How to get codes without code finder?

Q:1.My local NAPA said there is a way to get a code from the car, with the blinking engine light, without a code finder...he said he doesn't remember how,but that you do something with your key and the engine light will blink...i've always though you need the OBD code reader for that...is he right?...if so, anyone know how?...thanks....
A:what sort of monte do you have and what year .As fgar as I know there is no way to do that with the key and engine light you need a obd to check engine codes .You can go to cap or advance auto and they will put the obd reader on your car . The guy at napa does not know what he is talking about just by him say"he doesn't remember how" is a dead giveaway he does not know. good luck
2.The blinking engine light for retrieving codes was used on GM vehicles with the OBD I through '95. But, some vehicles do not comply and require an auto scanner.
Q;i put in the jumper wire, turned the ignition to on, but not starting the engine...the check engine light blinked once, then stayed on...not sure what that means according to the instructions...i'm lost again
A:Is it a single flash or a series of flashes? 1 long and 2 short flashes would be a '12' meaning no codes have been stored. It may also be that your particular vehicle requires a scanner to retreive the codes.
Q:it's one short flash, then it stays on....
A:If no codes are being displayed when you jump the A & B terminals then it's possible that your vehicle requires a scanner in order to retreive any trouble codes. You are jumping them prior to turning the ignition ON, correct?
Q;yep...i put a paperclip between A and B...then i turn the ignition...it goes on, and goes off, then comes back on and stays on...i'll have to check a couple local mechanics and see if they have a scanner that would work on this year...my normal mechanic, for my daily driver has already told me he won't work ont he car because it's too old...he did the same with my 84 Bronco and has never worked on it...so i have to find someone new i gues...thanks....
i installed a new MAP sensor...let it run for a while to get used to it...tried to drive and it's still giving the same problem...i have to floor it to get it moving...if i don't feather it and i just slam on it, it stalls out and pops under the hood...once i get up to speed it cruises fine...so pulled it back into the driveway and did a seafoam treatment...started it up after 5 minutes, it smaoked, then stopped, but still same problem...so i tried the paperclip to see if any codes came in and i'm getting this one...21 TPS voltage was above 2.5 volts for 8 seconds when the MAP sensor signal showed manifold vacuum to be 15 pounds or more
A;If you're still getting the code after replacing the TPS I would double check installation to insure it was done correctly and check the wiring for the TPS to make sure the circuit is functioning properly. It's also possible that there is carbon build up in the throttle bore that is causing the throttle plate to not operate smoothly and hang up.
