I have intermittent starting issues, any ideas?

What is your question?

1990 Toyota p/u 22RE. New starter, new battery, new cable ends, new ignition switch.....for the most part It will start but every now and then it has left me stranded. When it does I can push start it and it will start by the key for some time after!

How long has your 1990 Toyota Pickup had this problem?

Since I got it 2 years ago
