Car cranks but won't start after fuel pump replacement

[tmontague]

How did you determine that your fuel pump was originally faulty? The reason I ask is that the Yaris fuel pump is not known to commonly go. If this is the case then the original problem wasn't addressed hence the lack of start. What I find weird is that the car has never started since it originally cut out when you were driving. Seems that there may be another issue that happened and that still isn't fixed. Although what that issue is, is not very clear at this point.

As for timing, the chain can't really ever move by itself unless the timing cover was removed and tampered with.
