Hard to start

Turning the ignition key's on and off is leading me to a dirty fuel filter or a bad fuel pump sending unit. Pumping the accelerator peddle does nothing but keep your figure since the engine is fuel injected. Check your fuel pressure at the shredder valve, you should have 60PSI to 65PSI when the key's are at the run position and should drop around 5PSI when the engine is running. There is also a valve at the fuel pump to energize the fuel line and when that goes bad you lose you prim fuel pressure to start the engine. Good luck and keep me posted, be glad to help.
