  • Cam difference

    I got my engine in and tried to get it started. I cannot get it fired. I am getting some kind of spark because I am getting smoke out of the exhaust. While the engine is turning over it FEELS like it wants to fire but does nothing. I figured maybe the timing was off so I checked that. All was well. I am at my wits end. The only other thing I can think of is MAYBE I put the cams in the wrong spots (swapped int and exh). Is there a way I can look and see without pulling the carriers out? Any info on cams OR why I cannot get this pig started will be appreciated! THANX

    you can probably see by just pulling the valve covers off and seeing which cams are acting first. it'd be pretty obvious if it was backwards when you rotate the crank.

      I couldn't see any obvious markings on the cams so I had a buddy put his hand over the respective intake port and check for a suction. It was there. For the sake of my own dignity I won't say what was wrong but it was REALLY stupid. All is well now though. Thanx for reply.

        Well,perhaps someone else will benefit from your mistake. Trust me, no one here is perfect. We have all done some stupid shit and fixed a problem (forget to put memcal in computer comes to mind).

          OK... DOnt let the laughs kill you. I had checked and recheck mechanical timing over and over and all seemed well. I decided to see if for some dumb reason nr1 piston wasn't at TDC when the mark on the timing chain cover said it was. So I did the old screwdriver in the sparkplug hole trick and manually turned the engine over.... Holy crap!! The screwdriver is being pushed UP!! Then it dawned on me. Like a dumbass I was thinking nr1 was on the passenger side FRONT BANK when it is in fact on the REAR BANK! I had the sparkplug wires done with 1, 3, & 5 in front and 2, 4, & 6 in the rear.

          The morale of the story is..... Don't be a dumbass.

          This does bring up a good question so I wont start a new post for it. Which way is correct for spark plug wiring on the ign modules in a 95 Monte Carlo?

          1) 1/4, 6/3, 2/5 (With wire connections away reading left to right)

          2) 1/4, 3/6, 2/5

          Option 1 is in my Haynes books and in the 91 Lumina shop manual. It is also on my spare set of coils from a 91 Lumina.
          Option 2 is in the vehicle emissions label under the hood.

          I have driven the car with the coils both ways and I can't notice any difference in performance. Can any verify which is correct? Thanx

            Either way is fine as it fires both wires on the coil at the same time.
