SOURCE: quits while driving replaced many suspected parts

try this, the next time it quits leave the key in on position and get a broom stick and go to the passenger side of the car. About straight in at the back of the door ,reach under with the broom stick and tap the plastic gas tank a few times, have someone try to start it or go start it yourself. Mine did this even after the garage checked it out and cleaned the tank. Come to find out dirt settles around the fuel pump and clogs it. They just blame the pump but in my case the pump was fine. I was told Alero used a very small fine mesh in the sock that goes in the fuel pump and they clog up. But most of the dirt was around the plastic guard around the fuel pump. See if this works and let us know. Good luck

SOURCE: Vehicle dies while driving down the road.

could it be the A/C pump kicking in. might be boging down the motor or electrical circuit, not letting the injectors get enough power. This could happen if the bearings are going bad in th A/C pump or there is a short in it. Just an idea. sounds like you have done the main components.

Have a 86 ninty eight will not fire replaced cam sensor and crank sensor


check the timing marks twice and make sure crank is on top dead center.

if all that checks out ok i would check power to the coil(s) and the coils them selves... Also is the fuel pump make any noise you should here it prime.other than that make sure the gap from the sensors r proper if they are too far away the sensor will not pick up a reading.

1990 olds 88


You may have a faulty crank sensor again. Next time it cuts off hot, spray or pour water on it and then try to see if it will crank. These cars had a cutting off problem with ecm #1228253 but most of them would start right back up. If it has that number on it replace it.with #16198264 or newer number. Get a delco and not an aftermarket ecm..

While driving, the engine dies.


I had the same thing happen on a 91 Olds 88. Replaced crank shaft position sensor, coil, and ignition module. That solved the problem. I think the culprit was the CSP Sensor, but changed all three so can't say for sure.
