hot start problems - but will bump

[zx_volcane]

as above on 1.9TD

any thoughts?

Won't start from when warm on the key, but will start a the mear hint of a bump.

Turns over fine, just doesn't fire. Runs fine otherwise.

Fuel filter was temp bypassed to rule out air leak from that area.

So has air free fuel, and assume has compression if will bump.

So thinking either ip problem when warm, something going out of tolerance and pressure dropping, or pump drawing in air when warm?

Or could a temp sensor be out?
