Hello all,
first time posting but not reading 😉

So I have an issue that is killing me and making my wife angry with my lack of repair 🤣

When driving i lose all power to the engine but not the cab. It's like someone turns off the key for a split second then back on but without interrupting the radio/HVAC or lights. When this first started I got a code for crank sensor voltage so I replaced the crank sensor but now the problem seems to be getting worse. While driving to work it stalled at a stoplight, when fired back up I could not accelerate past 10mph. If I tried to accelerate to hard or go past 10mph it would start bucking horribly.

I ran the codes on it and have a p1336 for the crankshaft sensor not being synched and p0430, nothing else. I do not think either of these would cause stalling and bucking during acceleration but I could be wrong. I cant afford to take it to a shop right now so any help would be appreciated

 

You may not have a choice to take it to someone. When a crank sensor is replaced it needs to have a relearn procedure done via a scan tool.

 

Something you might want to look into,
Diagnostic codes do NOT always mean a/the sensor is malfunctioning!
A good part of the time it is bad connections and it may take someone with the info, tools and some experience to pin down the problem.
Codes generally only provide some guidance as to which system is involved.
A lot of the systems operate on a very low voltage and the slightest resistance due to a poor connection can render the system faulty or inoperative.
