Hi everyone. I have an Eldorado with intermittent ignition issues. Sometimes when attempting to start, I turn the key and get no cranking. However all the rest of the car powers up, air, radio, gauges, Ect. After many attempts at starting, it will eventually cranks and fire up smoothly. I have not found the secret as to why it only does this. Help!

Re: 2001 Eldorado ignition problems
Just above this post is a thread "How to pull codes". Study your car's section for how to get trouble codes from the car's built-in scanner memory. Pull your codes, write them all down whether each is Current or History. Return to the sticky to open the link with "obd2" in the address. Decipher all your P, B, C, and U codes and post them all here.
Definitions? Not sure what you mean. Is there a way to pause the codes as they scroll thru? Some say: history, with a code.
If the 2001 Eldorado follows the same procedure as the 1998 Seville, you can review each category of codes individually (such as all PCM codes), but you can't scroll or pause within the category.
What you described is exactly what happened to me when my starter was going bad. Apparently there are "bad spots" in the starter, and each time you try to start it, it turns a little bit until it finally lands on a "good spot" and starts.
no sounds at all, i will have to check on the voltage.
What i found so far:
RFA-U1064-history = loss of communicatios with DIM
PZM-B0533-current = fuel sensor open/shorted to B+
PZM-B1558-history = BCM EPROM checksum error
MSM-B2120-history = Lumbar up/dowm sensor fail
PCM-B1552-history = keep alive memory
PCM-P0340-history = Camshaft Position Sensor circuit (CMP)
A quick update on the intermittent starting on my 2001 Eldorado. I took it to a reputable mechanic and dropped it off on a Sunday eve. When he went out on Monday morning to bring it into his shop. No ignition! So he manages to get it into his shop somehow and gets his equipment connected. From that time forward, flawless starting. Figures. Anyway he said his gut feeling would be the starter. So I had him replace it and its been fine ever since. Not one failure. And also he bypassed the security key diode to eliminate that possibility. Thanks for your input and maybe this will help someone else with a similar case.
