1992 GMAC Van will not start!

First, Van died while driving. Plugs were replaced, and valve in TBI. Van ran for 1wk. Now it is dead, will not start. Changed Fuel pump filter, Distrib cap, rotor, elec mode, and am now replacing magnetic pick-up coil. No spark! 6 cyl 4.3l electroinc fuel inj. When I removed dis cap, I see rotor move when cranked. Please advise. Thank You - CLI

If you haven’t checked the fuses yet then do that. Also verify power is getting to the ignition system using a test light or meter. Also check the ECU for any stored codes that may help with this trouble.
