check your pump if you replaced the pre pump in your fuel tank you must check the seal .remove the plastic ring check the base at the entry to your pump is flat .it may be leaking air due to your seal not seated in correctly.

If a starter is able to crank the engine but it won't start you usually have either an electrical or fuel problem. It's also remotely possibly that it's compression.If an engine has proper fuel, spark and compression, it will start when you crank it. So your challange is to find out which part isn't working right. Start with fuel. Spray a little starting fluid into the air intake while someone tries to start the engine. If it starts briefly when you're spraying starting fluid, you probably have a fuel delivery problem. That could be injectors, fuel pump, fuel filter, relay, fuse... who knows what until you check into it.If it doesn't start with starting fluid, check the spark. Pull a plug wire and attach it to a spare sparkplug and set the plug on a solid metal part of the engine. Have a helper crank the engine while you watch the plug. If you have a good spark, it might just be out of timing.In any case, you'll need to start isolating the problem. Find out which part isn't working then you'll know what to replace/repair.

check your codes first as it can be a number of things.

hi there
without physically looking at this it is hard to say but best thing i can suggest is that the fuel relay is bad this is a fuse located usually under the hood and will be marked on diagram
hope this helps have a great day

My first thought is to check the fuel pump operation.
Check to see if fuel pump is getting power.

This is how I check the pump.

Usually there is an in-line fuel filter that can be removed.
While its removed...bump the starter to see if gas shoots out the gas line.
If not, there might be a clog at the pump...or the pump needs replacing.

Hope this helps...

Inspect your fuel line and see if it's supplying the fuel, if not then you need to check if fuel pump is working or not. if not change the fuel pump and fuel filter. Good Luck

Have you replaced your fuel pump relay?

you are having a fuel delivery problem...and it could be caused by numerous things...such as a bad fuel pump, a bad cold sensor or warm up injector.  You haven't attempted to  solve any of these suspected faults...so take it to a mechanic for repair

Give it an good tune up wires,plugs,gap,rotor.
