Sorry I Bought An A4

my 98 coupe hasn't started for weeks. it is giving me 2 codes p1518 and p0601. after doing searches of archived posts, it seemed that most people with p1518 had problems with thier TAC module. well, i tried a new one with no luck. i also tried mine in a friends car and it worked like a charm. what could be wrong? the battery is good, the engine seems to be getting fuel, but thier is definately NO SPARK. i also checked every fuse and they are all good.

any insight would be appreciated.

thanks
joe

First do you have a service manual if not p0601 is the first code to diag. do system ck ck fuses for injectors throttle control eng. 1 a/c do you have ck eng. light key on eng. off ? ck fuses with test light be sure they have power to them is your DIC displaying reduced eng. power start here let me know

i do not have the service manual. yes, i do have check engine light . i don't know how todo a system check. all fuses have been checked and all are good. the d.i.c is displaying '' reduced engine power, service traction control, service abs'' ect.

any of this ring a bell

:iagree:
This is saying that you have some type of memory problem with the PCM and the other one is saying that the PCM is not reporting to the TAC correctly.
Have you done any work recently, maybe one of the connectors at the PCM is loose

i haven't done any work. i was going to. on the day of the problem, i put the car up on jack stands and i was doing some stuff on the interior (cosmetic only) i had the door open for several hours and the battery ran down. i noticed a wierd noise coming from a relay or something and than the interior light went out. i changed the battery and than tried to start the car. wouldn't start and the codes came up.

the P0601 code is "PCM Memory". I would look at the PCM first...
