No fuel being delivered to engine

I have checked the fuel pump and filter both are new and in good shape with fuel being delivered to the rail but engine will not run. Before I pull and order an EFI control box wanted to know if there is anything else i should check first.

Fuel rail pressure too low


You didn't say whether petrol or diesel engine...

In the case of trouble or doubt regarding fuel filters it is best practice to cut open the filter and carry out a close examination for possible contaminants.

Fuel pressure is important, in fact a common rail diesel won't even start if there is insufficient pressure, but the volume of fuel delivered is at least as important as the achievable pressure - without sufficient volume the required pressure simply won't be achieved.

No fuel system check is complete unless the delivery volume has been tested and found satisfactory. If it isn't satisfactory the fuel tank, the pump screen, the pump and pipework should be checked. The pump screen if fitted is so fine water will not pass through it and so water in the fuel tends to reduce the volume.

I suggest you have the fuel system checked - properly!

Fuel pump works, new filter, gas is coming out past filter but not getting to the Compression tester. I changed the vacum valve on the gas rail. What next?


The presence of fuel isn't enough.

Fuel must be delivered in sufficient quantity at a sufficient pressure and this can only be checked with a fuel pressure test and a volume delivery test.

Why still no fuel pressure


Are you checking fuel pressure at the engine fuel rail with a pressure gauge hooked up, and key on? And you still hear the pump turn on for 2 seconds with key in on position?
There should be pressure in the fuel rail then. If not, is it possible you put the new filter in backwards? I would take off the line going into the filter from the gas tank, and leave off for a test: you're right, the pump turns on for 2 seconds with key on to put pressure in the line and the fuel rail. But then when the engine is cranking, the pump is turned back on. To check if the pump is picking up fuel, have someone crank the engine over while you watch at the filter: gas should shoot out in a good stream. If it doesn't, check for a kinked line from filter to the tank. If the line is good, you will have to take the tank back off and see why the pump is not picking up fuel and sending it out.
Let me know what you find. If the pump shoots out gas at the filter area, but still no fuel pressure at the engine, check the line from the filter to the engine-may be kinked, blocked, or clogged.

Engine flooding


Check the fuel pressure. The pressure regulator may have gone bad and is delivering too much pressure to the fuel rail, thereby flooding the engine.

Where do i find fuel pressure regulator on an 2001 tracker v6 the engine is starving for fuel when going down the hwy allready replaced fuel filter


it's on the end of the fuel rail. Vacuum operated regulator failure usually results in rich condition. You should check pressure to see if your pump is getting the job done. Cannot find the spec on pressure but a new pump for your car delivers 80-100 psi. Let me know if you have more questions.

Where is fuel filter located in a kia sportage 2006


The fuel filter is bolted to the frame rail below right of the battery. It is cylinder shaped and has a fuel line at each end.
Procedure for removing it:
Find the fuel tank access plate under the rear seat. With the engine idling disconnect the fuel pump wiring harness and let the engine stall. This relieves the fuel pressure.
The lines on the fuel filter itself are "quick connect" fittings. Depress the tabs on the fuel line and push TOWARDS the filter. The line should pop off. It's difficult to depress the tabs and you CAN use a pair of pliers but be careful or you'll damage the fitting.
Reverse to install new filter. Reconnect fuel pump, start the engine, and check for leaks.

2004 KIA TROUBLE WITH START UP AFTER FILLING UP WITH GAS


The fuel filter may be at the end of it life time and need to be replace. I believe the fuel filter is under the battery bolted to the frame rail. Its a cylinder shape with a fuel line on both end with quick connect fittings. IN the fuse box, remove the fuse to the fuel pump or the fuel pump relay with the engine running, this will depressurize the fuel line. The fuel line on the filter are quick connect fittings, depress the tab's on the fuel line and push towards the filter and the line should just pop off. If you find it to hard to depress the tabs, use a pair of pliers. But be careful not to damage the fuel line. Install the new filter, place fuse or relay back in for the fuel pump. start the engine and look for leaks. If the check engine light came on, disconnect the battery to clear the light, but make sure the radio is turned off before you disconnect the battery for 5 min. Reconnect and everything should be good to go. Hope this helps. keep me posted.
