1991 eagle talon big project

[gsxvince]

the ecu and harness were fine in the other car so its prolly fuel pump or something shitty

[gsxvince]

well i brought it to map and they have fixed the oil leak the fuel injector problem and did a few other tests and it still isnt working properly.
so its still at map and they will be working on it untill its running how it should be.
then it will be my dd
ill start by cleaning up the engine bay and doing some miner body repairs

[gsxvince]

so i have an important question i need answered is the cas the same from 1990 to 1994???

I would start over with this thread....

So you had a NT shell, swapped the ENTIRE chassis harness from the running shit turbo car into the NT shell? What years where these cars? Did you swap all the intercooler, fuel pump, FPR, injector resistor pack, MPI relay? You need to match the year ECU with the proper CAS, the pre 93 ECU will need a green top CAS, or the 90 CAS with the 4 wire pig tail, but a black top 93-94 CAS will not work with the older ECU, I am not sure if a 93-94 ECU will work with a older CAS.

Also check your grounds, get on All DATA, or go to the library where they have wiring schematics, or something to double check every connection.

If the 2 chassis were different years and you just swapped the engine bay harness I would guess you are having electrical issues up the wazoo.

Good luck fixing it, but with out more info I am with Halon, swap it all back to the turbo chassis and see if it runs better.

i never had a turbo chassie and im almost 100% sure its the cas issue so i think you just solved my problem
i have a new wire harness coming in and ill swap cas or buy a new one if mine doesnt work

because i just got it back from map and they said everything is fine so they have no idea why it doesnt work they couldnt figure it out

[goodhart]

You didn't need to swap the entire harness in the first place. All you need to add to the N/A harness is the resistor pack, and knock sensor. Seems simple enough, the knock sensor is one ground and one wire to the ECU

well i did what modern told me to do

[gsxvince]

ok so i took out my maf and put in a gm maf and the maf translator thats set to all zero
the cal is running the best it has now id say almost perfect.
but it will die if i dont keep giving it gas
anyone have any ideas

[blackrosenova400]

Ever check for codes?

[gsxvince]

no check engine light comes on but no i didn't.
idk for sure if map did or not but they said everything checked out ok!

[blackrosenova400]

So as soon as you give it throttle it wants to die?

[gsxvince]

no if i dont give the car gas it doesnt run.

[blackrosenova400]

Sounds like you maybe have pins 6 and 14 switched at the ecu and would cause this issue.

Look at pins 6 and 14

[gsxvince]

do you know a good amount about wiring in a 1990 1g?

[gsxvince]

so it wont go past 30 mph and runs shitty
i really need some help with wiring and a few other things if someone can come help ill pay them for there time

[gsxvince]

so i might need a new fwd tranny too
looks like mine is leaking for no reason now..

[Alpha D]

See plenty help jst gotta ask right Switch that gas! Put in the pump and fpr if you haven't ...and don't ovrr look another boost leak down test...that custom set up you got is just begging to leak. Make sure that maf is adjusted right as well, I guess they can be tricky when it comes to driveabiliy verses idle. Once it runs decent remember the aecu must also relearn all its fuel trimms so gentle atleast that helpd on my car! Have Fun no rage quitting lol

[Alpha D]

I think I know someone with a tranny 2

[gsxvince]

well i cant do the wiring myself i tried
im trying to trade an awd tranny plus mine for a good fwd
if possible
i dont have a pmup yet either

[gsxvince]

so i just picked up a few things from a junk yard.
for 150 i got an ecu with dsm link with cable,
2g maf and pipe,
650cc fic injectors,
nicer gauge cluster,
new headlight cover,
and a ss clutch line

i think the ecu needs to be fixed though
