I'm in need of a little more specifics
you stated that " Not likely. Just plugging and unplugging sensors will do that"
so does that mean by having the sensors removed without the battery being disconnected, this could lead to, cause the fried PCM/ECM. Here's the list of sensors removed/work performed with the battery connected. TPS Throttle Position Sensor removed, also removed the (IAC) idle control valve along with the throttle body unit being removed and cleaned. Along with the (MAP)sensor and the (MAF). ALL these where removed, new parts installed in an attempt to remedy the situation, the situation being the truck was running like crap, lack of power, hesitation, popping, long story short. The mechanic at a last ditch attempt to find the problem did a compression test, the results where 65psi in 4 cylinders, the rest of the cylinders where at 90psi. So the problem was found. No compression, the motor was rebuilt, reinstalled. The day came to pick up the truck, went down to the shop and mechanic stated he placed the wrong piston rings in the truck an that it would have to be rebuilt again! So now where on the second rebuild, the 2nd motor reinstalled but now the Mechanic says the PCM/ECM is fried. So my question is could this be the fault of the mechanic an error on his part? Or should I have to foot the bill for the new PCM/ECM.I'm down here in southern Mexico, Oaxaca. And ther's no auto zone or napa auto parts here, so I've gotta ship parts to the u.S. The question being did the mechanic working on my truck inadvertently fry the PCM/ECM. Is it standard to replace when replacing the motor?
Thanks again
eric
