The vehicle first started not starting all the time. It has a new fuel pump, crank sensor, cam sensor, starter and spark plugs. Now, it is getting sparks but will not fire. Any advice would be appreciated. Thanks.

It sounds like it might have jumper time, can you do a compression test to see if the engine has any?

There is no compression. You were right! They are going to fix it next week. I don't think they are looking forward to it.
