So I encountered a weird issue with a 93 Leg the other day.
Won't start, voltage kinda low, but engine cranks fine. (brand new battery and alt) HAs the "hollow" cranking sound of a timing belt off a few teeth. Reset belt, it was 1 tooth off, probably installed wrong, not slipped......not the problem.
Hmmm......I check electrical a bit. Turn key on. CEL lights for 1/2 sec. then goes out. Will not go into test or read mode.
Swap Ig. relay, no change, Clean connection of Fusible link supplying voltage to the IG. relay, no change. Battery starts getting really low, so we hook up cables.
Let it charge for a while. Try again, now CEL lights, almost steady....or at least more so. But still is blinking on/off randomnly (not in test mode, not code flashes, I know what those are).
Try to start......struggles, but eventually catches, and starts. Now before it started, the cranking sound went back to a normal cachuga-chuga and fired. Shut it down and try to start again.....now cranks hollow won't start, no CEL again. I think ECU cuts out fuel and spark signal.
Try a few more times......Back to sounding good, CEL lights (but still is sketching out), Fires up good. Has fired up each time since.
My question is, has anyone seen an ECU fail like this. I've seen them fail to light the CEL at all, but never seen it trip out like this. Going to try a new ECU in the car and see what we get today. I'll take video of the CEL.
Just thought I'd ask the community. Thanks.
