2005 dodge diesel 5.9 truck wont start unless given a small spray of ether....when it starts, it runs fine, but as soon as its turned off...it wont start a cpl seconds later.....please HELP!!! Thanks

 

Hope ya dont have your grid heater hooked up........

Ether + grid heater = BOOM!

 

im sure its hooked up but ive only gave it a shot of ether to get home....after that...i havent sprayed it with ether....but im still not sure why it wont start.....

 

Un[plug your FCA see if it starts! Shut off if it does! Fuel filter lift pump CP3 even loose cross over tubes will do it! Bad injectors not so much.

 

thanks dangerous1965, ill take a look. this is my first diesel and itll take time for me to figure out the mechanics and kinks of it....i could use all the help i could get....Thanks all!!

 

if i unplug the FCA, what am i suppose to look for or listen for....if the FCA is unplugged, how will i know if the FCA is bad?

i was also told the problem might be the Pressure releif valve is bad....? please help....

 

Unplugging the FCA will give the rail full pressure. If it starts then you know the PRV may be bad or your return flow from the injectors is too much! It will rattle like a beast so plug it back in and it should return to normal in less than 30 seconds!

 

GRRRRR!!! FCA has been changed.....Fuel Injection Pump has been changed....throwing code P0088 (fuel rail pressure too high) and P1652 (Comm Bus)....Im stumped....the engine is turning but not starting....somebody please help...
