Question about 1999 Toyota Tacoma PreRunner
IVE REPLACED SWITH AND COMPUTER AND STILL THE CHECK ENGINE CODE P1780 APPEARS WHAT OTHER PROBLEMS COULD IT HAVE?
The codes need to reset with a diagnostic plug in device that may only be located at a dealers service center.

Check for fuel pressure when starting. Fuel pumps have a check valve in them that keep fuel in the rail at the injectors. If the check valve fails, the pump has to pump fuel all of the way up to the engine. Same thing with hot no-restarts. Fuel pump.

pull the E.F.I. fuse located under the hood on the drivers side, if there is more than 1 efi fuse pull them both along with the E.T.C.S. fuse (if there is one) for 1 minute or so. That should do it

An O2 sensor code is a tricky one. It could mean SEVERAL different things, and I know how bad it sucks to hear this, but your best bet is to take it in and have a diagnostic ran on it at either a dealer or a good mechanic shop with a computer they can hook up to it. I had an "O2" code come up a while back on another car I used to have, and literally spent weeks and hundreds of dollars trying to fix it, and never did. Finally out of desperation took it in, paid the $90, and they found the problem and fixed it in like 30 minutes. Something I would have never even thought of was causing it (can't remember off the top of my head). After that I stopped wating time and money on check engine lights. One comes on in my car, I take it to have it ran for free at and auto parts store just to make sure it's not a loose gas cap or something, just to get an idea of what I'm looking at, then go and make an appointment to have to hooked up to a diagnostic computer to track down the problem. Good luck, and hope this helps save you some time and money.

engine light comes on and off, these are indication that there is some
error code stored in your vehicles ECM. The engine module computer
needs to be scanned. These will give the code and as per the error code the
further problem can be detected and confirmed. The engine light
indicator blinks or remains steady on dash when engine computer
noticed any problem with any engine electrically operated components.
more help, I suggest you to refer the help links provided below. These will let
you know more about which areas to look, check, when there is engine light
coming up on dash panel.
