You have either a bad primary pump or a fuel line that has a small hole in it. Look for any damp or wet spots on the fuel lines or around the pumps, up to the injectors metal or rubber/hose.. To include supply and return lines. If all are good, throw a scanner on it and read all the pressure sensors. Fuel and oil. Since you can prime and start. It is a fuel line problem. Could be a primer pump also if you have one. Some thing is causing it to bleed the fuel out. Pump problems cause it to just not start, or a lot of white smoke because it is sucking air. Which really goes back to a bad seal or broken line/hose.

SOURCE: fuel pump won't run unless engine is cranking, but won't start

Are you sure it's running when cranking? It should have come on when key turned on.
This is for camrys up to year '91. It may apply in your '95, also. Check the 7.5 amp ignition fuse and the 15 amp EFI fuse and the EFI main relay, all located in the fuse box next to your battery. There is also the circuit opening relay tied in to fuel pump operation. It is usually found under center of dash. It is usually not the problem, but it is part of the checks for fuel pump operation.
If your car has a " check connector" or "service connector" (also called a fuel pump check connector) under hood on driver's side near the firewall (a little 1 inch cube with a cap on it), then bridge terminals +B and Fp with a jumper wire. Turn key to on (don't start car). The pump should come on. Listen for fuel return noise from the fuel pressure regulator, and verify pressure in hose from the fuel filter. If nothing, check those fuses above. Here is how power runs to pump: Battery to 40 amp main fusible link-to 15 amp EFI fuse-to EFI main relay-to circuit opening relay-to fuel pump-to ground. Ignition switch and the computer (ECU) work the relays to pass power to pump. Hope this helps some, Randy. Good luck.

Check the fuel pressure at the filter. Odds are the lift pump, located below the filter, is toast. Continual cranking of the motor with a bad LP wil cause the injector pump to heat up and burn out. Replace the LP and fuel filter. Bleed the system by cracking the inlet to the injector pump and bumping the enigine over so the LP will run. Once you have fuel at the injector pump, crack injectors 1,3,and 4. Crank the motor for no more 6 or 7 seconds at a time until it turns over. Give the pump time to cool for a couple of mintues between cranks. This process is easier with two people, one to crank and the other to watch for fuel and tighten the injectors once it starts. If the injector pump is fried at this point from cranking with no fuel, the motor should idle, but will stumble all over itself when the throttle is applied.

2004 dodge 2500 ram diesel


I'm not familiar with that particular vehicle, but most diesel systems have a primer under the hood. You will need to pump that slowly until you feel some resistance. That will push fuel to the engine. The other pump may not be able to push fuel through until the system is primed.

If that doesn't get you running I would suspect a clogged fuel filter. Most Dodge vehicles have one on the frame. Just follow the fuel lines until you find it. There may also be one attached to the pump primer.

Changing that filter would my next action. Whether the pump is in the tank or added on outside the tank, you may still need to prime the system after the filter is replaced. Air in the line may cause it to stall, just reprime and start again.

Good luck.

I have a 2011 GMC Sierra 6.6 turbo diesel I ran out of diesel I put to gallons of diesel and now it won't start what can I do


The fuel system needs to to have the air bled out of it. I suggest having a technician do it for you to prevent serious injury and damage to the vehicle.

6.6 diesel shut down after starting, still cranking strong but won't start.


I would double check to make sure no air was in line. If it still won't crank, has to be pump.

I changed the fuel filter in my 2004 silverado and now my truck won't start


It would be nice if you were to mention WHICH ENGINE your Silverado is equipped with...Knowing WHICH Silverado MODEL you have would also be nice...1500, 2500, 2500HD, 3500. etc.
If it is a gas engine, all you should have to do is to cycle the ignition key ON for about 5 seconds, then turn the ignition switch OFF and wait about 30 seconds, then repeat this about 3 times. This will allow the fuel pump prime to get the air out of the fuel lines. It should start after this is done.

If your truck is equipped with a diesel engine, the process is much different, let me know if this is the case, and I will post the fuel filter replacement instructions for the diesel.

My 2500 chey silverodo starts hardfor the first 10


Hi, if it's a diesel engine, they all have to sit for some seconds because of the glow plugs. Some diesel don't send power to the starter until the glow plugs run for the pre-determined amount of time. There are many things that could be causing this. Fuel filter, clogged injectors, fuel pump going bad or bad connection to fuel pump. Try checking out for this things..
Take care

Ran out of diesel, added diesel but now it wont start 2007 Chev 2500


Hello and welcome. you will have to perform the bleed procedure using the fuel prime on the fuel filter housing. there is a pump on top of the fuel filter assembly, on the passenger side of engine.

Open the vent valve screw (1) by turning the screw counterclockwise several full turns.




Operate the priming pump (1) by repeatedly pumping until a small amount of fuel seeps from the vent valve. Allow the pump to fully return upward between pumps. When fuel is present, the filter is full of fuel and the system is primed.
Close the vent valve screw.

Chevrolet 2500 Not Running, May Be Fuel Filter Sensor


That red wire is only for the fuel heater.will not cause a no start.try pumping the primer pump on top of the fuel flter hsg. but first open the bleed screw,which is black plastic also located on the top.this will eliminate any trapped air that might have entered the fuel intake system.if the pump does not get firmer and harder to push, then you have a leak in the fuel supply lines or the ck valves in the fuel filter hsg or stuck open. Still no start have it scanned to ck fuel pressure while cranking.it should be close to 5000 lbs
