Hello,thanks for posting
You can check for injector pulse voltage using a test light made for this, it's usually called a noid light which fits into the injector connector, the light will flash while cranking the engine if the computer is ending the on/off pulse voltage, you can trey using a regular 12 volt light but it may be too dim to see. For now turn the key on and use a voltmeter or test light to see if one wire to the injector shows a voltage of about 12 volts,if there is no voltage there may be an open wire in the injector harness, if there is voltage the next step would be to check for injector pulse.
Thanks for the reply
Now we.ve pretty much ruled out everything except maybe a large intake air leak at the #1 cylinder, the exhaust glowing red is caused by a very lean mixture but it doesn't seem to affect all cylinders only #1, have you checked for a possible intake manifild leak, possibly a gasket leaking, do you happen to have a vacuum gauge to check manifold vacuum.
As far as I know this has the 5SF-e engine and has no distributor and has two coils and wires is this the case?
