Code 43 also includes the coil, sure it's good? Might try the fuel filter, but I have yet to hear of one go bad. Maybe your the first

. Have you tried leaving the fuel pressure gauge on till it warms up and dies on you? Is it losing pressure then? If not, I'm leaning towards the coil. Any auto store around that have a DRB (diagnostic readout box) that you could get a read off of? Would be able to narrow it down with a diagnostic trouble code.
