Cracked head, blown head gasket would be my 1st thoughts. Check the radiator for bubbles while the engine is running, this is a good indication that the head gasket has blown or your head is cracked. It should be overheating if it has either.
well if spark quits fuel usaly will to computer will do this to stop cadilac converter from filling with fuel!and causeing a fire saftey feature!!!!okay disconect battery wait a couple of minutes reconect! turn key on postion do not start or crank!off then on until you hear a GRRRRunt that is your fuel pump that is what you should hear turn your head to the right towards back seet and once you hear it that means pump is good then crank it then spark should quit if the coil packs a r bad then you have your problem if so test for spark also if you have eng light on cut the case hook up obd 2 scan find the fault and fix THIS IS WHAT I WOULD DO CHEERS!
do you have power to the other coil?? tried another coil?? is wiring loom ok and the insulation on the wires not broken and cracked inside the loom.if all these ok then it might mean a new ECU unit
Typically timing belts need to be replaced every 60,000 miles, in order to prevent them from breaking or loosing teeth and leaving you stranded, or possibly damaging the engine. I doubt the timing belt is causing your engine vibration issue. I would suspect that a good tune up would take care of that problem.
1. Disconnect high-tension code from spark plug.
2. Remove the spark plug.
3. Connect the spark plug to a high tension code.
4. Hold the spark plug with insulated pliers 5~10mm from a ground.
5. Crank the engine and verify that there is a strong blue spark.
If there is no spark, inspect the following points.
Step Inspection Action
1 Check for good connection of ignition coil Yes Go to next stop.
No Repair or replace
2 Check if resistance of high-tension leads are OK Yes Go to next step.
No Replace
3 Check if the ignition coil is electrically charged
1) Ignition switch "ON"
2) Check if the engine coil (+) is electrically charged
Yes Go to next step
No Check the wire harness between ignition switch ignition coil and ECM
4 Check if resistance of ignition coil is OK
Resistance
Primary : 0.36~0.44Ω (at 68°F (20°C))
Secondary : 10.9~13.3kΩ (at 68°F (20°C)) Yes Go to next step
No Replace
5 Check if ECM is OK Yes
No Replace
REMOVAL
Do not attempt any maintenance on spark plug if engine is hot.
1. Disconnect negative battery terminal.
2. Carefully remove high-tension leads.
3. Use compressed air to blow any dirt or debris from around spark plug hole.
4. Check that spark plug fits squarely in spark plug socket and remove spark plug.
Raise a vehicle and install SST(OK552 131 001) in order to replace cylinder 2, 4, 6 spark plug.
hey i actually just dealt with this problem last week ona friends car. the oil in the center with the spark plugs is because you need a new valve gasket. not a cover unless its cracked just the gasket and it costs about 25 dollars at your local parts store. its very easy to install and a quick fix but try to get all the oil out of the center as you can and rub a little bit of old oil on the gasket before you install it. it helps stop dry rot. try this first and then see if the backfiring and stalling stops. if not, you may need to change your spark plugs again even if you already have because chances are the oil thats already in the hole has burned up the spark plug. so give your spark plugs a good check while you change your valve gasket.
