Fuel pressure gauges are often specific to vehicle. The car brand you own will often make the one most reliable for your vehicle. You can also try a NAPA brand one, as they often take great care in providing quality parts.
well the question is a bit vague but I'll try. Assuming that the battery isn't dead and the starter is cranking fine my first thought would be your fuel pump is shot Chevy fuel pumps are notorious for failure even with low miles I had to replace my brothers fuel pump on his 96 Chevy and it only had 58,000 miles on it. But to know for sure wether the pump is bad or not you will have to do a fuel pressure test. You can test the fuel pressure by getting a fuel pressure gauge and attaching it to the test port on the fuel rail and watching the gauge as somebody tries to crank it over if the gauge reads beetween 40 and 60 PSI then the pump is good if not then replace the pump most likely if pump is bad you will get a reading of 0 to 5 PSI. Hopefully this helps.
i am a land rover master tech,the first thing to do is make shure you have a good battery.test the fuel pressure and if there is no fuel pressure the fuel pump will take out the crank sensor leavig vehicle with no spark. so if you have good fuel pressure and no spark it sound like your crank sensor is bad.common problem. i hope i was able to help you.
Fuel pressure should be around 40. If the injectors are not getting power it will not start. Start with a crank sensor first.
First make sure your fuel pump fuses aren't blown. If they are ok you will need to check the wiring harness from the fuel pump and make sure it has fire to it. If it does it is probably the pump if the engine is firing and you are not getting fuel.
check the tubing :)
If you turn the key on you should hear a humming sound for a few seconds ,If no sound then fuel pump is not working,providing it is a newer model vehicle that has an electric fuel pump.Also you should connect a fuel pressure gauge to the fuel line and check the fuel pressure.
To test for fuel: Ensure fuses are good ensure there is fuel pressure via shreder valve with fuel pressure test gauge. ensure injectors are getting pulse, with noid light Has recent work been done?
What you may be looking at on the V8 is the fuel pressure test port. This is used to test the fuel pressure with a gauge. It should have a cap on it. Good Luck!
sounds like a fuel problem check first for a plugged fuel filter if filter is OK, it is likely a fuel pump, if you have access to a fuel pressure gauge check fuel pressure a test port is located on the back of the manifold on the drivers side should be around 60lbs of pressure if not you probably need a fuel pump. the other alternative if filter is good and fuel pressure is good it may be a plugged catalytic converter
If you look at the fuel rail. The rail that has the injectors connected to it. Some where on it (usually on the front side of the engine) there should be a port that should have a plastic cap covering it. Remove this cap and then you can attach a fuel pressure gauge or whatever to it. Good luck.
are you sure you reconnected the wire to the gauge when you did the fuel pump? also the gauge requires a good ground to the tank. its possible you don't have a good connection. just some thoughts.
check fuel sending unit and float. Also check fuel gauge itself.
Check your fuel filter for blockage/fuel flow 1st, then check fuel pump delivery pressure and volume with a pressure gauge( best get an EFI repairer to do this), bad / dirty air filter - check it, or bad / dirty fuel in tank, work from this and re post if no luck - good luck
Typically you'd attach a pressure gauge to the fuel rail or wherever the shop manual dictates then turn on the key. If the pressure is within spec you're good to go. If it's low pump replacement may be indicated. Cheers
I have worked on many engines, I would guess broken valve. Check every cylinder with a pressure gauge. If zero broken valve, if all have good pressure, timing. If timing good, fuel. maybe flooding.
loosen the fuel line and if fuel squirts forcefully out the pump should be good,but it's really hard to tell pressure wise if you have fuel injectors they need a specific pressure to run.
Either replace with a known good switch or with a manual oil pressure gauge
