What does the rapidly flashing CEL mean? - SC300
Newest scenario:
Bloody car still does not start. However, 93MSB correctly asserted E1 and TE1 were connected or shorted somewhere and they were: I had them jumpered under the dash at DTC2 and had, apparently, put the cover back on while installing either the new dash cluster or the new climate control unit. In either case, this is something I did to myself!
BTW, this was during my "Car Won't Start" crisis. FINALLY - won't start - RESOLVED
--------------------------------------------------------------------------------
Thanks to 93MBS, MegaMax and all of the incredibly helpful members!
I parked my 1993 SC300 in the garage one night and the next morning it would not start. It tried to run once and it continued to turn over nicely but it would not catch.
After checking the obvious, then replacing the ECU ...drum roll...it turned out the timing belt had slipped! Now, this is a new high end timing belt and there really is no excuse but that is what happened.
I did not need the new MAF, ECU. I returned the NOID injector test lights.The upside? The timing is spot on, the valve clearance is perfect, the fuel has never been cleaner or the octane higher, and the platinum plugs, high tension wires, distributor cap, rotor, PCV, etc. will not need to be replaced again for a long time. I am outta the garage!
Kind regards,
Wade

O it flashes while your trying to start it. That is very weird, I have never came across that. Only time there was a issue with a light and it wouldn't start was cause the ECU was bad. But thats on a DSM not a lexus.

my guess is bad ecu, I had somewhat similar symptoms when the ecu went out on my supra. like the check engine would come on but it wouldn't have any codes stored. sometimes it would start and sometimes it wouldn't
open up the ecu and look for leaking capacitors

93MSB - I ordered an ECU from a fellow forum member. It should be here next weekend. I could not find one for the CA emissions. Is that going to be a huge issue once I have her running again? I settled for the 89661-24312 (49 states) instead of the 24332.
