Maybe it was a weak battery causing the long start time, all along.

The "weak battery" hypothesis got me to wondering. The Purple 95 takes considerably longer to start than my Turq car. The Turq car has an Optima battery purchased last year.

I just checked the battery in the 95 and it's the original. Having only 9k, I suspect that it's most likely been on a battery tender most of its life.

I'm wondering how sensitive these cars are to old batteries. I know the vipers are known to being sensitive. ---

Things that make you go Hmmmm....!

Just thinking out loud (uh, oh...) I suppose because I've not had a hard starting problem (knock on wood), that I assumed the starter itself wouldn't engage if the voltage durring crankin dropped below a certain threashold (compared to an AC/Delco vis a vis a SBC) - and maybe that IS also true as well.

But, now my curiosity is piqued: there may be other things e.g., fuel, spark, that could be affected even IF the starter is rolling the engine over. It would be interesting to know what that threashold voltage is, if that is the case.

Hmmmmm.....

Paul, I don't know if my injectors are the originals. I'd bet .50 cents that they are. The starter may just turn a little slower??????

Anyway, it starts. Just cranks a little longer than my Turq car that has the Optima.

If I end up putting an Optima in the car, I guess I'll find out if it changes.
