SOURCE: New fuel pump but no gas to the fuel rail

When I first posted, I did not read "comments" after reading what you have done and our results, it seems as though the engine control system "thinks" the engine is running when it is not. I don't believe this is a key switch problem, otherwise if you turned the key to "on" it would flood the engine. Therefore there is a strong possibility that the engine control unit is staying "hot" even when shut down, permitting the pump relay &injectors to receive trigger signals .BUT, I would also take a look at the pressure regulator on the fuel rail. flow through there may be causing the pump to stay on if too much fuel is being bypassed. And, again...did you check codes???

I have a 1994 Plymouth grand voyager it has the 3.3 it cranks but will not start it's not getting no fire to coil.crankshaft, camshaft,ASD,fuelpump

No fire to the coil? Does that vehicle even HAVE a coil, or is it a coil PACK? Just to make sure the Automatic Shutdown Relay is not at fault, disconnect the battery for 10-15 minutes, then reconnect it and try it again ... but LISTEN carefully for a "groan" of about 1-2 seconds when you turn the key ON but not far enough to crank the engine. That will tell you if the fuel pump works. If there is no sound, with the battery connected and with the key in the ON position, take a rubber mallet and strike the bottom of the fuel tank a few times, until you hear the fuel pump turn on, even if it's only a second or two. Then try to start the engine again. Good luck!

I have a 1996 Subaru Impreza started it went to back up it's stalled now it will not start again it turns over there is fuel in the fuel line when you turn the key if you remove the hose it is getting fuel...

Try spraying a little ether into the air intake. If it fires and tries to start it indicates a fuel system problem rather than a spark problem.

From your description the problem could be too much fuel. I have experienced similar things several times before. Killing the fuel pump and cranking with the throttle wide open in several 10 second bursts with 10 second rests between will help disperse excess fuel. It could even fire or run for a couple of seconds and if it does it will be time to replace the fuel pump fuse and try again but keep the throttle open a little.

If that doesn't work please come back again for further advice.

Turns over and won't start, replaced fuel filter and just turns over and almost fires

Almost fires? Do you mean it does fire some, that you know the plugs are getting spark? If so, then you probably need to have your fuel pressure tested to see if pump is working properly. Can you hear the pump buzz on briefly when you turn key to on? It should come on for a couple of seconds to pressurize the lines. If you don't hear it, then your pump may be bad, or something not turning pump on. Good luck.

Starts then dies & won't restart

check fuel pressure, should be 40 psi.
try 2 things

spray starting fluid in air intake to see if it will stay running. It's fue then.

Try turning key to on nd wait 5 seconds for system to build pressure and pump to shut off. Turn key off, wait for relay clcik noise or 10 seconds. then turn key to ON again and wait 5 seconds to build pressure again. Then start engine. If it starts better, you have a bad check valve in the fuel pump or a bad pressure regulator on the fuel rail (unlikely).

I have a chevy colbalt 2006 ls .it is fuel injected. i ran out of gas and now it will not start even after making sure fuel tank is full ......

It probably needs a little priming. In order to do such priming, I would turn the key on for about 20 seconds, until the fuel pump goes off. Then, turn it off, do it again. Do it twice more, and it should be primed. Just to make sure, spray some ether down the air intake, and try and fire it off.

Hard to start after it sits u have to keep cranking for at least 30 t0 45 sec

When you turn on the key the fuel pump relay causes the pump to run for one second to bring the fuel manifold presure up. If the vehicle has 'sat' for a long time, this one second is not long enough and so the engine is struggling to get enough fuel to fire. Try turning the key on and off every couple of seconds for about a minute, then turn the key to the start position. The engine should now start. Do not touch any controls such as the throttle, the computer will take care of all this.

Takes multiple times to start

I think you have a faling fuel pump or a bad pressure regulator allowing fuel pressure to bleed down when the engine is off.
Try this test - When you start the car for the first time of the day, turn the key to "ON", wait a few seconds, turn the key off. Wait about 15 seconds, turn the key to "ON" again, wait a few seconds. Then wait one final time for 1 seconds and try starting the car. If it starts right away, that means fule pressure is bleeding of due to a bad check vavle int he fuel pump, a bad fuel pump or a bad pressure regulator.

The reason for the procedure is because when you turn the key to "ON", the fuel pump runs for 2 seconds and then shuts off if the engine is not running. The 15 seconds wait is for the power and fuel pump relay to cycle off before it will run the pump again.

Let us know how the test comes out. The fuel pump is in the fuel tank and hums when it is running.

Problems when starts..

Turn your key on for 10 seconds but do not start the engine. That will give the fuel pump time to built pressure. After the 10 seconds try starting the engine. If it starts right away you may have a weak pump or dirty filter.
