Try your fuel pressure regulator.some time it can get damaged when there is no fuel in the system. may have stuck shut.

SOURCE: My Car has been sitting

There could be 2 reasons for this. One is that the fuel pump burned out (you would be able to recognize this if you turn the ignition key over and get close to the gas tank you will hear it spinning). The other is there is a sensor on the bottom of the gas tank that reads when you are completely out of gas and you will need to contact the dealer on how to get it reset. Hope this helps you out! Have a good one!

SOURCE: i have a 94es300 i crank it it starts up runs 5 mins shuts off like not getting enough gas changed fuel pump, fuel filter , fuel pressure regulator and ignitor still same whats up with this car

If you changed the fuel pump and the fuel filter and ignitor and regulator,in the list of changes do you know you have a EFI. The EFI main relay turn on the fuel pump which includes the circuit opening relay. Testing it mainly passes with flying colors just replace

Pull the plugs,see if they are black. To much gas. replace the fuel pressure regulator. If white, not enough fuel. Check the fuel filter, if dirty or rust colored replace the tank, pump and filter again.

Have a 2002 Honda Civic that will turn over but will not crank,


check your owners manual for a fuel pump shut off switch if it has one, reset it, check for a blown fuse for the fuel pump, if that dosent work, check to make sure no wires got pinched in the bell housing between motor and transmisson.

2006 cobalt.replaed starter relay fuse all lights come on dash ect. fuel going to fuel pump but wont crank over


Are you positive the battery is good? Did you try to jump it ? Make sure all cables are clean and tight. When you say "won't crank over" do you mean the engine doesn't turn at all? If not, I don't know why you think the fuel pump would be the culprit. If it cranks and doesn't start, I don't know why you replaced the starter.

Disconnecting the battery doesn't reset the light. You need a scan tool for that unless you get lucky and fix the problem and go through enough cycles for it to go out on it's own.

Take it to Autozone or Advance or somewhere and have them read the codes. They do it for free for you. (They are hoping you will buy parts there) They can reset the light as well.

Air in the fuel line. Take one small wire off the starter relay and turn and hold the key in the start position for a while. Listen for the fuel pump. It will run fast for a second then slow down. When it does, put the wire back on the starter relay and crank the engine.

My 2002 chevy 1500 van , 4.3 liter v6, will not fire. ran great, no signs of trouble leding up to now. Cranks,cranks, & cranks but no sputter, fire, anything


I would check and be sure I had fire to the plugs and fuel to the throttle body. I read what you wrote about the fuel pump but then on the end of the description where you put gas in the van the pump might not be working. If so you could have a bad wire to the fuel pump or a plugged fuel filter. Once you verify those items I would pull the 02 sensor ahead of the catalytic converter in the exhaust and make sure the cat or muffler is not plugged. If they are it will put back pressure on the engine and not allow fuel into the cyl. to fire.
