Question about 1996 Cadillac Seville CA Value

1 Answer

1996 Seville died and won't start

Driving last night and she just died. Fuel guage did not show empty before (about 1/8 tank) but when I coasted to a stop and tried to restart it went to E. Dash panel says Service Emissions System, Service Electrical System, Service Fuel System. I put a gallon of gas in the tank and tried to start and it ran for a second or two and died again. Put about 5 gallons more gas in but still not starting. I know it's getting spark because I removed a spark plug wire from the plug and saw spark when trying to start it. What can I do to get moving again?

    OK. I diagnosed down to the fuel pump and towed it in to a shop to have it replaced. They replaced the fuel pump and said the wiring was fried. They fixed that. It still wouldn't start for them. Did a compression test and found that spark plugs were in bad shape. Replaced those. Still nothing. Ignition Control Module was bad. Replaced that. Now, it starts and I can drive it; but, if it sits too long, the battery drains and has to be jumped to start. They said the battery was bad; but, I had it tested at Auto Zone and it passed. Still have Service Emissions System, Service Electrical System messages and the Service Engine Soon light is on steady. This morning it displayed a Service Idle Control System message. None of these messages occurred before the initial problem when it died while driving and the battery stayed charged the whole time I was dignosing the fuel pump problem over several days. Is there something with the PCM that needs to be reset or am I on the verge of a complete failure?

Try Spraying Some Throttle plate cleaner into the throttle bore & see if it tries to start?? If Yes Most likely fuel pump died.

Starts and dies right away, intermittent fuel guage


If initial indications sound like a buoy gasoline and extenders and gasoline injection system in the compartments, the problem is in the power feeder wires or in the Bawa-jee or in the combustion chambers of electricity and gasoline. This prevented Mator that it does not appear any kind of Leak of oil and water.
So observed in the case of operating the initial car exhaust fumes if the color was black injection system maintenance problem but if the sky was the color of this is evidence that the oil spill to the combustion chambers.

Just filled the gas tank in my 2006 f-350 turbo diesel super duty (6.0), started the truck and the guage showed a full tank. Drove down the road about 1/10 of a mile and the guage dropped to dead empty...


A loose connection on the sending unit could cause the problem but also moisture in the tank in cold weather could also be a factor in which i would add fuel line antifreeze to a full tank of fuel..........Hope this helps you out.

It defanetly sounds like a sending unit and the fuel tank needs to be removed in order to replace it and it will most likely come with a new fuel pump too.They come as a unit and there not cheap. Sorry.

the gas gauge contacts get corroded by the chemicals in your gasoline over time, the only way to fix that is to replace the fuel sender unit...unfortunately the sender unit is usually incorporated into the fuel pump. fuel delivery problems like you describe could be clogged or dirty fuel injectors...if it's dying out on you as you drive it probably is indeed the fuel pump...usually an expensive fix. try an auto wrecker to find one for about 100 bucks.

Car bogs down when given gas.


Hi there,
This problem is most commonly caused by a weak fuel pump. It will need to be checked with a fuel pressure guage. If you can obtain a fuel pressure guage you will need to observe the fuel pressure while accellerating to see if it drops out.
good luck
