05 TRD Sport won't start after rebuild

Since there are so many codes and they seem somewhat related, I'd check battery to engine block to frame grounds. Also it there is a common +12v going to the engine for the sensors / check all the wiring real good. Barring that - if the codes are consistent, Pick the easiest simple one code and meter it out .... (i.e low coolant)

 

As much as I love our Tacos, this is a great example of the beauty of an old school pre-74 vehicle. No computers, no guessing. Very simple to run down wiring issues.

 

X2 - I was originally thinking of checking spark - but today that voltage can kill.

I was trying to help to give them a starting point by tracing back from a known issues (i.e. low coolant, no power to fuel pump) but even that probably comes direct from an e module and it does not assist in telling if it's the module or an input. Years ago you could squirt some gas in the carb and jump 12v to the coil and see if it fires. On the plus side I have had very less problems with the later vehicles and they do last way longer years and mileage wise ... (but the cost of the vehicle as increased even more.)

 

Yes the advisor at the dealership suggested putting a new fuel pump relay in it and checking to make sure the fuel pump is getting power to it I guess process of elimination from now on

 

Good luck bro. Keep us posted on what they find though, I'm intrigued?

 

Any updates?

 

If the fuel pump relay isn't the issue, I'd be connecting a quality scan tool allowing live monitoring of all inputs and outputs before and during cranking, and there is a good chance it will lead you in the right direction. (injector duty cycle, verify fuel pump relay trigger, verify crank and cam sensor speeds, immobilizer status, etc...) I would have hoped the dealer would have done this, but did you take it in? Or just speak to a service adviser?

 

i didnt take it in just talked to an adviser went and got a new fuel pump relay and that was not it tomorrow i plan on callling the guy who does the work on all the company vehicles see if he has any thoughts or suggestions if not i guess ive gotta take it to the dealership :/

 

Well heres a long overdue update. After three months of having my truck back together got it to run today. Apparently some wiring issues between the fuse box under the hood and the one in the cab. The abs,break light and rear diff lock light on the dash are still illuminated. Along with the tail lights not getting brighter when you apply the brakes and my drivers side speaker and door ajar doesn't work, oh the joys of wireing but hey atleast its running!!!
