Engine Performance problem
1990 Chevy Lumina 6 cyl Front Wheel Drive Automatic 112000 miles
1990 chevy lumina euro 3.1 engine. The car cranks, idles and excellerates perfect. No missing, no power loss and no surging or dieing at stop signs or red lights. So heres the problem, the car just shuts off like some one turns the key off. Theres no warning or symptoms before it shuts off, it just goes dead and will not crank or even try to crank for a couple of hours. The engine just spins over. If you let it sit for a few hours it cranks and runs great like nothings wrong and then dies after 15 or so mins. I've changed out the fuel pump and strainer and fuel filter. I've also changed out the Crank position sensor and pig tail to sensor and I've changed out the engine computer. I've checked grounds and all wiring going to injectors and sensors. I changed out the ignition control mod and all 3 coils. There are no codes thrown and the service engine light is never on.
have the same problem?
