I got my 94 pickup up and running with the 1990 crown 1uz swap. I keep getting a check engine light soon after driving the truck and the codes are a 83 and 85. In my book they are tcm communication failure codes. Are these codes normal and if so is there any way to stop them from popping up. Thanks

drove it around for about 2 hours tonight the truck is so light it doesn't mind shifting 1-3-4

i have the stock engine ecu and stock trans ect. I've decided im just gonna drive it manual shift for now and buy a suprastick in a month or so.

had the crank sensor wire grounded thru the shielding when i extended the harness. And i fixed the bogging issue today turns out the fuel was turning off once it tried to switch to high speed

one other thing. Will a harness and ecu from a 90 ls400 run the trans and motor. I can get ahold of these items easy and might be a simpler solution to getting the trans working properly

so i finally got my swap into my 94 2wd pickup nearly finished. Shes running but im trying to figure out how to get the trans all wired up. I was just reading on another post that it wont shift without the proper speed signals hooked up and these are ran into the abs computer and then converted...

i got it running yesterday purrs like a kitten at idle runs great with about half throttle anything over half throttle it hits about 3,500 to 4,000 rpms and dies then it throws a check engine light and pulls up an 83 and 85 which show in my book to be related to the traction control module. Any...

I know how to diagnose. And I know how to read and understand diagrams. There's definitely no spark coming out of the coils. I'm beggining to wonder if the rotor buttons and cap may be corroded and not making a good connection between the plugs and coil. I'm going to use a test lead and see if I...

i tried pulling codes check engine light just flashes quickly without any codes. what do u mean to start it on aerostrt

still having no luck. Tried a different crank sensor. Ignitors are grounded and have power. Coils have power. One weird thing i did notice is that the wire that connects the coil to the igniter and tell it to fire has power, is this normal? And i know this is my first post on her but i have a 87...

ignitors are grounded i already verified that. I already have the sensor out so i just take a volt meter on a table and run a metal object across the sensor and i should see movement?

I just got done wiring in a crown royal saloon 1uz into my 94 toyota pickup. I've double check my wiring 5 times now i have power and grounds at all locations necessary for spark. i have power at the igniters and coils. I believe my crank sensor may be bad. I check ohms at the sensor and it's...
