If the engine inst running the check engine light should be on. It sounds like the fuel pump has gone out. Can we do a pressure test?

I just replaced the fuel filter and I've never seen fuel so dark. It was very hard to blow through the filter. How do I get my vehicle running now.

If that was the first time the fuel filter was changed then that would explain the dark fuel and restricted filter. See if you have spark and see what the actual fuel pressure is. Also see if you are getting a injector pluse you would unplug the injectors and plug in a noid light where the injector went. Then crank the engine over and see if the light flashes. The light should flash while cranking it shouldnt stay on solid. Check all the injector connectors.

Thanks for the help. I just got the van to start using starting fluid. But it runs for a few seconds then dies. The check engine light has turned off. I just dont think it is getting fuel now. Could a fuse be the problem?

Check power to the injector fuse and fuel pump fuse on the fuse panel under below the glove box. That they show good and that u hear the pump turn on.

If it was the security or the car would not even crank. This hast to be a fuel problem. Rent a pressure tester from the parts store. Turn the key on and read the pressure then do a leak down test turn the key off. Come back in 15 mins. The gauge should read the same

I just double checked and the fuel injectors are disabled not the starter. You can look for yourself if you like on the earlier gm cars the starters were disabled. The later gm cars they started disabling the injectors. So you will get a crank no start so if the security light is coming on and you have a crank and no start I would start with diagnosing that.
