It could be the fuel pressure regulator, but that can be determined by testing the actual fuel pressure in the fuel feeder rail. But first, have you changed the fuel filter? The fuel filter usually is clogged with debris whenever a fuel pump fails, so be sure to change that first.

Will not start. no gas getting to carburater.put gas in by hand will start?


First, I would like to know where on earth did you find a 1999 Chevrolet Suburban that is equipped with a carburetor??? I would like to see that one!

You need to check the fuel pressure at the fuel pressure test port. If the fuel pressure is low or there is no fuel pressure at all, then you need to iagnose your fuel delivery system - fuel pump, fuel pump relay, fuel pump circuits, fuel filter and the fuel pump relay circuits to the Powertrain Control Module (PCM)

If the fuel pressure is OK then you need to diagnose your electronic fuel injection system - this includes first scanning the PCM for fault codes to determine if the problem is being caused by one of the sensors or the antitheft system.

The MOST LIKELY cause of your problem is a bad fuel pump, but I would not run out and buy a fuel pump and pull the tank out of a Suburban without checking the other things first.

ok here we go, hook up a feul pressure guage that can be read from inside the car, and check fuel pressure while driving, if the pressure stays fairly constant then the best bet is to hook up a real time scanner with snapshot capabilities ( like snap on or bdm pro) and take it for a drive again, ti could be a sensor reading out of range but not enough to set a code

Your problem is most likely a sensor problem. Did you get a check engine light? It could also be a fuel pump. These vehicles are verry sensitive to even slightly low fuel pressure. Once the pump starts to get tired they just start running crappy followed by stalling and hard starting. Id start testing cheap stuff first. Like the O2 sensor. If it has been a while or never changed then it needs changed. Should be changed every other year or so to keep it working in tip top shape. cheap O2 sensors may have to be replaced more often like once every year. Next I would look at the MAF sensor. These often get a bit dirty inside and affects the ability for it to detect the proper amount of air. Clean it with a MAF safe cleaner and it just might do the trick.

Suburban low pressure from fuel pump


Try checking the fuel filter and then the pressure regulator on the rail. If the pressure regulator is bad it will not let the pump push enough pressure. And if the filter is clogged then it will also not let the engine get enought pressure. I have seen pumps starter going out by losing pressure. I have also seen aftermarket pumps quit after about a week unles you did not change the whole assembly.
