Got a 93 chevy suburban, this morning was on my way to church and it was running rough, then as time prgressed it got worse finally it died at a red light. Pulled off air cleaner had wife turn ign, no fuel. Listened for fuel pump at rear of car was buzzing. Went to the store got some starting fluid and it started. Tried to make it home died again. This time starting fluid didn't work. Towed it home pulled spark plug it has spark. Pulled fuel filter cleaned and got fuel back still will not start think it could be ecm? Or what do you think?

It wouldn't surprise me if the igniter is also bad ($45, AutoZone), just like on your Honda. Super easy to replace on your Suburban, however. It may be switching current on and off to the coil at the wrong time, even though the plugs still fire. Likely, it's a variation of what happened to your Honda, assuming you are getting fuel and the CEL does not stay on. If the igniter was firing when it was supposed to, the truck should have started the second time with starter fluid. Therefore, I discount that it's a fuel problem.

Did you actually replace the fuel filter, however? It was unclear.
