New here and would appreciate any help.

I am working on a 97 caravan 3.3L 123,000. It had a cam code and would intermmitatly die but would resart, replaced cam and crank sensors and wont stay running or runs and dies. Thought mayby bad parts but tried another new cam and crank sensor and still wont run correctly. Have also tried new computer and tested wires from pcm to both sensors all ok. No codes but my not run long enough to set codes. Any ideas?

I am a chevy person but thought I could tackle this project, guess I was wrong.
