I'm guessing from your short statement that you are not getting fuel. Your '93 would have either the 2.8 or the 4.3 v6. If your not getting fuel, check the fuel pump relay, look for a blown fuse. Disconnect the oil pressure sensor and jump across the connector terminals and try to start the engine. If the oil pressure sensor is bad, it will shut the fuel pump off.

No start on 93 olds bravada without starter fluid , i did a fuel pressure test idle was good but when i switched ignition off the presure went straight to 10 psi from about 60 psi , i suspect a bad c


Internal pressure regulator on the fuel pump should hold for about a minute but some pressure loss is normal. However, on initial start-up, the pressure must be at operating pressure or the system wont work. I suspect the fuel pump is failing, it is an all too common problem for GM trucks and SUVs with mpfi fuel injection.
IACs do not go out very often, usually there is a problem with vacuum leaks, dirty throttle assemblies.

When the antitheft system fails on these vehicles, it can turn off the fuel injectors to prevent theft. This may be your issue and this link talks all about the problem.

Truck wont start unless i pour gas into injectors.


It sounds like the electric fuel pump has failed. The electric fuel pump is located inside the fuel tank, you must remove the tank to service the fuel pump.

Replaced fuel pump & still car wont start on 97 olds 88


The fuel pump most likely is not the problem,replace the crankshaft sensor,it tells the computer to pulse the injectors,and the spark.

Fuel problem


Check your fuel pressure at the Shredder valve, you should have 60PSI to 65PSI. If you have less then that or more then that your going to have problems with your fuel injection system. The other thing to is to check your fuel pressure regulator. Hook up the fuel pressure gauge and turn the ignition switch to the run position to activate the fuel pump. Once the pump stops pressurizing the fuel line wait and see if your losing the fuel pressure excessively. If you are then your may have a bad regulator and it's leaking internally. The other thing to is may be a bad fuel pump, The good news is the fuel pump in the sending unit in your bravada can be replaced rather then the whole unit. If it is the fuel pump, Buy a heavy duty pump to install to your sending unit. Don't have them sell you the whole unit, pump alone is around average $60.00 other then the whole unit for $230.00. Good luck and keep me posted, be glad to help

96 bravada replaced fuel still no start runs with starter fluid


If your getting gas and spark get an obd 2 scan tool and check your mass air flow sensor. I had the same problem. If your having a problem with this vehicle always check the computer first; it will save you tons of headaches later.

1999 oldsmobile bravada stalls out when driving and will not start at all times have had starter and alternator checked


If its a crank but no start, i would put money on it that it is your fuel pump, ive put two in my 1999 bravada, they have updated fuel injectors too (recomended), i changed injectors all the way to the pump fully new fuel system and it runs just fine now. go to ur local junk yard and pay about 50 bucks for a used one and see it if doesnt help... i would recommend trying a used one befor u spend 300 on a new one. good luck
