Asked by Tana Aug 07, 2020 at 03:54 PM about the 1993 Toyota Corolla DX Wagon

Question type: Maintenance & Repair

I have a 93 Corolla 1.8 7A-FE. The CEL is on. I have tried the jump many
times, but the light does not blink. Does the car have to be warmed up first?

I have new
spark plugs and wires
fuel pump and filter
(different) pump relay
VSV
IAC

The mechanic cleaned the throttle body and removed (but have not yet
replaced) the catalytic converter.

The engine quits even with starting fluid sprayed into the throttle.

My car still doesn't want to run.

I've heard rumors that if the speedometer doesn't work on the 7th gen
Toyotas, then it could affect the idle. Is that true?

The odometer is about 150K.

PLEASE! What's left????????????

The issue with all the parts is a bad ground from the ECU. After shaking the harness coming through the firewall, the CEL came on and flashed the code for the IAT (because I had taken off the air filter). The key was on, but the engine wasn't running.
