hay guys just wonderin if any one has ever had this happen to them, i kinda woried

I have a 99 SD 7.3 with a superchips 1705 set on tow with 232000miles on it and yesterday morning when i went to start it it wouldent start smoothly i had to hold the gas down and keep the key on for about 10s while it was turning over before it would catch and run fine and after it was warm i shut it off and it fired up fine it was about 10 deg F out side, normanly it starts at minus 30F with out a problem.

I put my stock program back into it when i got home last night and this morning when i went to start it it fired up with out a problem, Im wondering if i got CPS problem or if my chip is screwed.
thanks for any info

 

More than likely the glow plug relay (GPR) is dying on you.

 

any codes? I had the same tuner and had no trouble.... I will have to agree with pocket try the gpr. You can get a gpr at napa for about 10 bucks. Try that and let us know.

 

Thanks for the suggestion i will pick one up tomorow and try it
