yes till we let off the ignition then it wont continue to run still have fuel at this point but it acts like you just shut off the key again not real schooled in fords trying to get this up and running for him with no luck i know the green wire out of the coil stays hot as soon as you key it up not sure if it is suppose to or not with tester on it no juice at all pull away the tester and it is hot again solid thanks for your reply

Ignition switch...............you can test it by runnin a jumper wire from the hot side of the solenoid to the coil, if it runs fine, then you will have to pull that wire off to kill it, but you will know the problem, if not, then not sure..............

So you've put constant power to the coil & it still dies?

try the "idle air control valve". My wifes went out a few years ago and I could start her explorer and keep it running with my foot on the gas but as soon as I took it off the engine died, just like you are describing.

Agreed. Had the same problem you are describing with my '97 4-cyl Ranger. Replaced the Idle Air Control valve and started right up with no subsequent problems.
