Cylinder seven misfire

Verify that you can feel the injector clicking. If it does not click, with a noid light verify that it flashes while the engine is running. Also verify that there is sufficient compression on that cylinder and compare it to a known good cylinder.

Welcome to 2CarPros.

What I want you to try is this. Switch the number 7 coil with another one and see if the misfire changes cylinder. If it does, then replace the coil. If it doesn't, then I want you to follow the the link below to check for a pulse to the injector:

If the injector is good, you have to check compression. Here is a link that shows how to check compression:

Here are the specific directions for testing compression. The attached pics show the acceptable range for compression.

Compression Test - Compression Gauge Check
1. Make sure the oil in the crankcase is of the correct viscosity and at the correct level and that the battery is correctly charged. Operate the vehicle until the engine is at normal operating temperature. Turn the ignition switch to the OFF position, then remove all the spark plugs.
2. Set the throttle plates in the wide-open position.
3. Install a compression gauge such as the Compression Tester in the No. 1 cylinder.
4. Install an auxiliary starter switch in the starting circuit. With the ignition switch in the OFF position, and using the auxiliary starter switch, crank the engine a minimum of five compression strokes and record the highest reading. Note the approximate number of compression strokes required to obtain the highest reading.
5. Repeat the test on each cylinder, cranking the engine approximately the same number of compression strokes.

Compression Test - Test Results
The indicated compression pressures are considered within specification if the lowest reading cylinder is at least 75 percent of the highest reading. Refer to the Compression Pressure Limit Chart.

If one or more cylinders reads low, squirt approximately one tablespoon of engine oil on top of the pistons in the low-reading cylinders. Repeat the compression pressure check on these cylinders.

Compression Test - Interpreting Compression Readings
1. If compression improves considerably, piston rings are faulty.
2. If compression does not improve. valves are sticking or seating incorrectly.
3. If two adjacent cylinders indicate low compression pressures and squirting oil on each piston does not increase compression, the head gasket may be leaking between cylinders. Engine oil or coolant in cylinders could result from this condition. Use the Compression Pressure Limit Chart when checking cylinder compression so that the lowest reading is within 75 percent of the highest reading.

If the cylinder has spark, fuel, and compression, it has to fire. One of these thing is the problem. Check these things and let me know what you find.
