I recently installed a GDP 392 with big line kit. Truck ran great for about a week. Now it has to turn over about 10 times to get it to start. Dies while driving (usually on acceleration after stopping), and blows out big puffs of white smoke. Have set all tuning back to stock and still doesn't help. Also surges under light throttle and sometimes at idle. Any suggestions would be great. This has been going on for about a month now and its driving me nuts.

 

Does your Glacier bypass the stock lift pump?

 

Yes it has its own dip tube and supply line.

 

And your codes are P???? What was the reason you put in a GDP 392? Did you have drivability issues then?

 

Check the oil level. If it's way above full, injectors are out.

 

Crawl under the truck and double check all the fuel connections. I put a glacier on the wifes truck when the stocker died. Love the pump but was not impressed with all the cheap fittings. A small air leak can cause white smoke, hesitation, or stalling. Usually rears its head as hard starting but I have seen them all. By the way check the fittings. Just because they look clean doesnt mean air is not getting in.

 

Put the the pump in for future upgrades. Checked for leaks a bunch of times even dropped the tank again and put die in the fuel, nothing. The only codes I have got have been high fuel rail pressure. But I haven't got any of them since it started stalling really bad. Haven't checked the oil either, might do that when I get back home.

 

Your oil level does not necessarilly have too increase when you lose an injector.....if the body cracks yes....butis not always the case....if you got a P0193 high RP code...chances are you have an injector sticking closed on you!!! Git'r replaced.

 

Think they could have gotten clogged when doing the fuel upgrades? I don't want to replace them unless it has to be done. If I do I'll get a bigger set but don't want to spend alot on new ones if thats not the problem.

 

What about the FCA?

 

FCA is brand new from dodge.
