Re: Intermittent hard crank/no start problem (Not Passlock)
Thanks to all for the continued help and advice. The check engine light is on when I'm in the crank-no start mode. I'm not checking anything because the car routinely fails when I'm on the road and starts after waiting 15 minutes and, further, because I'm not competent to do some of the electrical checks being suggested. It did it again this morning, same sequence: short 5 minute drive, 45 minutes time elapses, then crank-no start (check engine light on), then rest 15 minutes, and it starts. I've taken it in 4 times to mechanics who cannot duplicate the problem. So, yes, from my long list of repairs in my first post, to my last effort with the ignition switch, I'm making the best educated guesses I can and, thus far, most the work has been necessary, i.e., I needed the ignition lock cyclinder to deal with the passlock issue, it needed the new fuel filter, spark plug wires, etc., because of 140K maintenance, the oil pressure sender was bad, etc. The ignition switch probably was unnecessary as it turns out, but, as was suggested, it had a high probability of success. I'm very frustrated because I have no confidence in the shops around here to duplicate the issue much less repair it and I only have a 15 minute window to diagnose everytime it does fail, even if I was competent to diagnose.
