It either won't start at all or cranks for like 10 seconds b4 firing, I'm now having to plug in the block heater when it's +5 degrees celcius (42 degrees Fahrenheit) or colder. I've replaced the fuel injector pump and the transfer pump, had a few computer updates and still the same problem. Anyone had similar problems?

 

is the grid heater working? fuel filter clogged? check the basics

 

new fuel filter and had the grid heater checked and they say it's working and I can hear it come on and turn off

 

Maybe a bad injector. If one is leaking it will bleed the presure in the rail and cause a hard start/no start condition. Run a search on here there are several threads that cover this issue.

Good luck and hope you get your truck fixed.

 

have a good shop or dealer check the injectors for return rate, if they can or have them shut the injectors down one at a time.

 

Your injectors are no good one or some. My 03 was the same.How many miles do you have ? I pluged mine in for 40000 mile then they would not start at all even warm. Changed them and it starts right up any weather.

 

Thanks guys, but will having it plugged in make a difference if the injecotrs are pooched? What's the cost of replacing injectors?

 

What was the cost of replacing and did you replace them all?

 

their about 400 ea usaully if one goes others will follow

 

Let me guess...there's 8? Was yours difficult to start in rainy weather too? I've got 190000km and the problem started back around 170K.

 

There are 6.
