Hi Guys, I know ether is bad I parked it!!
Im new to this site I have been reading alot of threads on hard start issues! Im in the process or getting a fass or air dog and im gonna run a fuel pressure gauge?? I started looking at small things on the two solenoid's looking things beside the passenger side battery I have a ton of corrosion im cleaning all of that. But I know two of the wires on it run back out to the heater element in the intake elbow? could this make it not start?

Another issue is under the plastic head cover there is some sort of breather tube it was blown off just laying there? the metal head cover is nasty. could this also make it not start?

Thanks for any help! Ryan

more then likely your injectors have gone bad allowing fuel to return to the tank and not build up enough rail pressure to open the nozzles

Should I try the new lift pump first? then injectors?

Thanks!

can be a LP if it is just starting to fail
run a LP volume test, 1/2 qt. in 10 seconds minimum.
a LP gets minimum voltage and current under cold crank conditions = minimum output.

run a rail pressure test.
cold crank, 3k psi minimum, 5k psi for quick reliable cold wx starts.
warm op temp cruise at 2000 rpm on the road.

a HPCR with fuel system meeting specs doesn't need the grid heater for quick starts until below 0d F.

you can checl your lp which you should but your gonna find its a rail pressure issue since i have been thru this stuf on my 03 about 4 times before i got rid of it and once in the 06. do a return flow test off the injectors first to save time
