Hi, I'm Ron and I will be helping you today.
Stand by for a moment while I prepare your answer.

The problem can be a loss of spark or fuel. You can check for
spark at the plugs with a spark tester.
You can check fuel pressure with a gauge and both of these tools
should be available to you at your
local parts store for rent or purchase.
You need to check for any stored codes in the computer with a
code reader or a scan tool.
The code reader only gives the codes and definitions, where the
scan tool gives you all
the needed data to diagnose the codes.

Check compression with a gauge too, you may have lost the timing belt.

Thanks, Ron
