Do you know what the engine came out of ???

 

Ok will do and yes I know a 4.7 came out of it but not sure of year of motor that was put in I will get the numbers and Vin and give them a call

 

Just the year model. Unplug the cam sensor and see if it runs any better. You will have to crank for 7 seconds or so before it will start.

 

Ok guys I unplugged the cam sensor and cranked it never even hit, also I got the casting number 53020661a-3 and called the dealer and they said I will need the Vin stamped on the block but I can't find any other numbers. Is there a website I can use to find the year off the casting?

 

Is there a chance this motor could have the 12 tooth ring gear instead of the 32 tooth? Would it still run on the 3 cylinders it is running on if so?

 

That rules out the wrong computer/ring gear combo in my mind. I would do a compression test next to rule out some things. We can get a clue if it's mechanical timing issue or not. If I had a scan tool on it live, I could get there quicker, but this is the way forward in this case.




Tell me again what makes you think you're running on 3 cylinders.

 

I Went through and unplugged coils why running and on my computer it's showing spark adv -64 but then agin it's still throwing the crankshaft code so idk I will get compression this evening after work on all 8 if there not washed out with gas after running it yesterday

 

Ok got the compression on all 8 . 160-1. 0-3. 105-5. 160-7. 160-2. 160-4. 165-6 160-8. I will have to dig in to number 3 and see what is going on maybe stuck valve are broke spring??? And number 5 is very low but that is 1 of the 3 that it is running on

 

That spark advance data is bogus on my data list and it has no effect on anything. It's called Base Spark on mine. You want to look at Cam/Crank difference and long/short term adaptives. I would pull a valve cover and inspect.

 

Ok does it have to be running, and veiw on live data to do that?
