no spark

[derrecks92talontsi]

I have tryed everything coil pack cam sensor ecu. Why is there no spark it was running and I went to move it no spark. I have tryed 5 different ecus all off a running car.

[CornFed2.4]

Obviously its not the ecu. Did you try the transistor pack?

[EclipseGST]

All fuses and relay's good?

Cam sensor
Transistor Pack
Coil pack
Chassis ground and sensor grounds

Check wiring between the cam sensor and ECU and between the transistor pack and ECU as well as coil pack.

Is the fuel pump turning on when you spin the cam sensor?

[derrecks92talontsi]

The first thing that i checked was a transistor pack and cam sensor and the wireing both places. I can hear the fuel pump kick on when you try to start it plus it has good fuel psi. What am I missing to check.

[EclipseGST]

You obviously missed something... You check the wiring between the cam sensor and ECU? Check the wiring between the transistor and ECU?

Does the coil pack have power?

The fuel pump will turn on when you turn the key on to prime. But does it continue to run while cranking the engine? Pull the cam sensor out and spin it by hand and listen for injectors to click, fuel pump to run, or coil pack to fire.

[derrecks92talontsi]

I will have to try that man thanks I didnt know if you spin the cam sensor it makes the fuel pump and inj would click

[Goat Blower]

Yeah, the cam sensor sends a signal to the MPI relay kicking on the fuel pump, that's not it.

Did you swap out the transistor pack, or just look at it?

[derrecks92talontsi]

I swap it out with a 92 talon that was at the cookout same with the coil so I am sure that isnt my problem at all same with the cam sensor that i swaped out from the same car

[derrecks92talontsi]

I just check the cam sensor spined it by hand and I have spark but when I try to start the car no spark is it the ecu or what all the wires look good. What is the problem?

[dsmghost]

Make sure the cam sensor isn't 180 degrees off

[derrecks92talontsi]

It isn't but it should run it would just run like ass will not fire at all

[EclipseGST]

What plugs do you have?

Are you getting fuel at the rail?

Can you hear the injectors clicking when you spin the cam sensor by hand?

Can you hear the fuel pump run when you spin the cam sensor by hand?

[derrecks92talontsi]

The fuel pump running good fuel psi and the inj clicks and sparks when u turn the cam sensor by hand

[EclipseGST]

Well then, all you're missing is timing and compression.

Did you do a compression test?

When you put the cam sensor in, try rotating it clockwise a little bit to advance the timing. This is while the cam sensor is mounted on the head but loose.

[derrecks92talontsi]

New motor man no spark when I put the cam sensor on the head yes the compresion is good.

[EclipseGST]

Ok... Then its between the cam and the cam sensor.

If you spin the cam sensor by hand and everything works, then you put the cam sensor in the motor and nothing works... What does that tell ya?

I dont care if the engine is brand new or has a million miles on it.

Either the cam is not spinning the cam sensor, or your timing is way off.

Who put the cams in? Can you take a picture of the end of the cam where the cam sensor slides into?

If this is a new engine, it almost sounds like someone flip flopped the cams and the exhaust cam is where the intake cam should be to where its not turning the cam sensor.

[derrecks92talontsi]

No I have drove it for 500 miles then went to start it then nothing

[EclipseGST]

Ok... Still, check the cam where the sensor bolts.

Like I said before, if everything works with the cam sensor out, but nothing when its installed...

Either the cam sensor is bad
Wiring is loose somewhere
Cam is not spinning cam sensor
The cam sensor is not all the way in the head


Those are the only possibilities for the cam sensor to work when its out of the motor and you are spinning it physically with your hand vs being in the engine and not working at all.

Thats all there is, nothing else. So if you still cant figure it out, maybe get Travis over there or something cause thats all it can be.

[derrecks92talontsi]

That is were the car is at his house

[derrecks92talontsi]

But could it still be ecu or not the case i am sure the cams turn and the timming belt isn't broken. What else could it be.
