Car wont start. replaced fuel pump (twice), fuel filter, fuel strainer, tested starter, replaced crank sensor, replaced computer. can put fuel directly into intake and will start.


Definitely not a knock sensor.

Just to clarify, you spray starting fluid in the intake and it will start and run for a short time and then stall?

My 1993 cutlas supreme stalls randomly while idling or driving , but restart right away


You will need to change the crank position sensor first and see if it corrects the problem. It is located behind the engine near the firewall. It's a bit tricky to get to it, you would need to rotate the engine forward then look under the exhaust manifold and under the cylinder closest to the drivers side. Use a 10 mm deep socket to loosen bolt. After replacement and it is still stalling then you will need to replace the ECM (vehicle computer). If it turns out to be the computer, go to your local junkyard to get an inexpensive replacement Click on the link below to view the CPS, it is around $22

Stalling issue


If your car has high miles and you haven't changed the coil packs, that may be your problem. Bad coil paks will cause hard starting, rough idle and stalling.
