My first winter with this 93 2.3L and I am struggling to understand why it will not start when temps drop below 20F? Above 20F the car fires up from a cold start within one or two revolutions of the crankshaft, the warmer the outdoor temperature the quicker it starts. It will start immediately from a hot start condition. Below 20F the engine cranks harder and slower, almost starts, but not quite. Acts like when the timing is off on an adjustable ignition car, too advanced for winter. No codes.
Thinking of temperature related items I checked the ECT and IAT sensors and both are good. I tried starting fluid and no affect, no start below 20F. Through the process I have changed out and changed back, the DIS, Coils, Crank pickup sensor, none of these impacted cold start below 20F and all performed the same and well on warm weather starts above 20F.
Anyone else experience something like this?
Only modifications are 11:1 compression, mild hydraulic cam (pulls 19-20 inches of vacuum at idle), K&N filter in factory air box and about 8K miles since rebuild, all else is factory stock.
Thanks,
