Insufficient fuel pressure is most likely the result of a faulty fuel pump leaking fuel lines a clogged fuel filter or clogged injectors , also if you are not getting any fuel at all check your fuses and look for a short in the one for the fuel pump

i cant say 100 % but if i remember that model may have a fuel cutoff safety feature there should be a yellow button in the glove box or a yellow handle behind the fabric on the passengers side rear trunk..is so push the button or pull the lever to allow the flow of fuel again
also when you turn the key to the on position do you hear a slight humming noise if so the fuel pump is working / but may not be supplying sufficient pressure which will disallow your vehicle to start

if no sound is heard check the fuses 1st then test for power to the fuel pump with a test light and note the ignition system also works correct ?

If it will run on carb cleaner only, you are low on fuel pressure or the injectors are not opening.

1994 olds bravada trys to turn over but wont start


First check the spark up at the engine. Also turn the key to the on position with out turning it over and listen and see if the fuel pump primes. You should hear it hum. Thats where I would start anyway. If you don't hear it prime, then the fuel pump is out. If it is running and you are getting spark, then you may have to hook up a fuel pressure gauge to it and make sure you are getting enough pressure.

1998 olds Bravada, runs great in the driveway, once in gear, i give it gas and it quits, only happens in cold weather


Bad TPS will give you a SES light. Possible low fuel pressure from bad fuel pump. Put a fuel pressure gauge on the service port close to the firewall, should stay above 50 psi when juicing the gas. Only use OEM parts on a Bravada! Try "thepartsladi" store on eBay.
