall . Remove the cap and attach your guage . Good luck.

Ps. Fix the leak first
