My 2000 Hyundai Elantra starts, idles for a few seconds but then dies right away. Before this it was idling rough with very little power when I stepped on the gas. I sprayed some carburetor cleaner into the air intake while the car was running rough thinking this might clean air intake a little - the car stopped running immediately. Could I have shorted out the Mass Air Flow Sensor or made it fail?
To help solve the problem, I’m looking for the Fuel Pump Relay to check it, but I cannot find it. It is not listed on the relay box under the hood, it is not in the fuse box in the passenger compartment. I found the Multiport Fuel Injection Relay behind the dash but where is the Fuel Pump Relay? I have replaced the fuel filter, fuel pressure regulator and throttle position sensor. When I turn the key to “on” the fuel pump does not “whirr” but I do hear it running after the car starts.Then everything stops.

You may need to check the belts on your car's power steering section. Make sure the belts are tight and not worn out. Check for cracks on the belt and if loose, tighten it. There is also a product called Automotive belt dressing that you can spray on the belt to make it stick more easily to the pulley it is supposed to turn.
Assuming you saying it cranks and cranks and then starts, but runs alittle rough or even dies when stoped or idleing, then it might be your 0xigen sensor, needs replacing. Hope this steers you in right direction. Let me know mike
IT could be the forward band or reverse band or pump in the g/box are holding on instead of breaking drive at 600 rpm,as its like putting in the clutch on a manual box it frees off the drive.
But you could check the Actuator but i would say check the bands by when stopping slip into N if idles ok then its the box Sorry
Let me know how you get on Ron
Sounds like it might be either the fuel filter or the fuel pump, cause if you ran the tank down, you probably had sludge in the bottom of the tank that you sucked into the engine, you can try using a fuel system cleaner, you may have sucked sludge into the injectors running it, Zmax sells a fuel system cleaner, or there is one called RUN RIGHT, I would try putting some of that in letting it sit a few min then after it sat a few to soak in and break down the sludge, then start the car up, kick your idle up to around 1500 RPM do not go higher then that cause you will damage the engine, try that and see if that works for you, if not then I is probably the fuel pump or filter.
hope this helps.
did you spray the maf sensor or intake hole ?if you didnt spray maf then probly not! have some one turn the key why you listen in the fill gas hole for pump noise ? sould here somthing for 2 seconds at least besure you ear is there before key is turned , also check you ecu fuse to see if it may be blown .? also you could try unhooking battery cable for 20 minutes neg side only then rehook it and try to start it! good luck
This almost sounds like the fuel pump check valve is leaking back during the day. Try this to see if it helps. Before you start your car during the day, cycle the key on and off a few times first. This runs the pump for a few seconds and builds up fuel pressure. If it starts immediately after the key cycling, that is most likely your problem.
