1994 Lexus GS 300 Repair Question
Why will car just stop running for no apparent reason, while running, at idle, or in gear at a stop light etc.
Changed fuel filter on chassy by lt rear wheel. Car started, ran for 10 to 15 min. died. Listened to fuel pump sounded like not running all the time,,
seemed to sound strange.. Noticed car giving off strange odor each time it did run. Pulled fuel tank,, installed new denso fuel pump kit.
put in fresh fuel.. disconnected battery.. let set 20 to 30 min. reconnected. Car started ran great... lit sit and idle.. and in 13 min. car died again... car giving off strange ordor from exhaust.. (looking at changing fuel regulator next) checked 20A EFI fues, also switched out EFI relay to see if it was shutting off pump. Does not seem to be the issue.
any codes present?

no, jumped the te1 to the e1 with key on the injecters were clicking so much that the check engine light flickered so iratically that you could not tell what was a flash and what was not at flash. after about 4 or 5 min. all the clicking of the injectors stopped, then the check engine light shinned steady.. no flasking nothing but steady... disconnected the battery.. tried it all over.. no irratic injecter issue, no flashing and pausing of the engine light.. car does not try and start at all now...
when it was tryin to start,, I had fire and plenty of fuel.. still would not try to start ..... having towed to a shop tomorrow...

Start at the catalytic converter, if it's c;ogged, the car will not breathe, and will not run, remove an O2 sensor b4 the cat and see if it will start. or drop the exhaust and do same.
