your anti theft device is activated,you need to lock and unlock your doors a couple times with the key fob,not the key,and then you need to put the key in the ignition and start it,if you dont have your key fob,call your car dealer to get a new one,they are programmed for each car only,you cannot bypass it.
Look at the top of the engine and locate the fuel rail on the injectors. There should be a Schrader valve on the rail. Take a small screwdriver or a nail and push in on the Schrader valve. Have the helper turn the key on and look for fuel pressure at the valve. If there was no Schrader on the rail, just loosen the fuel line for the same results. If there is no fuel expelled, check the fuel pump fuse and relay located in the relay box. If these are not faulty, the fuel pump has failed and is need of replacement.
ok first question where did you buy the fuel pump tell me other try this when car is not starting go to fuel pump get a circuit tester have somebody else turn key to on position for ten seconds turn off then again if no noise from pump check for power at fuel pump there should be one wire that has power for obout ten seconds then cuts of. if power to pump and it does the ten second on and shuts of by it self then you got a faulty pump, now if no power at all on ten second teste then get a long wire thay can reach from battery to fuel pump hook up to your battery go to wire at fuel pump and hit it with wire from battery if you can hear pump going on them you have a bad contact ether at fuel pump conector or at relay conector or bad wire one thing when looking at conector at fuel pump you will find sevral wires two wires are for fuel level one power on ground other wires are for pump one ground and other for power to pump if any question ask me i will help i am a mechanic let me know
have diagnostic codes checked to see if you have a cam or crank sensor fault. make sure fuel pressure is at the required pressure, just testing to see if you have fuel at the valve is not enough. replace all spark plug wires. if you replaced two then all are just as old and even when they "look good" does not qualify as "they are good". Replace coil pack. start up drive away happy
I had a similar problem with an older corvette. It was the chip & reader on the key & ignition. It would fail me at the worst times! A new key & sensor did help but it was kinda pricey for what i got. Also check to see if your fuel pump is working properly. Locate the schraeder valve on the fuel rail (looks like a tire valve), turn your ignition on but dont crank. Push the centre of the valve in & see if any fuel squirts out. if yes, ur good, if very little then ur pump is being a Btch. The security feature usually triggers the ignition, not the fuel pump... This is a simple "no tools" procedure. Using the proper analytical gadgets will give u much more info...
WHEN YOU PARK IT FOR THE LAST TIME OF THE DAY TRY PINCHING OFF THE RETURN LINE ( AT A RUBBER SECTION OF LINE ) AND LET IT SIT OVER NIGHT. IN THE MORNING UNPINCH THE LINE AND TRY TO START IT. SEE IF THAT DOES IT. THE ONLY THING LEFT IT SOUNDS LIKE YOU MAY HAVE A CHECK VALVE THAT ISNT HOLDING. IF THAT DOESNT DO IT THEN IT IS A DIFFERENT SYSTEM THAT IS CAUSING YOUR HARD START ISSUE.
run scanner for trouble codes, some auto parts stores will do this for free,check fuses, check for fuel at fuel rail, if not check fuel pump relay, you should here it click when key is first turned on, if not try to bend tabs slightly to make good contact, if no click, replace relay if so turn key off then on listen in tank with cap off for whirling sound if tank, if not could be fuel pump, sorry
I think you should check your battery and alternator.If they both check good you may have a battery draw,something draining the battery over night.Check your doors make sure they are closing like they should.
