i just put the tpi back in the car. all new sensors ewverythings bolted up right and it runs and will take wot but theres a vac leak somewhere and it pops out the tail pipe. digi scanner throws codes 51, 25, 32, 33, 34, 35, 36, 41, 43, 46 and when i manually jump the connecter the SES light blinks code 12 nonstop even after minutes. pulled computer and prom everything seemed snug.

I don't know about the scanner but I solved all of my codes using the ECM. When you jump the A and B the security light will blink code 12 3x then show any other codes (bad codes) after all of the bad codes it will blink code 12 to tell you are done. 12 is the beginning and end indicator it is not a code.
Find that leak and mabey adust the timing because vacume problems(forgot to hook up my brake booster) mainly gave me popping in the air cleaner nothing was going on in the tailpipe. My 2 cents
good luck

it only reads code 12 itll flash code 12 for minutes straight. no popping out air cleaner just the tail piper. with the est conencted my car runs at about 10btdc but when i disconnect the est(red/pink) wire it turns off

Yes mine will show 12 untill I pull the paper clip out. But you have gas igniting into the tailpipe that means the exhaust valve is closing late. Otherwise it is pretty much impossible for that to happen. Try(I am not a timing guru) adusting the timing by ear even if you get it right then you may have to redo the minimum idle adjust. At least you won't have backfires which can do things to the converter ect. I like the 85's
Good luck

i cant adjust timing as it wont run with the est disconnected and i set the car at tdc with rotor at #1 thanks man i need alot of it

Don't pull the power wire/s off the coil!
Just adjust the distributor by ear. Using a timing light add 2-3 deg and road test it.

got her done any ideas on the only getting code 12/test code from the manual read. when i reset the ecu then turn the key to ON i still get a check engine light?

'when the key is on the light illuminates that is how you know it is working (not burned out)after starting the engine it should go off.
