car wont start

[Fake Thug]

Well I got a new ecu yesterday, well not realy new its from a junk yard, and the car is still the same. The only thing i can think of now is a bad ecu conector. By the way the check engine light is always on not just when im looking for codes, what does that mean?
Any way thanks alot guys youve all been a big help

Ok, I got confused. I thought you said u checked for codes and got nothing,meaning 0. So when you check for codes how many times does the cel flash, or does it just stay solid? If your cel is on,it should flash a code or codes when you jump the diagnostic connector.. How many long, how many short? Find that out and I will tell you what the ecu is seeing and then we can go from there.

My bad didnt mean to confuse you. Well mi check engine light is always on and never blinks. As soon as i turn the key to ACC the light comes on and stays solid and never goes off, and when i tried looking for codes the light didnt do anything it just stayed solid.

Okay.. CEL staying solid when you jump the connector means that the ecu sees nothing wrong. So you stuck a paper clip in the diagnostic connector and turned to acc right? Its stays solid?..okay


The TCU is throwing codes 1,2,3,7,8, & 14


1 is lock up control solenoid Its either disconnected or shorted.A
2 is lock up control solenoid B...Same as above
3 is a disconnected throttle angle sensor
7 is BLINK: Shiftcontrol solenoid valve A
8 is ^^^^^^^^^^^^^^^^^ valve B
14 is FAS wire off. PGM-FI unit

First, Check your throttle postioning sensor. Its on the throttle body. If its not connected all the way,reconnect it. Check for resistance with a multimeter, check the wiring, bare wire,short. If the sensor is bad, replace it.

Dont work? Move on


swap the tcu with used one or a friend and see what happens

That doesn't work

Reset your solenoids. TO
reset them ,remove the backup fuse under the hood and reinstall it or disconnect the positive battery cable then turn the ignition switch on and off then reconnect the cable.

That dont work


Check you shift linkages. If they are out of adjustment your car wont start,
Check your lock upcontrol solenoids or replace them with used from junkyard
Check your tcu and transwiringfor obvious shorts/bare wire,bad connectors

Thanks for all that info mutch apreciated.
Whats a FAS wire?
By the way, I never noticed before, but when you put the key in the ignition and tun it to acc (not while cheking for codes, but before you start the car)should the check engine light turn on for a few seconnds then turn off or should it stay on until you start the car, because mine is always on and im not shure if thats normal.

Not normal. It should go off after about 5 seconds without starting your car.
