What else can I help you with?
What is wrong if your 1990 Chevy Lumina won't crank?
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.
What do i check on 1985 grand marquis if turns over but wont start have power to coil but no spark?
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.
Buick 3.3 v-6 will not start good fuel pressure and spark will start with starting fluid?
Fuel pressure should be around 40. If the injectors are not getting power it will not start. Start with a crank sensor first.
How do you test a fuel pump?
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.
I've got a 86 Lincoln Town Car that won't start after changing the fuel pump. It has good fuel pressure going to the injectors. Can you tell me what's wrong?
check the tubing :)
How do you know if the fuel pump is not good?
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.
2006 corolla engine cranks will not start fuel ok?
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?
Should the vacuum line above the fuel line be capped or should a hose be connected on a 1997 Ford Explorer V8?
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!
1996 Chevy S10 starts hard but does not stay running dies if gas peddle is pushed?
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
Where is the fuel pressure port on a 1997 dodge 1500 truck?
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.
Why would the fuel gauge stop working after replacing the fuel pump on a 1995 Chevy Silverado?
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.
Fuel gauge on 98 c1500 dont work fuse is good What is next step?
check fuel sending unit and float. Also check fuel gauge itself.
Why is engine losing power chugging then back to normal?
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
How do you check the fuel pump on a 2003 Toyota Solara?
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
What causes exhaust backfire on 1989 Mazda B2000?
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.
How do you test the fuel pressure regulator on a 1992 190E Mercedes?
To test the fuel pressure regulator on a 1992 Mercedes 190E, first, relieve the fuel system pressure by removing the fuel pump relay and running the engine until it stalls. Then, connect a fuel pressure gauge to the fuel rail's test port and turn the ignition to the "on" position without starting the engine to check the pressure. Compare the reading to the manufacturer's specifications; if it's outside the recommended range, the regulator may be faulty. Additionally, check for any fuel leaks around the regulator and ensure that the vacuum line attached to it is in good condition.
Chevy Cavalier Fuel Gauge not working?
If your Chevy Cavalier's fuel gauge is not working, it could be due to a faulty fuel level sensor, a broken wiring connection, or a malfunctioning gauge itself. Start by checking the fuse related to the fuel system, as a blown fuse could cause the gauge to stop functioning. If the fuse is intact, inspect the wiring and connections at the fuel tank and gauge. If these components appear to be in good condition, the gauge or the fuel level sender may need replacement.
