My 03 has 170,000 miles on it and recently has got harder to start and some mornings takes 5 or 6 cranki9ng cycles.I have even taken the fuel filter out and put it back in and sometimes it will start right up after that.I installed a new Raptor fuel pump 3 months ago and is still working fine.It lately takes 3-5 seconds before it fires up and then runs fine the rest of the day,but it doesn't like the mornings(exspecially if it is cooled off)everything I have found on here leads to injectors but i am wondering if there is any other things to check.Batteries seem a little week after a couple cycles and i assume they are stock since it was 6 months old when i got it and I haven't changed them.

I would say that you have an injector issue. Have you ever put injectors in before?

 

[intimidtr3]

No,I have necer done anything to the injectors.

 

[mdcody101]

odds are you have an injector issue if you want i can email you the info on how to test the return flow

So it doesnt like to start when its cold? As in cold outside temps? Is it blowing white smoke? Could be injectors.....what about the grid heater?

 

[mdcody101]

heater grid failures will set a check engine light. But to check them take a test light and see if you have power coming to the grid.

 

[intimidtr3]

No white smoke and what I mean is not ran for 8-10 hours.

MDCODY101 would you send me the steps to test the injectors please?

 

[intimidtr3]

Went to tow it home yesterday and it fired right up and ran perfect.What gives,I don't want to drive it if it is going to screw something up.

 

[intimidtr3]

I have noticed when i go to start it if the wait to start light cycles fast it will start if it cycles slow it will not.I thought i read something about a grid heater or something going bad and will cause a no start,can anyone help me with this?

 

[ssmoky01]

I have heard that people are taking em out. Sounds like a grid heater issue not injector issue due to the fact of abnormal cycling.

Could I get more info on it?
