Cranking no start after work

95 f250 5.8

so the platform that the vacuum lines and electrical connections sit on broke and I found it on the valve covers. Still running fine. So I disconnected everything and welded the bracket and hooked everything back up just as it was. Green over white and red over black on the vacuum and the electrical connections clicked and are tight. Can somebody steer me in the right direction as to why I’m getting a crank no start situation?

thanks in advance, my thought was no vacuum because the vacuum sucked for a bit when disconnected but I figured that would build back up

Is that green one connected to the EGR valve? Or the white one? There should be no vac going to EGR at idle

It may, it goes into the bundle and may go over to the passenger side. I’m not sure. I know that’s where it was and not I have nothing

Could I have fried this thing when I welded? It was very low heat and less than an inch of welding

Weld on a computer controlled vehicle (especially old) with bat &/or ECU connected... very, very bad idea.

Check for spark, voltage at coil-key on/engine off, resistance on coil-etc?

Have spark, tried starting fluid?

Don't forget to check the EGR, pull the vacuum off the valve, and try to start it

No spark which leads me to believe it’s that ignition coil
