1990 lebaron won't start

My lebaron will turn over, according to the repair shop it has spark, the injectors are putting in fuel, it is getting spark, and the timing belt is fine and everything lines up. However, it won't start. The computer says everything is working, and it doesn't show a problem with self diagnostics.

make sure your air filter is clean and all hoses/tubes from your air filter going to your intake manifold are free of restrictions. Ask them what color is the spark when they tested it? Was it bright & blue in color or weak & distorted? Also, have a compression test done on your engine, make sure it still can make compression to turn it over.

use a spark tester on the coil and test the spark output at the coil. do not use just a spark plug. So the injectors are good but is there fuel getting to the injectors, check to make sure that you can hear the fuel pump running. Also, compression test the engine.
