Question Random no start usually after sitting overnight

Hi new to the forum

2004 Ex Limited 148K miles

Has a random no start every few weeks or months.

The last time it happen I went and purchased a SG II so I could get some vitals

KOEO FICM is 48; cranking 48
FLP is 12
IPR% is 30-40 range
IPC is 800-900 range
KOEO Fuel pressure is 62psi has blue sprink upgrade
Sync is 0 Should this read 1 while cranking?
FICM sync is 0 Should this read 1 while cranking?
Fuel tank at 1/2
Oil pressure gauge shows pressure after several seconds cranking.


I can get it started with alternative fuel and it runs fine and most likely will not happen again for weeks or months

Any ideas??

Well the Ex must have found out I was rating it out on this forum, just stranded my wife 40 miles from home. No fun!
had to use alternative fuel to start. Almost like the pcm has to see higher rpm 's to start. Having batteries checked Manana

Batteries checked out good. Started everytime yesterday. Which is good on one hand but as Murphy will have it. Next no start will probably be away from home...

The ficm should be syncing, ficm wont turn on until it knows where the crank and cam are.

Check the wiring to both,wiggle around and look for chafing.

Does the scanguage update fast enough to show sync before it starts? The reas on I ask is that by the time I see sync its started. Of course if no start I never see sync.

Yea it is a slow processor for sure but it will show no sync like you are seeing. Check the harness and pigtails. Your problem is there somewhere.

Intermittent faults are a pain to find. Worse when they leave you on the side of the road. Are there any soft or hard codes? Check next time before you go to start it again.

Had the no start happen again today

So when I start with wd-40/brake kleen, what does that do to make it run fine for weeks at a time. Is the higher rpm during the start overcoming a fault in the cmp sensor?

Seems if it was a short or something or bad sensor, it would still be shorted out or a bad sensor regardless of whether its starting on diesel or wd-40

Its seems the higher rpms of a juiced start cause the computer to allow the injectors to operate?

So what you are saying is all the start parameters are being met, except the sync is not happening except when you aid the start, intermittently, correct?

Are you showing rpm when it cranks but doesn't start? This will distinguish between CKP and CMP sensors for establishing sync. It is quite possible you have a weak CMP sensor. Often this is caused by corrosion at the plug that can migrate into the sensor. The CMP sensor can work once for a start sync and then it can fail and the engine will continue to operate normally until the next start. If it is an intermittent problem it can behave like your problem. The CKP is different, it has to remain in sync or the engine will quit.

Ok thanks for the reply. Starting to make more sense now. I didn't realize that the engine would run without the CMP sensor. I will check that sensore out.
