Hi all back again for my roommate, he was going to get a new battery for his truck and use his old one for the boat. But upon further thinking on it bought the proper marine battery for his boat instead. However lately among the crank issue where his truck will only click one time and nothing else trying to start it.

Today he went to get on the freeway for work, and he floored the gas pettle according to him pedal to the metal to build speed for merging. The truck start bogging out and back firing pulling 3 of 8 plugs I noticed he need a tune up again. So I replaced all his plugs double plat all 8 had no issue coming out or going in. He went to test drive the truck after this and it had the same issue only this time it fully died when he went to release pressure off the acceleration. When he went to turn the truck back over he put it in neutral and it cranked 2 times and didn't want to start the 3 time it fired up with some hesitation and still had a problem building speed and rpm flooring it however driving like in town conditions it has no issue...
Note this is a replaced engine at 50k miles from dealer, since purchase the truck has been driven about 75k to 100k miles. And has been shown for most its life in roommates care a lot of love. He has replaced a leaking rad, replace a water pump for the most part has been on top of his oil changes. Brakes he trys to stay on top of seeing as he drive a min of 300miles a day. The truck has a exhaust problem and it isnt minor however as much as we would love fix that no money at all, $2000 income $1500 living expenses two kids no money.
Exhaust issue, the cats have a few small holes and honestly small, one of the two tail pipes fell off due to rust, and I'm not possitive but from the sounds and what I seen it seems like just recently in the passed 3 days the exhaust manifold gasket may have blown out

4.7l 4x4
p0353
p0351

 

Update got the truck running fine, as the engine runs amazing and idles great. However the issue we are still facing is it not wanting to shift. We are getting it to 30 in first at 5000rpms before "we have to power shift it basically "" release the accelerator for a split second and stomp on it to make it shift"". If he drives it in town there's no problems with shifting but the moment he goes to getting to merging speeds from a stop or already rolling he has to force shift
The issue we had with the bogging and codes was a ground along the fire wall fell of in a short since just needed a new nut to hold it up

 

P0351 and P0353 are bad coil codes. Two bad coils will cause the problems mentioned. Exhaust problems will also cause the problems mentioned by not feeding the O2 sensors the correct values. You can unplug the O2 sensors in front of the cats, the truck will run but rather than running the correct fuel/air mix it'll set a code and run off a table. This will cause it to use more fuel and may reduce power output a little.

Has your roommate considered selling the boat to fix the truck?

 

He has concidered selling the boat to fix his truck, however he has left the decision of getting rid of the boat or not to his kids. He is a single father and this the main thing they do to spend time as a family is go fishing on it having picnics on the water and in general having fun with it. His son and him even do all the maintenance for it together. So he hasn't gotten rid of it yet, the truck had shown no signs of issues till two months ago when the no start click issue began. However now that we fixed the ground wire issue we hope that fixed all the problems because there's now no codes being tossed at all and the truck runs and idles fine now the only issue we are having is the shifting now and that's only getting to merging speeds and physically power to the truck. Just driving no issues in town shifts great. Freeway going around slow cars or getting to merging speeds just putting your foot to the accelerator in general and "giving it gas" it gets mad and makes you power shift

 

After unplugging the o2 sensors, replacing the spark plugs, replacing the pcv valve, and doing an other oil change at only 2k miles and fixing a dangling wire. The truck seems to be running 3000x's better then when he bought it

 

Replace your pre-cat O2 sensor(s?) then. NTK, or Denso brand only please. These trucks don't like Bosch.

 

Thank you for that bit of info, that explains a lot this truck has probably 87% Bosch sensors, bosch plugs right now, it has a lot Bosch in her

 

So not sure exactly what happen but the belt on the truck snapped pully was destroyed and truck killed it'self on the freeway ever since replacing all pulleys and putting on a new belt the truck has had zero start issues no click problem blinker is to still be addressed the relay is on order at my part store, gas milage right now is avg 10.7mpg without the o2 sensors which is almost a gal more then with them so that and the exhaust is going to be addressed next week
