Have a 90 7.3 idi. Bone stock. My glowplugs were fouled out so I replaced them, system seemed to work fine before replacing just weak. Since replacing, the plugs will kick in for about 20 seconds, then click on and off rapidly for a minute or so and the cylinders are not warm enough to start. I replaced the plugs(diesel rx) , relay, and all of the gp boots. What do I need to look into next.
