Car is not fireing on 1 and 4 cly ideas please.

My friends 96 spyder gs was just changed to a gst with a 6-bolt motor its been fine intill now. He was coming to my house when he felt the car loose power and it idles at 450 500 rpms it sounds just like it should at 750 800 rpms . I looked over the car and found it is not fireing on the coil pack on the left side of the motor (faceing it.) I looked at some other cases of this in the fourms and it makes me belive the cam angle sensor is bad it was used and old. But then again is there something else that I can look for to find why this is happening. We changed the coil and the big plug that goes on the plate that is next to the coils (forgot the name of the plug) and now im out of ideas is there anything else I can look for.


Thanks

AJ

I just had this problem and it is probably the cam sensor. I got one from Mitsu for like $60 but it sucks to put them on for all the crap you gotta take off to get to it. Here is a quick check to make at the power transistor: ( big plug that goes on the plate, as you referred to it). Using a test light connected to battery positive, probe the 2nd wire from one end (2,3 coil) and the second wire in from the other side (coil 1, 4) . The light should come on with key off. As you are cranking the light should flash on both wires.

You will probably get only one wire to flash ( your good coil side ). If so I would look to the cam sensor next. You can find specs. in your manual as far as voltage and resistance. There are 3 wires on it. Should be red, black, blue I think. The blue is signal voltage. Check that with a voltmeter and see if it is within tolerance.

Anyway, the only other thing would be the ECU. If you have access to a scanner see if you get the Cam sensor code. PO340. I am willing to bet this is your prob. Get back with some test results! Good luck

Found the problem Since this was a totally diffrent engine going into this car we had the use the old wireing harness and splice and solder a bunch of wires and one came apart that went to the power transistor soldered it back and all is good.

Jay rod thanks for the post you were only one.

Glad to hear you found your problem and got it all worked out. But that was no thanks to me. I didn't help much. But at least you got it going.
