Yes it is plugged in, it will run all day if it starts, but 3 out of 10 times it wont start, only crank. If I keep trying it will start after 5 or so minutes.

Have you checked the timing?

Done a compression test lately?

Timing - yes after changing tfi module
compression I feel is irrelavent seeing how randomly it wont start, when it will fire up, it is very quick

does it start when its cold and not start when its warm or after it has been running? if so check the O2 sensor connection and wiring

makes no difference hot or cold , purely random. I think that no matter how bad an 02 connection is or even unplugged, would never cause it to not start.
