TIMING PROBLEM 96 LS 400 After replace timing belt. knocking sound on left hand side engine, cold start in the morning, missed fire on # 3 cylinder Help Help...........................................

NO YEAR TOLD... 1993 TO 1996?
CORRECT NAME (NO SPACE BEFORE C)
Hyundai Scoupe? ALL 4 BANGERS ARE 1,3,4,2
EXCEPT BOXER ENGINES (PANCAKE MOTORS)
IS THIS A SPARK QUESTION?
OR CAM TIMING QUESTION.?

• • 1.5L Sirius I4
  • 1.5L Alpha I4
  • 1.5L Alpha Turbo I4

Yes, that may cause it the misalignment of the timing belt, you can try to check it and put everything back in..

Good luck.........

firing order is 1-2-3-4-5-6

the #1 cylinder is the one closest to the timing belt on the back side. #2 is closest to the timing belt on the front side

Sounds like a bad coil. i would swap the coils to run 2,4,6,and 8 and see if those started to misfire. If 1,3,5,7 still misfire I would do a compression test. Has the timing belt been replaced yet.

knocking is a big thing, its a cry for help.
can be minor to horrific
knocking parked? or only driving.
in neutal or park?
knocking hot block, or cold block or both? at what RPM>/
only real oil pressure gauge works, not the idiot lamp
when the lamp comes on at 3-5psi, the war was lost.
my 96 makes 55psi cold just cranking, want a video of that?
find the knocking first.

if can ,be knocked , parked.?
id check oil pressure. real.
use a $5 stethoscope. find it.
drop all belts. to see if an accessory device knocks. (5min test max cold to start, yes, water pump dead)
PS/AC/ALT dead too.
still knock>
listen at valve cover. coming from there.
is the timing belt is old over 60k thy all shard and some knock load hitting that cover, it a for sure thing, skipping the 60k mile service point,
exhast header collerctor fange gasket , bad, allowing bang band bang as the 2 flanges pound themselves to death.
the top of the engine, see induction pips. (AIR) those mounts for sure can bang away, bolts missing.

knocking:
1 overheated the engine so bad its pinging? knocks up hills?
2: say exaclty when and not you get the knocks.

CHECK FOR SPARK AND FUEL.IF ALL IS GOOD A BAD COLD START VALVE WILL CAUSE COLD ENGINE START UP PROBLEMS COLD START VALVE DOES SAME JOB AS ENGINE COOLANT TEMPERATURE SENSOR IT ENRICHEN FUEL SYSTEM FOR COLD START UPS. DO LITTLE TUNE UP MAKE SURE SPARK PLUGS AND WIRES GOOD, REPLACE DISTRIBUTOR CAP AND ROTOR,CHECK IGNITION TIMING, REPLACE AIR FILTER AND FUEL FILTER. IF CAR GETTING FUEL AND SPARK.CAR TIMING BELT COULD HAVE JUMP TIMING IF TIMING BELT NEVER BEEN SERVICED OR REPLACED.

a miss fire would mean a bad coil for #6
if you have a coil pack all with all 6 plug wires need to replace it.
if your coil pack has 3 or 4 coils need to replace just the one with # 6 plug
wire in it. most have 2 plugs per coil.

3.0L Engine

1. Before servicing the vehicle, refer to the precautions section.
2. Disconnect the negative battery cable.
3. Drain the engine coolant.
4. Remove or disconnect the following:
   Wiper and blade assembly Top cowl seal and panel Window washer hoses, from the ventilator louvers Left and right ventilator louvers Heater air duct Timing belt
5. Mark the left and right camshaft pulleys with a touch of paint.
6. Remove or disconnect the following:
   NOTE Be sure not to mix up the pulleys.
   Right and left camshaft pulleys bolts Pulleys from the engine
   No. 2 idler pulley by removing the bolt 3 clamps and engine wire from the rear timing belt cover 6 No. 3 timing belt cover-to-engine bolts Water pump nuts/bolts Water pump and gasket from the engine

To install:

1. Check that the water pump turns smoothly. Also check the air hole for coolant leakage.
2. Apply liquid sealer to the gasket, water pump and engine block.
3. Install or connect the following:
   NOTE After tightening the bolt, be sure the idler pulley moves smoothly.
   NOTE Be sure to align the knock pin hole on the camshaft pulley with the knock pin on the camshaft.
   NOTE Be sure to align the knock pin hole on the camshaft pulley with the knock pin on the camshaft.
   Water pump, using a new gasket. Tighten the nuts/bolts to 53 inch lbs. (6 Nm). Rear timing belt cover. Tighten the 6 bolts to 74 inch lbs. (9 Nm). Engine wire with the 3 clamps to the rear timing belt cover No. 2 idler pulley. Tighten the bolt to 32 ft. lbs. (43 Nm).
   Right-hand camshaft pulley, with the flange side outward.
   Tighten the camshaft bolt to 65 ft. lbs. (88 Nm), using the removal tools Left-hand camshaft pulley, with the flange side inward.
