Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hi, I am Mike, welcome. I'm reviewing your question.
Simple test. See if the engine will start up and run for a few seconds after spraying a few small shots of starting fluid into the throttle body then quickly turning the key to start. If it does start and run for a few seconds then the problem is with the fuel system, so make sure the fuel pump runs for the first 2 seconds the key is turned to start and if so, check the fuel injector fuse/s and if they are fine, check for a crankshaft position sensor trouble code. If it doesn't start with the starting fluid, then most likely you have no spark, so check the ignition fuses and again check for trouble codes.
I see both engines are a vin 7, so that should not be a problem.
If there is a theft or security light on flashing, try another key or clean off that key and try again.
That is the engine vin, or the 8th digit of the vehicle that engine came in.
Buy a $3 can of starting fluid and try it before calling the tow truck.
I know it's the same.
He may have checked fuel pressure but what about fuel injectors actually working?
Was this a running 2006 engine?
try the starting fluid and let me know what happens
Did it start with starting fluid or not?
And if it is getting a spark, about the only thing left is the timing of the spark or the firing order. Unless all the spark plugs are fouled.
If that were true, you would not have a spark.
You had better go take the car somewhere else.
It doesn't have to be the dealer.
You opened this post by saying "Yes both are getting fuel and spark" not you want to change your mind and say, " no spark"? Why?
You just asked "So if theres no spark then what could be the problem" and at first you said, ""Yes both are getting fuel and spark" So why not are you asking what it could be if there is no spark if you already confirmed there is a spark?
I don't know what his blue light test was. I don't know how much more I can help if any at all unless I can text, talk directly with your mechanic.
Don't forget to rate me well, so I get credit. If you don't, the deposit you made will just sit there and I won't get my share of it.
