If you car is a mid-1980's or newer it's fuel injected and pumping the pedal has no affect on it starting. A few causes are = clogged fuel filter, intermitent fuel pump activity [ pump, or relay ], faulty fuel pressure regulator, leak in system, etc. If you can hear the fuel pump run when you first turn on the igntion, then look for the filter or regulator problem. If there's a leak in the system then it may get air bound.

Possible fuel pump. Check the fuel pump pressure;or remove the air intake hose from the throttle body.spray some gas with a squirt bottle in thratle body. replace the intake hose and crank it; if it turns on, your pump is bad.

WILL START DRIVE A FEW BLOCKS , THEN SIT 5 MIN GO TO START AND WILL ONLY CRANK CHECK FUEL FUSE SOMETIMES BLOWN OTHER TIMES NOT HIT TANK THEN MAY START , MIGHT TURN OFF AND THEN MAY BLOW FUSE, REPLACE FUSE...


for 1 fuse blown evry so often then you must have a short somewhere, the fact that it will crank and not start is most likely ur fuel pump , had the same issue with getting fuel to start or keep car running, possible that short could be by the fuel pump, the fuel pump is located under the rear seat and if im not mistaken it is on the drivers side rear

2001 ranger wont start after sitting


check the fuel pump and see is working properly, if the pump is good than the problems will be the crank sensor is faulty. what crank sensor does it sense the turning of the flywheel and it send a single to ecu, and ecu send a flow of power to turn on the fuel pump as long it sense the flywheel turning.

Honda Accord 1994 V4 LX: Starting problems in the morning


There could be a few things causing this. When the car finally starts, is there any smoke coming out the exhaust pipe? White smoke would mean your headgasket is leaking and is letting coolant into the engine, then it is burned along with the fuel. Does the car run hot? Meaning has it ever overheated? Back to the smoke, if its black, your oil is getting in and is burning.

Now, the reason why it would be hard for a car to start, could be, a leaking headgasket, flooding the car while the car is sitting.

And yes, the car would be able to crank, but just wont start, for a while...because it has to get rid of all that fluid that has leaked into the engine while sitting at night.

Another thing you could look at, is your fuel pump, is it supplying a sufficient amount of pressure? If it isnt, it will take a while for it to pressurize and deliver fuel into the engine. You can check the fuel pump yourself by renting a fuel pump pressure tool from stores like autozone, kragen and more.

Your gas cap on tightly?

Good luck with your problem.

2005 sonata has been sitting for 3 months ,replaced battery yesterday but car just keeps cranking over'Idon't think it is getting fuel.


hi if the car was running ok when it was parked up and the battery is cranking at a resonable tourqe you will get it started with a bump start it may need to tow started as the valves and valve seats in your car get a build up of carbon fossilisation which results in low compressions i am presuming you not had a bump in it and thats why its been laid up becase if this is the case it will have triggered the fuel cut out switch just reset the switch yates210456

Car started to sputter on the road press peddle lightly to go slowly tried to go faster and started to do it again I put car in park and pressed peddle again and was sputtering


sounds like it needs a fuel filter. especially with the poor gas there selling us at the pump these days, despite the cost.
