Question about 1997 Oldsmobile Cutlass Supreme
Ran fine with no obvious issues, then stopped running. Restarted, but it ran real fast, and gave all appearance of being out of time. Replaced timing chain making sure #1 was at top dead center. Will now start after it sits for awhile, but won't start a second time, and when it does start, it is out of time.
getting spark at the 3 coils.
Any suggestions on what I could check next?

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

ENGINE STALL DUE TO FUEL STARVATION: Fuel System, Gasoline**
no recall issued
** This defect investigation is filed under 4 related vehicle components.
2000 OLDSMOBILE ALERO -- ODI opened PE02-066 to evaluate the scope and consequence of engine power-loss due to fuel starvation induced by in-tank modular fuel pump strainer restriction.the subject pumps use an external ?sock? strainer to filter fuel flowing to the pump inlet.this filter can sometimes become clogged, resulting in a reduced flow of fuel to the engine.GM has subsequently modified the strainers to reduce this restriction.analysis of the ODI complaint database shows that despite these restrictions, the subject vehicles stall at a rate that is comparable to those of many peer vehicles.additionally, none of the relevant warranty repair rates exceed 1% at 36 months of exposure.one related crash involves a stalled vehicle that was rear-ended on the roadway, while the remainder involved minor collisions or scrapes.the sole injury consisted of bruising from a low speed frontal crash. Given these circumstances, further expenditure of Agency resources is not justified in this matter.the preliminary evaluation is therefore closed.the closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists.the Agency will take further action in the future if warranted. Investigation was initiated on September 06 2002. Closed on November 03 2003. For detailed information & supporting documents, see the official

If the engine won't start, perform a spark test as described earlier. This will narrow the problem area down considerably. If no spark occurs, check for the presence of normal battery voltage at the battery terminal (BAT) in the distributor cap. The ignition switch must be in the on position for this test. Either a voltmeter or a test light may be used for this test. Connect the test light wire to ground and the probe end at the BAT terminal at the distributor. If the light comes on, you have voltage to the distributor. If the light fails to come on, this indicates an open circuit in the ignition primary wiring leading to the distributor. In this case, you will have to check wiring continuity back to the ignition switch using a test light. If there is battery voltage at the BAT terminal, but no spark at the plugs, then the problem lies within the distributor assembly.
If the trouble has been narrowed down to the units within the distributor, the following tests can help pinpoint the defective component. An ohmmeter with both high and low ranges should be used. These tests are made with the cap assembly removed. and the battery wire disconnected. If a tachometer is connected to the TACH terminal, disconnect it before making these tests.
