Hey,

I have a 90 SHO that has been having problems lately. First, I had to replace the alternator and battery because after sitting for a number of hours the car wouldnt start... no juice whatsoever. Got that fixed. Then, coming home from Carlisle last weekend the fuel pump failed... so I got that replaced and the car ran fine this week.... until today.

I get in the car... all the lights in the doors come one, so i dont think my new problem is electrical... anyway... i put the key in and try to turn the car over... the key goes, but no result... i hear noise (sounds sort of like a farting noise actually) and the tach jumps from zero to 500. all the electrical systems come on (radio, dash lights) but the tach does not move above 500rmps. i notice that when i step off the brake, some of the dash lights fade in and out like when the car is about to stall... what could this be? again, upon trying to start it up the tach goes from zero to 500 where it stays until i take my foot off the brake.. then it goes to about 400... release my foot, back to 500... it doesnt really sound like the engine is running at all.
if you can, please help. i am getting very fed up with my car and frankly dont trust a shop to tell me what is wrong with it. thanks.

You might try replacing the starter relay. Its rather cheap. It is located on the driver's side on the fender wall. Its about 2-3" in diameter and is black. It has terminals on it. Its more or less a junction power distribution box for the vehicle. These are known to die after awhile. Its right next to the air filter box in front of the strut housing.

I second twrsho. It took me a long time to figure out that my funky electrical behavior was due to a loose negative clamp. Since you just replaced the battey, its a smoking gun.

update... the shop called... apparently the mercury switch under the hood was in upside down causing the hood light to be engaged when the hood was closed... this caused the power drain. hope theyre right. thanks for the help all.
