Hi there. Welcome to our site!

PLEASE READ THIS FIRST:

If you’re thinking on working on the vehicle yourself, all my knowledge and resources won’t help unless you…

… have basic mechanical knowledge and skills, and…

… have whatever tools and equipment might be needed for a proper diagnosis

----------------------------------------------------------------------------------------------------------------------------------

First things we would need to check are fuel pressure, spark and injector pulse as anyone of those would prevent the engine from starting if faulty. Are you able to do those checks?

Customer reply replied 2 years ago
I could check those , I would need a gauge , is it possible to check fuel pressure with our engine running ?
Cadillac Mechanic: Juan Crespo, ASE Certified Technician replied 2 years ago

To check fuel pressure, first connect your pressure tester then crank the engine. The onboard computer will turn on the fuel pump for a couple of seconds, then it will turn it off when the engine doesn't start. That couple of seconds will be enough for our test - by the way, fuel pressure testers are available as loaners from most major auto parts stores.

Please let me know what you find and we'll continue tomorrow.

Best Regards.
