Hello, I'd be happy to help! First, do you have access to any diagnostic tools like a scanner or fuel pressure tester?

Customer: replied 5 months ago.
No
Expert:  Roger replied 5 months ago.

Ok, the only way to accurately diagnose a crank/no start concern is to use a scan tool. You could be looking at replacing a fuel pump, camshaft or crankshaft sensor, or you could even have an internal engine issue. If you don't have access to basic diagnostic equipment there's nothing I can do that will help you. Your best bet is to have it towed to a reputable shop. Good luck and have a good evening.

Hello and welcome to JustAnswer!

As mentioned above, it's going to take some testing to determine the cause of the no start condition. There are literally dozens of things that can prevent the engine from starting. You could be missing spark due to a cam or crank sensor, wiring issue, incorrect cam timing, you may be missing fuel pressure due to a failed pump or a loss of power or ground to the pump. The problem could be fuel contamination or an exhaust restriction.

Do you hear the fuel pump run when the ignition is turned on?
