There is no reaction when turning the key to start the car


Turn key to On.
Turn on headlights manually... Do they come on?
Are there any lights on the dash?
If yes to these, battery is possibly not the sole problem.
Check for good, tight and clean connections at battery terminal posts!
If yes to above, continue on & get a helper... Turn key past on, to Start position.
Do you hear a click sound at time key is turned to Start?
If yes, then ignition switch is not problem, starter relay is getting power, and is now sending power to starter, but starter is not working.
Pic any No's... Then look there.
Good luck.

97 ford f-150 PCM power fuse keeps blowing,


that could be a tricky situation because you don't know if it's the pcm itself or a circuit that it controls. first you must know whether or not it is a short in the power or ground supplies to the pcm, then if that is all ok, you have to disconnect all sensors, injectors, etc, everything that it controls and see if it blows a fuse. if it doesn't, then you have to hook them back up one by one and see which one will blow the fuse.

Blowes the pcm fuse when key turn on


Hi, if you have the 4-cylinder, only the PCM and the ignition is on this fuse. If you have the V-6, the camshaft and crankshaft sensors are also on it. What I recommend is to disconnect everything on the fuse except the PCM, and then turn the key on. If the fuse blows, you know your PCM is shorted. If it doesn't blow, reconnect the ignition module and turn the key on again. If the fuse blows, you know the ignition is bad. If not, plug in the sensors one at a time to see which one is shorted. The location of the sensors are shown below, but there are 2 possible locations for the crankshaft sensor. The ignition module is under the coil pack. Please let me know if you have any questions, and thanks for using FixYa.

Veh wont start


by looking at the wiring diagram for your truck. the pcm1 fuse only feeds the pcm so most likely it is a grounded wire between the fuse block and pcm. follow the wire harness closely between the two and see if its grounded somewhere. also try disconnecting the pcm and see if the fuse still blows. that would isolate the problem to the wiring. it is highly unlikely that the pcm would cause the problem.
