as in NO START what EXACTLY do you mean?

Customer: replied 1 year ago.
It cranks but does not catch. As if it's not getting any gas.
Expert:  bill replied 1 year ago.

ok so a battery or jump will NOT be the problem here since the engine is cranking i assume at NORMAL cranking speed?

what tools do you have and what is your skill level?

you will need a code reader or better a scan tool a fuel pressure gauge and the necessary adapters to check fuel pressure and the tools to remove the fuel line

I see! Thanks. I'll give it a try.

give what a try? you could have quite a few things happening here from a dead fuel pump to rodent damage to a dead crank sensor, or any number of things, a fast and dirty test on th efuel pump is spray some carb cleaner down the throttle body while having a helper crank the engine if it starts OR tries to start you have no fuel pressure, that could be a dead pump or wiring to the pump, sitting vehicles are often homes to rodents that LOVE to chew wires
