I have a 1997 old mobile auroa my car wont start I have a new fuel pump new censors and it still won't start whats the problem I have a new battery in it

If you have checked fuel pressure with a gauge and the pressure is normal, are you getting spark to the plugs ?

I'm assuming you replaced the fuel filter when you did the pump.
You'll have to try to figure out if you are loosing fuel to the injectors or spark to the plugs to proceed.
Its possible something is failing inside the distributor among other things.
I'm also assuming you have checked the computer for trouble codes.

Definitley NOT an O2 sensor(they don't even do anything for the startup).What happens if you shoot some starting fluid in it?

It sounds like a coil problem or its vapor locking when it quits again pour cold water on the fuel line and the fuel pump to cool both if your car starts you have found the problem if it won't start try replacing the coil

check fuel pump fuse and relay also the fuel injection fuse and ecu fuse, if they are ok remove the back seat and you will see a cover remove the cover and check for voltage at the pump plug and ground, you hear the pump work if not need new pump

Fuel Pump or starter. Since you say it's turning over but won't start I'd say it's your fuel pump. You'll probably have to drop your gas tank to fix this problem as your fuel pump is in the tank. You might be able to just loosen the straps and lower your tank a little to access it without removing the whole tank. Check around to local junk yards for this part and you'll probably find it for half the price as new. Make sure you can get your money back if the used pump doesn't work before you pay for it though. Don't forget to run fuel system cleaner (2 bottles to a full tank) once a month.

Your problem may be one of the following:
First check or just replace the fuel filter. Usually located under the car in front of the rear axle, drivers side.
Next, the fuel pump may be worn out. Usually they get loud or stop working (running).
Next, check the fuel pressure regulator. Usually located on the front fuel rail, drivers side.
Is the vacuum line attached? Not leaking or rotted?
Also, do you smell a strong fuel odor when it won't start? May be one or more stuck-open injectors, or the coil pack is bad.
Checking these in the order listed will more than likely fix your problem.
The clicking noise indicates the battery can no longer run the starter, which also means the fuel pump won't run either.
It could be a fuel issue. How old is the fuel filter? Can you hear the pump run for a few seconds when you turn the key on? Try turning the key to ON without trying to start engine three times waiting for the pump to stop running each time. Then try to start the engine. If it starts, Its a form of Vapor lock caused by the extreme heat we have had lately, and a weak fuel pump.

If none of this works, try a new fuel filter first. From there have someone check the fuel pressure regulator and then the pump. If you are in need of a new pump, take my word for it and spend the money to get one from a Dealer, and not from your favorite parts store. Most parts store parts are made in China and they are JUNK.

When you changed your fuel pump did you also change the fuel filter? If not, that would be the next logical step. While you have it disconnected you can also check to make sure the fuel pump is pumping the fuel.

Now you have a good battery & a starter that turns over the motor

Have you cycled the key on & off with a fuel pressure gauge on the
fuel rail?

Do you have a fuel filter that isn't over 3 or 4 years old?

Have you checked for spark while cranking ? Use an old plug on the wires,
if you have ignition wires,don't ground the wire without resistance

If you removed the ducting & MAF Sensor it won't start

Tell us what you checked & exactly how that was done.

No safety if that is what you meant. Car not starting likely a bad fuel pump, common on Bravada / S10s. Try "thepartsladi" on eBay for low cost OEM part.
