I have replaced the fuel filter approx. 6K miles ago but did not do the fuel accum.

It is a starting issue otherwise it runs fine. I have not been able to confirm that the M104 motor has a temp. sensor for the injection system.

I have replaced the fuel check valves to no avail. At least it did not affect the issue which is starting. It was starting when cold but now it seems cold or hot it has intermittent problems starting, stranding me at times. Then when I go back later it starts.

Got up this AM and no starting at all.
