check your compression on #4 cyl
if a cylinder is not firing there will be no spark at the spark plug. Carefully twist as you pull the ignition wire out and start the engine. when the wire gets close to the spark plug you should see an arc. This means the cylinder is firing
There are several possible firing orders of a six cylinder engine, in practice however, mostly it is 1-5-3-6-2-4. The ignition interval is also at 120 degrees.
The ignition coil packs have the cylinder numbers listed on them. The cylinder closest to front of engine (where serpentine belt is) is cylinder #1, the odd cylinders are on this side of engine. Cylinders are in order from front of engine, ignition coil wires display their positions of which cylinder they belong to.
The firing order for a 1988 Mazda E2000, which features a four-cylinder engine, is 1-3-4-2. This means that the ignition sequence starts with cylinder 1, followed by cylinder 3, then cylinder 4, and finally cylinder 2. Proper understanding of the firing order is crucial for engine timing and performance.
The firing order of a 1947 Plymouth 6-cylinder engine is 1-5-3-6-2-4. This sequence ensures that the engine runs smoothly and efficiently, with each cylinder firing in a specific order to maintain balance and power. It's important to follow this firing order when setting up ignition timing or replacing spark plugs.
The firing order for the 2001 Hyundai Accent with a 1.5-liter engine is 1-3-4-2. This means that the ignition sequence starts with cylinder 1, followed by cylinder 3, then cylinder 4, and finally cylinder 2. Properly following this firing order is crucial for the engine's optimal performance and smooth operation.
try changing your spark plugs if theres any.

The firing order for a 1989 Chevrolet Corsica with a 2.2L engine is 1-3-4-2. This sequence indicates the order in which the cylinders fire, starting with cylinder 1. The engine has a four-cylinder configuration, and understanding this firing order is important for proper ignition timing and engine performance.
The firing order for the 1999 Hyundai Elantra with the J2 engine is 1-3-4-2. This means that cylinder 1 fires first, followed by cylinder 3, then cylinder 4, and finally cylinder 2. It’s important to ensure that the ignition system and timing are set correctly according to this firing order for optimal engine performance.
The firing order for a Mazda 626 4-cylinder 2.0-liter gas engine is 1-3-4-2. This sequence ensures that each cylinder fires in the correct order to maintain smooth engine operation and efficiency. It's important to follow this firing order when setting up ignition timing or troubleshooting engine performance issues.
To check if cylinders are firing, you can use an ignition timing light or a cylinder compression tester. With an ignition timing light, you can observe the flash of the light at the spark plug wire to see if it is firing. A compression tester will measure the pressure in each cylinder; if a cylinder has low or no compression, it may not be firing properly. Additionally, you can visually inspect spark plugs for wear or fouling and listen for engine vibrations or misfires while running.
