Engine Mechanical problem
1990 Ford Tempo 4 cyl Two Wheel Drive Automatic 79,000 miles
I was wondering if someone has some experience with “1990 Ford Tempo" it is “model L".
2.3 L, automatic tran. Vin # 1FABP35X1LK234531. Odometer reading is 127,000 km (78,000 miles). The problem is that it doesn’t start and the problem wasn’t gradual, but all of a sudden… It was working fine one minute and then not starting the next. It sounds like it will, but doesn’t kick over… It doesn’t seem to be firing in the cylinder.
The vehicle has now sat for 4 months and the problem is exactly the same (yes, no secret fix-it gremlins snuck into my garage and fixed the problem…hmmmm). I mention this as it eliminates the idea that it could be flooded. I have confirmed that there is spark going to the cylinders (spark plugs). It also seems that there may be gas present in the cylinders as I can smell it when I remove the spark plugs and they seem wet.
Are there some easy checks that I can do to confirm that it is not “fuel delivery" related?
I found two trouble codes from the “key on engine off" section of the codes and they were
21 – Coolant temperature sensor out of specified range and
Engine temperature coolant out of specified range.
24 - Air charge temperature low
If this sensor isn’t functioning properly, could that cause my engine not to start?
If this sensor is functioning properly, could that mean that the thermostat is not working and could that cause my engine not to start?
In the old days, the engine would have still started… but perhaps the (EEC) computer that controls the throttle mechanisms will not let the Air/fuel reach the cylinder.
I had another tempo (1990, but a manual tran.) That had the same codes come up 21, 24 only the car would turn over and run for a short period of time (3-6 minutes) and then die. The problem then was an ignition module. I don’t think it is this as I am getting spark at the cylinder, but could this also be what needs replacing?
Any advice will be helpful,
have the same problem?
