Just did motor swap on 95 f150 pulled 5.8 efi and put in another 5.8 efi haven't hooked up any vacuum lines get no fire?


No, but the computer does. The PCM was programmed for the original engine. If the parameters of the engine and the software in the computer don't match the engine won't start. The PCM may need to be reflashed..needs a professional or you can fry a PCM, and they are not cheap! Yes even 95 are flashed with firmware.

Car swings but no fire on plugs ?


Car swings ? It's cranks ! When you turn the key to the start position the engine cranks or does nothing ! No fire on plugs ? No spark ! You want answers to your questions ,get the proper terminology ! You have a crank - no - start condition ! Check crankshaft position sensor , ignition module , PCM - engine computer , coils etc....

Can the camshaft position sensor be a problem to start the car


Nope, it will make it crank more before starting, but the cam sensor just tells the computer what stroke the engine is on, the crank sensor is what the computer fires off of. You need to figure out what your car does not have. If it has no spark look to the coils and see if they are getting the signal to fire the plugs. If so, you probably need coils, if not look to the crank sensor. see if you have voltage where you need it. If you have fire check for fuel pressure, if you have fuel pressure and fire make sure the injectors are firing. If it seems you have everything make sure the engine is in time.

Outlander2004 start but wont fire up


You mean it cranks but won't start ?
If the check engine light is not on when you turn the key on, the engine computer does not have power from a fuse, or the computer has failed.

Car turns over well fires but wont run


you need to have the engine coolant switch checked,since the computer relies solely on sensors,the ect tells the computer how cold or hot it is so the computer will make it a rich or lean mixture to start the engine,if it tells the computer that it is 75 degrees the computer will lean the mixture like starting a car in the winter without a choke.

Only one injector is firing


There is a sensor on the camshaft that send the signal to the sparks plugs and to the injectors in order to have spark and fuel in the right time. Check first this one. Is still dont have the right fuel on time, check your computer. If not the computer, not the sensor, then check your engine timing.
