[does the number on the outside of the ecu mean much?]

No clue, but i doubt the ECU is your problem.

 

Did you look up barsotti yet?

got his number but wanted to see if i could try a bit more before i called him.

[does the number on the outside of the ecu mean much?]

i got a ecu out of a junked 1800 turbo wagon, same place i got the motor.

 

same year as my rx and nothing appeared to be wrong with the wagon ( hence why i picked it for the engine pull), well i plug the ecu in and try to start the car and nothing changed except now i'm getting no spark at all..

 

the mechanic well the car is says that the ecu has to be EXACT or else it wont work...is he right ?

 

my ecu number was a 53, and the one i pulled is a 27..any ideas?

[new to subbies.....just did an engine swap]

what happened to the old engine?

 

how are the fusible links (by the battery)? pull them out, make sure the ends are all clean and none are broken. reinstall.

 

make sure the engine connectors are fully seated. it is very easy to plug them in but not have them fully seated where all pins are engaged. double check.

 

is the CEL giving any codes in the trunk (LED on the ECu will flash the code for you).

 

check the distributor plug connection. check the engine grounds. forget where they are on the EA82T exactly. front drivers side of engine on XT6, but EA82T could very well be different.

 

the FET is a small dime sized device under the coil. it needs to be grounded and in good condition for the car to start. it's attached to the coil bracket and has one wiring harness connection.

 

make sure the distributor and rotor are good. pull it off and look. i've had brand new ones self destruct internally (and still spark...but at the wrong time). you get no spark at the coil or plugs?

 

you didn't do any swapping of engine harness, distributor, body harness or ECU right? all that is identical? same year and model EA82T? all EA82T distributors do not interchange.

 

check this list and let us know what you find....sounds like alot but shouldn't take long at all.

 

 

THANKYOU gary,

i still took i to a mechanic near me and when he hooked it to his computer the only thing it spat out was a bad ecu...so yeah now i have to find a good ecu at pick and pull... unless junkie has an extra he's willing to part with....?

[new to subbies.....just did an engine swap]

well i'm loosing my frigging mind on this damn thing.....

 

i changed the coil out and the issue is still the same..

 

we are getting NO spark from the coil until i stopping trying to turn the engine over then i get one nice spark at the end..

 

and when it does start it quits immediately, i had it at 3,000rpm's and it was trying to die the whole time, then it just stopped and would not start again for a LLOOOONNNGGGGG time. i'm out of ideas and basically giving up...it goes to the mechanic in the morning, and if he cant fix it then there will be a 88 rx for sale soon! piece of @$##$ S#@t

[new to subbies.....just did an engine swap]

we have an 89 rx that we just did an engine swap with.. the new engine seems fine, but we are still haven issues. the check engine light is still on and it dies soon after it starts... if it starts at all.

 

i'm sure the starting problem is the ignition coil. we took the center plug off the distributor and held it to the body and tried starting the car, no spark until we stopped starting, then i fired off ONE healthy looking spark.

 

i know it's getting fuel and air, the timing is fine WHEN it starts.

 

any suggestions, would be greatly accepted
