Question about 1990 Oldsmobile Cutlass Supreme Conv
My 1990 Oldsmobile Cutlass Supreme died one day and just one start now. I have replaced the coils, the computer, timing chain and gears. Checked the plugs and wires. Theres no power to the Crankshaft sensor. And when we unhook the antiknock sensor, we get a code on the code reader. But, when we unhook the crankshaft sensor, it finds no codes. We can clear the code, but it still won't run. Yes, it has gas in it and we checked to make sure it was getting gas. Any ideas?
I have some experience with my oldie cutlass 90 that I had import to my farest country : CHILE .
My car seemed to run in three cylinders , of 4 .then started to run good in cold and after 10 minutes stop and die for a long time ...a few days after strat again and dies and so .. I studied about I read about the prom I learnt all abo¡ut this kind of irregular fails that even experiencied machanics can´t solve ...( It took 6 months and seven mechs to solve )..
the cars falls in limp in mode ( a kinda mem programmed mode for a few minutes and everybody thinks it the crankshft sensor , the ignition module , the ecu fial etc simply is code 51 : mem cal fail and limp in state i suggest work with and a code reader and it could be that kind of irregular fail..
ah. it´s too hard to find the eprom so the ECU dealer usually sell it without the eprom .. mine is ANLP 3645 ) federal emission .if you know when can I buy this or a good used one . I ´d shop it again cause I don´t want suffer about it again.. luck
