When installing the interrupter magnet onto the sprocket through the camshaft sensor hole, which way does the magnet go in? Does the brim go in first, or does the magnet go in first?
I have changed the Crank Sensor, Camshaft Sensor, PCV Valve, MAF sensor, fuel filter, Oil Sensor Switch, Fuel Pressure Regulator, Spark Plugs, Spark Plug Wires and the car still won't start. I'm not sure what else could be wrong.
My radio worked, then all of a sudden after inserting a cassette, and removing it, the radio or cassette player doesn't work. I can hear a noise thru the speakers when I turn the power on, but nothing else. The clock does work properly.
car will not idle
Why does the engine stall occassionally when the air cond is on? No codes. Have replaced crank sensor, throttle position sensor and ecm since these parts may not give out codes when stalling. It stalls when in drive but will start back up immediately. Problem happens only when the air cond is on but cannot duplicate when the car is in the repair shop. No starting problems. Fuel pressure is fine.
my front brakes wont work and everything is hooked up right.
I have a 1990 Buick LeSabre. When I start the car I hear a rattling lick a stone is in the engine or transmission. When I drive it it is stuck in first gear. Reverse works.
