I'm not too worried about the glow plug relay, since it's a relatively cheap fix, but from a conceptual view...
My '82 has push-button glow plug activation. Recently, I'd bend down to press the glow plug light, hear the relay *POP* (or *THONK*, *PANG*, whatever sound effect you want to use) but the "glow plug" light on the dash wouldn't illuminate for a couple of seconds. Then, the light would show and the truck would start.
This past week after being out of town, I hit the push-button, hear the *POP* and NO "glow plug" dashlight...plus, the truck would turn over but not start.
Tonight, after seeing the thread on using jumper cables to bypass the relay, the "glow plug" light immediately came on and the truck fired off triumphantly.
MY QUESTION IS...why would I hear that heavy-duty *POP* without the glow plug relay working? Does the jumper cable trick bypass the relay, or my manual push-button switch? Is a new glow plug relay needed?
