Puzzling question

Cre & Green,

Thanks again for the replies.

Cre - all fuses are are good. Main EFI & Fuel Pump relays are making an audible click when keyed on. Can't find my Ohm/voltage meter atm. *grumbles about sons & grandsons and missing tools*

Green - Checked the spark on all 6 plugs earlier. Should have done a compression check while I had the plugs out, but assume it is fine(new gasket in 2008). I'll do that as a precaution tommorow when I have light & its not so cold ; ). New timing belt as well in 2008. I unscrewed the oil cap and watched the cam turn so belt is good as well.

I'm only hearing 1 click on the EFI relay so maybe it is not powering the injectors I'll check that tommorow as well. Maybe some kind of fuel cut problem. When I pulled the plugs they & the tops of the pistons were dry , no fuel smell. When I jumper the fuel pump it FLOWS, so no pump problems. Thought maybe the 51 code might be affecting the fuel circuit.

Again all help is appreciated, I have a very basic understanding of EFI, but definately no expert.
