It's getting fuel and spark. Here's a question for you. It was running really rough because the egr was stuck open and the mechanic that was working on it blocked it off and said I didn't need it because there is no emissions here. Could that cause the no start?

Good luck with that plan. 87 and up DIS engines often will have problems w/o good EGR.
Why? GM programed DIS ECM to assume a good EGR or engine can, likely will, knock.
I took off the egr and it didn't look like it was blocked off at all, but he said he did and that fixed the previous problem of shaking with low acceleration. Also I cannot find where he put the vaccum line running off the egr.
If the mechanic removed the vac line the EGR solenoid will have an open connection.
There's no EGR solenoid on the 4-cylinder. Also, the EGR can't be tested by applying vacuum to the vacuum line fitting on it. The only way to test the EGR on a 4-cylinder is to run the engine, slowly increase RPM's, and see if the diaphragm in the EGR valve rises. It is controlled by a combination of vacuum and back pressure, and neither alone can open it.
How do you know fuel is getting to the injector? Did you remove it? If you remove it right after an attempt to start, you should get quite a squirt of gas (in your face if you're hovering over the throttle body).
Relay is good, just tried starting fluid with no effect. Starting to think the injector is actually good, but I didn't see fuel coming out when cranking it and I do believe a cone of fuel is suppose to come out. Also retested the spark and there is none. Ignition module is good, coils, plugs and wires I just replaced. Any thoughts on to what else will cause no spark?
