So I took the alternator out found out it was bad. Replaced it and now it still just cranks. So I replaced a cam sensor b and a crank sensor and my van still just cranks. Van was running good until it abruptly shut off while in motion. Does anyone have any section in something to test or try? Please let me know
Thanks, Matt

Hello,

Do you have fuel pressure at the fuel rail? Have a helper turn the ignition key to "run" while you listen at the fuel tank for the fuel pump to come on and prime the fuel system. Please get back to us with what you are able to find out.

Thanks,
