I am still having troubles with my 90 3.1L RS

I now have good fuel pressure (o rings where shot)
But now it will bark once when you first try to start it but it will not run
just crank and crank

If you try to start it once when turn the key all the way back and try to start it again and do it once more the security light comes on and stays on but will disappear if I leave it alone for a bit and when I get back to it it will bark once again and then just crank.

I do not have a key with a pellet in it but to make a long story short it was given to me and there where no keys to it and a busted switch but had a new (used)one in the back seat so I put it in so I had a key( no pellet) instead of a screw driver) After getting it home I was able to get it to run but I would have to constantly feather the throttle. was told it had a bad injector so I changed them and know just the bark as described above.

any Ideas
Vats not firing the injector?

oh it has fuel in the tank, plugs and all are good and hooked up right.

thanks again all
and sorry to be such a bother new to fuel injection ok anything newer then the mid 80s

1. You need to search from the tech answers on the home page about VATS. If you don't have the chip key, you aren't gonna run unless it's been bypassed already.

2. My 90 3.1 bird did that when the coil died. It was throwing a spark when I would check but wouldn't run. It wouldn't fire under compression, though. I only found the problem by accident in the dark. We could see the spark literally come through the side of the coil and ground out into the coil bracket. A new coil and I was on my way.

Good luck, and welcome to thirdgen.org!

 

My friend just had this exact same problem. Turns out his rotor hadn't been changed in 4 years. It had eventually wore down to nothing on the tip and over time fouled all of his plugs at the exact same time. After a complete tune up hes up and running again. Check to make sure you have spark at the coil. If not I would start there. If so then check all the wires to make sure you have spark to them. That would pin point possible cap and rotor.
