96 Camry cranks but won't run. Fuel pump failed. Replaced it but the car won't start. It turns over but won't start.

What had you been doing to the engine before all this happened? Did it involve removing or changing the distributor? When the #1 piston is at top dead center, it can be on its compression stroke or at the end of its exhaust stroke. Back the engine off from the #1 TDC position, remove the #1 plug, and rotate back toward TDC with your finger over the plug hole. If you feel compression, then the distributor should be coming towards #1. If you don't feel compression, rotate the crankshaft another 360 degrees, then set your distributor to #1.

Will not start after sitting

Make sure your accelerator pump is working. When you press the pettel it should squrt gas down the barrel

How do I diagnose and replace the fuel pump?

What kind of car is it?

First you need to find out if the car is lacking fuel or spark?

Pull a sparkplug wire and see if it sparks while cranking the engine. Hold the wire near the engine and see if it sparks to the engine. if its a deep connector put a screw driver in it and hold that near (1/2") the block or any grounded metal part. If there is no spark then that\'s your problem and you must find out why. To check for lack of fuel open the air intake hose, between the air cleaner and the engine intake carefully squirt a little fuel in and crank the engine.. If the engine tries to run, fires, then you are missing fuel. in almost all late model cars that are fuel injected the pump is in the tank.. on most American and Japanese cars you must remove the tank to replace the pump. on many German cars you can get to the pump or pumps under the back seat. There is a relay that drives the pump. when you turn on the key you shoud hear a click followed by another click 1.5-3 seconds apart. Many time you can hear the pump run for this short time. Open the cas cap and listen for the pump running. These pumps are expensive and many times hard to replace. Make sure the pump is bad before you go to replace. And last.. Possibly first.. Remove the fuel filter blow through it and make sure its clear. Since you have it off replace it. Good Luck.

Car turns fuel to the engine....

Check when starting if the fuel pump runs. If it does not, check the wiring. If you are sure with the relay and its terminals, it may be the car's computer module that may be bad. If the fuel pump runs during start, check if fuel runs to the engine after the fuel filter. If it is a new fuel filter, check if the fitting or connections are correct. If there is fuel after the fuel filter, it may be the injectors since fuel goes to the engine. Also related to the fuel being injected to the combustion chamber is the MAP sensor which measures the air in the intake and tells the engine how much fuel is needed. Check for the intake from the air filter for holes or tears. Check for loose vacuum hoses.

Will not start unless you pour gas in top of engine

looks like the computer for the car is gone. fuel regulating is done by the computer with the help of air intake and the exhust O2 sense.
you can have the garage chek the air intake meter and the O2 sense, before you change the computer unit.

you have a voltage drop problem probably a coroded wire if you can open wire harness and do voltage checks down the wire until you find the bad spot and repair or you can run a bypass wire

it's look like the problem came from the injectors. they we're clogged. because hen the ngine still cool, it need much fuel than at working temperatures.
