Hi Douglas! Thank you for choosing ExpertHelp.com. I just want to know if your battery is still in good condition?
battery is good alternator puts out 13to14 volts steady
Thank you for your response. Try to remove the negative connector on your battery for five minutes and then put it back again. Make sure it is properly connected when you connect it again. Then start the vehicle and try to ro step on the throttle. Tell me what will be the result. I will be standing by.
i already tried that it does the same thing I have checked all the sensors and the pcm for water damage it seems ok I think that something is bad either in the alarm/ security system or of that ilk I have put a ford approved scanner on it and all the info frezzes just like you shut the key off
the engine runs good and if you dont go past 1/2 throttle it can go as high as 3000 rpm's but as soon as you get the accel at the point it dies and the battery light comes on and the alarm/security light flashes, if you let off the accel it wil come back and run
Have you tried using a OBD 2 scanner to check for error codes? You mentioned you check all the sensors, how about the TPS or the Throttle Position Sensor? Because if this is failing you will encounter this problem.
yes there are no codes or anything no cel nothing everything says it should be running like a swiss watch. the tps is new and goes all the way to 4.5 volts no problem the cam sensor makes no difference when disconnected the crank sensor was checked with a known good one
I see. Have you tried spraying the throttle body using the carb cleaner sprayer? If no, can you try it now. And after you spray it leave for 2 minutes and try to start it again.
I tried that already the power to the injectors and coil goes off like you shut the key off no spark/no fuel
I see. I will ask for a second opinion on this issue. I will opt out and a new expert will take over your issue. You will be notified via email when a new Expert contacts you for continued support for your issue.
