Alright guys I got a 2003 Dodge sitting here in my shop I been stumped on the pass two days. I will only start on ether but will start right back upafter shut off but if it sits for over two hours you got to give it some juice. So I went thru the usually checks I got no pin hole leaks the air dog is providing more than enough pressure cause I seen some of those with intermittiet problems and all the injectors were replaced 3 months ago at the dealer is there a possbility that the could already be bad with a horrbile batch of fuel? But that would ruin more parts in the system. Also I got signal all the time from the crank sensor cam sensor fuel rail pressure sensor and within specs while running I got about 6000 from the sensor but wierd thing is I do not show any at cranking from my gauge so could it be the pump? I'm at a lose right now any help would be great

 

inlet grid heater works?

 

Yes Sir no problems with that and will not even start in a sixty five degree shop

 

any codes at all?

condition of fuel filter?

 

No codes at all nothing is showing up on the computer code wise and fuel filter is alright I would change it but I have seen alot worse

 

this is a fueling problem, change the filter anyway and see how it does

filters can look good yet still be plugged

 

Ok so the filter has been replaced and still the same thing will not start up unless you ether it

 

had one do that. Bad injectors. send em off and have em tested.
Whats rail pressure?
You are unhooking grids when trying to start on ether...i hope....

 

sounds like a low rail pressure issue. injector / tube issues.

 

Just saw your rail pressure. I would check the fca and overflow.
