I have a 1995 Toyota Tacoma with 2.4L engine. It was running ruff and started stalling when warm, would not restart for at least 45 min. then would only run about 15-20. Eventually quit all together, replaced crank sensor, plugs, cap and rotor. Now computer reads P1300 code and the fuel injector don't pulse. Can someone please help.

Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.


Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.

OK, do you have power to one side of the injectors?

Also, does the check engine light come on for bulb check when the key is turned on?

Both sides of the injectors have a green light, and at some point the check engine light has been removed. However it does have a code P1300.

So, what does that mean? Does it have power or not?

OK, the injectors are powered through the ignition switch so you have to trace it. You also need to try to pull codes to make sure the computer is powering up since your check engine light doesn't work..

I have already pulled the codes, that is the P1300 code that I said it is giving.

The code is for an igniter problem which means that you shouldn't have spark but that has nothing to do with not having power supply to the injectors.
