1996 plymouth voyager won't start replace cam sensor and crank sensor still won't start just turning over

Back to basics. You need spark, fuel, and compression (manifold vacuum). Before you replace any more parts, check to make sure that you have no stored codes. If your check engine light is on, retrieving the codes will point you in the right direction. If you have to, tow it down to your local Autozone. They will scan it for free! If the check engine light in not on, the problem is most likely the fuel system. So, locate the fuel pump relay under the hood next to the driver side front fender. Remove it and CAREFULLY remove the top by lifting the two clip tabs with a small screwdriver. reinsert the relay and crank the engine while observing the relay to verify that the relay pulls min. That is, that the contact moves. If it doesn't, check the fuse and the relay itself. (Swap the AC clutch relay, they're the same). If it does, try manually closing the relay with the key on while someone listens at the open fuel opening, (take the gas cap off first) If you don't hear the fuel pump running, it is probably the pump. Please note that I own a 97 voyager that is very hard to start, and I have often had to manually operate the fuel pump relay in order to prime the engine so that it will start. Hope this helps!
