1. The engine only starts with starter fluid-does not remain running.
2. New injector
3. It is getting a pulse signal at the injector
4. Fuel does come out of the injector when turning over
5. It seems like too rich a flow
6. Cleaned the fuel tank and installed new pump and filter last winter
7. It did fire up and I drove it around but the engine would die.
8. Don't think the gas is bad
9. Haven't tried spraying gas in the throttle body-don't think that's a good idea.
I've changed all the coils and replaced plugs and wires
Does anybody have an idea on this one? I'm open for suggestions
Thanks
MR

Start the engine with starting fluid, and immediately try opening the throttle a little. If it runs that way, the idle air passage is clogged.

Mount a little round piece of paper on a dentist's mirror (small round mirror on the end of a metal rod). Hold this in the throttle body 2" below the injector, with the paper facing the injector. Have someone crank the engine. Observe the spray pattern on the paper. It should be spraying, not dripping. If it continues to drip after cranking, you have bad injector o-rings.
