2.5 Injector issue

As of late my 88 2.5 has has a couple of sluggish moments so Ive been exploring my fuel systems issues. It was running prior to this but I'd read somewhere to remove the injector and check the screen for debris. After I checked the spring I put my injector back in but it seems to be spraying fuel out the top a bit and refuses to start. It started a few times in a row today before I ever touched the injector so in pretty sure something went wrong there.

Any ideas?

It sounds like youscrewed up the injector some how. Here are links to the FSM.

Here is a link to Shaef's tbi rebuild:

The 87-90 TBI all have a renix controller and several adjustments. You wil need a meter to do them. Sluggish moments migh be an issue with the O2 sensor. First things first, look at the threads and try and get it going.

Thanks for the help. It ended up being the larger on-ring on the injector. I didn't know it was supposed to be there but I saw it in he FSM. Couldn't find the on I had lost so I went to the parts store and picked up a variety till I found one that worked. I then pulled the fuel pump relay and purged the gas that had flooded into the intake. Turned it over till it started and then put the relay back in. Its running again but I'm back to square one so i bought a TBI rebuild kit and a fuel filter. I'm hoping I'm narrowing down the issue.
