Question about 1999 GMC Suburban
I HAVE A 1999 SUBURBAN WHICH I JUST REPLACED THE TRANSMISSION IN. I WENT TO START IT AND IT WOULD NOT START BUT SEEMS TO LIGHTLY BACKFIRE THROUGH THE INTAKE. IT SEEMS LIKE IT IS OUT OF TIME. I HAD LOOSENED THE DIST CAP AND COCKED IT TOWARDS THE FRONT OF THE ENGINE TO PREVENT DAMAGE BEFORE I SET EVERYTHING LOOSE BUT ENDED UP DAMAGING THE CAP ANYWAYS. I REPLACED THE DIST CAP AND BUG CHANGING ONE WIRE AT A TIME. SOME MECHANIC FRIENDS OF MINE THOUGHT THAT I MIGHT HAVE PINCHED A WIRE BETWEEN THE BELL HOUSING AND MOTOR. COULD THIS BE MY PROBLEM OR DO YOU HAVE ANY OTHER SUGGESTIONS WHICH ARE HOPEFULLY EASIER TO SOLVE THAN THIS ONE.
If there is a pinched wire you will be able to feel/see it. If the dist cap got damaged, then it is possible the distributor got bumped or bent during the changeover. The first thing to do, is check, and recheck that you have all the plugwires at the right places. (18436572) Make sure that your wires are set in this order on the distributor cap. If they arent, then there is your problem. If they are set right, then check your timing. Or have one of your friends come redo the plug wires, and timing from scratch.
