Water intrusion into a connector (X309) located under the cab, beneath the driver's seat, can cause a rough idle, erratic speedometer operation, ABS Light and Check Engine Light illumination, and automatic transmission shifting problems. If needed, connector repair parts are available from Mazda dealers, and possibly some Ford dealers.

1994 Mazda B4000 Problems
If the engine cranks but does not start, it may be caused by a tripped inertia switch. Switch the key to "ON" and the fuel pump should be heard running for a second or two. Listen at the gas filler if necessary. The inertia switch is located on the firewall and can be tripped when the parking brake is set too hard and then released. The inertia switch should be reset, and will click when it is reset.
The engine may fail to start due to an electrically shorted sensor. Some of the sensors may internally short and not blow any fuses. A technician may find no spark and no operation of the fuel injectors in the diagnosis. One way a technician may isolate the defective sensor is by disconnecting sensors one by one to see if the engine starts.
A dirty, or contaminated mass airflow sensor (MAF) can cause the engine to run poorly. The Check Engine Light may or may not illuminate. MAF sensor related fault codes P0102 and/or P0103 may be stored. In some cases, carefully cleaning the sensor element will fix the problem. If not, replacement of the sensor may be required.

RepairPal Expert Overview:
Ford has recalled Firestone Wilderness AT and Radial ATX tires installed on multiple lines of Ford trucks from 1991 to 2000. On some tires, under extreme conditions, the tread could separate, which can cause immediate tire failure. This may lead to a loss of vehicle control, injury, and death. Dealers replaced the affected tires.

I love me truck. However recently it stallesd, I had to wait 5-10 min for it to restart. Thought it was the cadiledic converter as it ran rough and the exhaust was red. Now it doesn't start when it is hot. Have replaced the oxygen sensors,the ECT sensor, ignition moduale, TPS, and the feul filter. After the feul filter replacement the truck randomly chugs whe going down the road. Still won't start when hot. I am lost but still love my truck
