Use an ohm meter to make sure you have power going to the fuel pump.

What would cause my1999 G20 to crank but no start?


First I would check your fuel relay. Next you need to check that you have fuel pressure at the rail on the engine. There is a valve that looks like an air fill point. You will need to get the proper tools to do this which you can borrow from an Auto Parts store like OReilly or Auto Zone. Wouldn't hurt to change your fuel filter while you are at it.

My 95 lincoln town car will be fine and then all of a sudden I can't get it to crank. I have changed the fuel pump, the fuel filter, I have sparks because I got shocked. was taught a trick of pushing...


check all your rounds on the body, behind kick panels, and in engine compartment. The relays you hear clicking are the power relay whcih turns your engine computer on. The other relay is the fuel pump relay, which is turned on by the engine computer. start there, report back.

PS. When you press the gas pedal to the floor during cranking, it shuts off the fuel supply to clear a flooded engine.

No fuel up to injecter pump truck just stalled


Did you check for fuel pressure on the line from the tank while you had the filter off? Do you hear your fuel pump prime when you turn the ignition on? First I would listen for the hum of the fuel pump when you turn the key to the run position (not starting the engine) May have to get a helper and listen at the gas filler neck with the cap off. If you dont hear your fuel pump, check your fuses and relays. If the relay clicks when your helper turns the key on ( put your finger on the relay and ear down close to feel/hear the relay actuate)., and fuse is good, yet you do not hear the pump prime, I would say your fuel pump is shot.

If it is a diesel,check for fuel pressure coming off the direct drive pump hose while cranking the motor.

My van wont start, it turns over but acts like it is not getting any fuel. Could it be fuel pump or filter?


did you check the spark if occur when cranking engine, if it have spark, direct fuel pump by shorting 30 and 87 pin off fuel pump relay and check if theres fuel go to fuel injectors, check for pressure, if no fuel, connect voltage directly to fuel pump assembly, if fuel turn s, check circuit, if no fuel goes, check the tank for empty fuel, if you have fuel change the fuel pump including fuel filter

My 1991 lexus will not start when the ignition is turn with the key. The ingine constantly turns over without starting and preceeds to kill my batterie.


Well if it is cranking you need to see if you are getting spark and fuel.....Try turning the ignition on without cranking the motor....You should hear your fuel pump making a whirring sound for about 3 sec.and then shut off...If no sound from pump (which is located in the fuel tank) check the fuel pump fuse If fuse is good check fuel pump relay...If all checks out ok with fuel pump take into consideration when the fuel filter was changed last....I dont recommend adding fuel injection cleaner to your tank without first changing fuel filter...additive is designed to break up debris thus breaking up all trapped particles in filter sending debris through your injectors.... To check for spark pull the #1 spark plug wire and place it on an angle on tip of plug (allowing you to see if spark is present) have an assistant crank engine while you look for spark..... Do not hold spark plug wire in your hand while engine is cranked.... I hope this has helped you

ENGIN CRNKS BUT DOESNT TURN OVER. SOUNDS LIKE ITS


The easiest way to tell if your fuel pump is running is have someone inside the vehicle turn the key to the ON position... put your ear against the gas filler.. if you don't hear it buzzing your fuel pump is either bad or not getting power. If your fuel pump is bad, you will have to drop the fuel tank. be careful not to just let it drop down after you loosen the straps, this could lead to dammaged fuel lines.
Good Luck!

Engine cranks but won't start, no fuel. Fuel pump and filter just changed. Accident button reset although the button feels free, no clicking or activating.


you going to have to narrow it down to see what part is defective. first check make sure you getting sparks by pulling one of the cable and use spare plug and ground it making sure you getting fire when turning engine over. 4 things need to check for fuel delivery. fuse, relay, fuel pump and crank sensor. assumed fuse and relay are good, using 12v light tester locate the fuel pump connectors and connect pos and neg terminal and have someone turn engine over and see is you getting any power to the pump, if the pump is good, crank sensor will be faulty, what crank sensor does it sense the flywheel turning sending info to the ECU then the ECU send power to the fuel pump. keep in mind, fuel pump will only turn on as long the crank sensor sense the flywheel turning.

Engine cranks, but won't start. Car has gas-Confirmed. Air Filter clean. Problem developed over several days. (i.e. harder & harder to start each day.) No problem noticed in engine/vehicle performance...


test replace the fuel pump relay, make sure the relay socket has 12 volts to 2 of it's terminal when the key is held in crank position, if not you may have a defective ignition switch or Powertrain control module (PCM)

1991 Honda Accord cranks but will not start


I think you should check the air filter or air intake. It seems like it's not gettin and air to start since when you spray the starting fluid it's runs but stop and it stalls. I think that it's the air supply for the car.
