Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.In order for the engine to start and run you need a properly charged battery, good spark to the spark plugs, injector pulse and proper fuel pressure ( 50 to 60 PSI). If you can check each one of these thing for me and post back with which one you are lacking we can work from there to determine the cause. Post back when you can.
I would stall check your fuel pressure, the problem could very well be a failing fuel pump, its pretty common for these pumps to overheat in hot weather and work again after cooling off.
