Hi, I've had a gmc savanna cargo truck since 2002. In 2005 I found a guy who replaced the fuel pump for me as the engine had started cutting out randomly and often. Apparently there is some kind of lens that detects dirt( for smog purpose)and when it goes bad the entire pump needs replacing. We also had the fuel tank cleaned out. Been running fine till now. Same problem. Can't find the guy again and gmc dealer will probably want serious cash to replace the pump. Is there a way of bypassing this lens yet( if it is a lens)does anyone no what I'm talking about, or am I full of ****!!

 

im guessin this is on a dmax? have u ran the codes on it yet?

 

Its a 6.5 according to his info....

 

Sounds like pmd to me i could be wrong but never herd of a lense in ip sure he didnt just change lp n or filter n charge u for ip to make money lot of people do that!

 

i like know what he talking about a lens can you take pic of it ? or less you are talking about the screen in the inlet fitting on injector pump you can just pull it out clean it with brake clean let dry good

Do you have any codes and where is your PMD mounted IP or front bumper

need to do some easy testing first check being 97 out 12v power right to LP see if it working
