1993-9000-CSE Turbo/4 cyl/ TCS
Engine cuts out unexpectedly at any speed. Will restart right away.
On a couple of occasions I noticed the rpm meter bounce down and back up.
The starter is now wired directly to the ignition because was having problems restarting and could not isolate the problem. Engine now restarts all the time right after it cuts out.
Have replaced crank position sensor, ignition switch, throttle body, tried new DIC, cleaned earth grounds in engine compartment and one under dash on drive's side. Also cleaned the DIC connector and the plug that goes into the firewall.
Previously to throttle body replacement the car had a very heavy pedal with poor acceleration and occasionally the TCS would go into limp mode.
One night the car stopped and was not able to restart. Starter would engage but engine would not. When the DIC and ignition switch where replaced the car restarted but would continue to cut out.
Currently the car has the old DIC back on and a throttle body from a 96-9000. The throttle body has improved the performance of the car and the limp mode does not come on anymore but the engine continues to cut out suddenly. Have not been able to discern any pattern.
Help :)
Thank you,

PS- did ask my mechanic about fuel pump or fuel delivery but he didn't seem to feel that was an issue. Is there an easy way to check the fuel pump? Wondering if there is resistance building up in the electrical system that eventually shuts off the fuel pump? Because after cleaning the grounds I now have the open-hatch light on and the central locking not working. Fuse blows immediately when trying to install.
