You most likely have a pressurized fuel leak in the fuel injector/regulator assembly that is located under the upper intake manifold. There is no way to fix this except to replace the entire unit which is around a grand or so, might have come down in price. This is not a hard job as the upper intake is dry. There are just bolts, sensor connections, some intake pipes and plenums to take off to access the injector assembly. To be sure this is the problem, simply shut the motor off and wait about ten minutes. Then unscrew the fuel pressure tap located on the left rear of the motor close to the distributor and depress the valve, it looks like a tire valve, and if the fuel just dribbles out that will be the problem. These should hold about 55 psi of pressure at shut off. Good luck.

My wife just went throught this with a 94 Blazer. It's the spider web injector. The spider web is made of plastic, over time it cracks and breaks and starts dumping to much gas into the cylinder. It cost about $700 at a local garage. The spider is about $300 plus other necessary parts. It maybe worth it though. My wifes blazer has more power now than a new one

3 issues your engine needs to run. a million. Compression. could could positioned a compression tester in this and notice in case you have good compression on all cylinders. 2 gasoline. you are able to properly be getting it to three cylinders, yet one or 2 undesirable injectors could reason it to no longer start up. 3. fire. examine to ascertain which you have spark on the plugs. in case you have all 3 of those, it is going to run. There are no longer any exceptions to this rule. in case you have all 3, it is going to run. won't run great by way of different subject concerns, even though it is going to run.
