Question about 1993 Oldsmobile Bravada

1 Answer

My 93 bravada wont start since i replaced sending unit

I have a 93 olds bravada that ran before, but leaked gas due to a rusted sending unit. i replaced it and also the car battery because it too was bad. i poured a few gallons into the tank and it wont start. car turns over just fine but will just not start. i dont really know how to check the fuel pump, i just assume its working because when i turn the car on it registers the correct fuel level and i know its a mechanism on the pump that reads that, so i just assume its fine. i dont know what could have happened between the time it ran fine, and the time i put a new sending unit on.

    the sending unit with wires are new, so im hoping thats not the problem. i tried turning the car on to hear the fuel pump without a gas tank or hoses attached, and theres nothing. the fuel pump doesnt hum or do anything. would that be enough to mean that the fuel pump doesnt work?

    alright, i turned the car on and let it sit for a bit while on, no action from the pump. i tried starting it too to see if the pump would respond- nope. is there another way i can check to see if the pump is alright? or shouldnt it have responded by now.

    well i gave up for a while and now have resumed this project. The fuel pump has no power. The sending unit and fuel pump relay all have power... so im replacing the pump... ill report back eventually

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.

What would cause the gas gage not to work in a 93 bronco?


Nine times out of ten, rust in the gas tank has caused the sending unit to rust. WD-40 (large amounts of it), sprayed into the sending unit, usually fixes that.
Also, if I'm not mistaken, the 93 Bronco has a "Low Fuel Light" circuit right next to the gas gauge. If that circuit fails, the gas gauge will also fail.
Start by seeing if you have voltage to the gas gauge circuit with the ignition key on. If you do not, replace or clean the sending unit. If you do, replace the Low Fuel Light circuit plug-in.

My olds ran out of gas .I went and got gas and put it in.now my car won't start and it doesn't sound like my fuel pump is working. What should I do?oh when it ran out of gas it was below 20 degrees...


Your problem could be due to a clogged or gummed up fuel filter, usually when a car is run out of gas the manufacturer recommends changing the fuel filter due to the amount of sediment that inherently sits on the bottom of gas tanks and gets sucked into the system... especially one as old as this. Additionally you may have tank condensation that froze inside of your pump and it will need to be replaced. However this is a worst case scenario, always check the least expensive solution first.

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
