I have no spark on 2 cylinders

[Jonny]

I have a '95 Talon, I have no spark on 2 cylinders. (cylinders 4 &1). Both run off of one coil pack. So I went to Auto Zone, got a new coil pack, put it on and still have no spark. Then put on a new control module, and still no spark. I went through all the wiring and made sure all the connections were good and cleaned them up, and looked timming over about three times, and still no spark. Did a full compression test, and there is 120 psi on all four cylinders. The only thing I can think of that could be wrong, is the Cam Angle Sensor, not sure if it sends a multiple singal from one coil pack to the other, but the car will run on two cylinders.

May be the ECU check to see if you have output from that to the coil

 

[Jonny]

Ill have to look im just not sure any more i did a full head job on it i put like 10 or 15 miles on it parked it and its never started after that

 

[Jonny]

And it has a new crank sensor

Did you check your Cam Angle Sensor?

Did you check your coil pack?

This may not have anything to do with your firing problem, but 120 psi is very low numbers for compression on a 2g.

I'm pretty sure the service limit is around 133 psi if I'm not mistaken.

Did you let the car warm up completely before you did your compression test??

 

[Jonny]

It has a new coil pack new crank sensor new control module. I cant warm the care up when it will only run on 2 cylinders. Im sure the compression is better than what i said it was becouse i did a full head job on it and before i did it i only had 115. Im going to try a new Cam Angle Sensor i should get it on wensday

 

[Jonny]

Well im going to get my new cam angle sensor today this better work i put so much money in this danm car theres only 247 miles on the danm motor i rebuilt it from the bottom up the only thing thats not new is the trany

 

[Jonny]

Wish me luck guys

 

[Jonny]

So i go to pick up my part and its the NOT THE RIGHT ONE its was for a 97 eclipse

 

[SBR Joe]

Do you have a 6 bolt swap??

SBR

 

[Jonny]

no 6 bolt swap

 

[AndrewD5418]

I think all 7 bolt CAS are the same...

 

[Eastwood95]

The 95-96's came with different ECU's and Cam Angle Sensor's

 

[numlock666]

the 95-96 have a cam angle sensor at the intake cam gear and a crank sensor down under behind the harmonic balancer. What I dont get why only two would only be fireing, i dont think the sensors send out two signals, or if it did it would be across the same wire due to only one signal wire from the crank and cam sensors. I think the problem lies somewhere in the wiring going to the coil.

Ok guys i got it the cam sensor was bad cars runing good thanks guys

 

[Eastwood95]

Where's my props?

Where's my props?

thanks man
