Electrical Problems....looks like a common fault in DSM's

[90Tsiman]

I have a 90 Talon TSi FWD and im having a hard time figuring out whats wrong here. When you start the car it goes crazy...does not keep an idle, up and down revs, check engine light comes on and ive checked it already and there is no code. I sounds ruff when it runs unless I get it above 3000rpms then it runs smooth. I put the code scanner on it and there is no code but it said the voltage level was low goin into the computer (9.8 on run, and 8.5 on key on position with car off). What im thinkin is that there is a wire problem somewhere between the battery and the computer...but could I be wrong? Some ppl tell me that its the cam angle positioning sensor but Im not sure? Someone please help me? Any suggestions would be great! And what about a logger? Would that tell me anything....possibly a vaccum leak?

Thanks.......

Can't really help, but thought I'd mention that I've also observed that electrical appears to be a real weak point in 1g's

you could try the alternator or PCV valve, but i am also having a problem with my electrical in a 2g. my brake light and battery light are comin on.

Wanna hear some electrical problems?

My blinkers dont work
My hazards work half the time
I blow a fuse every week for my park lights
One of my fans work, unless you turn on the a/c then they both work
My dimmer doesnt work
My head lights pop up and down and stick half way while I'm just driving down the road
And I keep blowing relay's everytime I try to rewire the fuel pump

I am just waiting for it to catch fire from all those shorts one of these days

Well, THAT part is supposed to happen....

you prolly need a new alternator and you may wanna find out about your balance shafts

try a known good ecu.

iuno about the whole 2 fans on when a/c is on, mine 2nd turns on when my car gets to a certain temperature..not just cuz the a/c is on

 

[RoasT BeeF]

I am pretty sure they are both supposed to run. They both used to run whenever my car got to a certain temp. Then one day one of them jus stopped.

have you checked your ECU for leaky capaciters?, have you checked the battery and alternator? my 1g is having some major electrical issues and idle issues too. im going to have O-reilys check my alternator and battery and then ill be doing 3 different treatments for my idle surge. Not to mention getting my ecu rebuilt by the vfaq man.

I agree with Eric, I had similar problem. About a month later, the ECU went. Caps leak..

 

[ericismyname]

i got my battery and alternator replaced...all problems gone,..will be doing leaky caps soon to ensure my safety
