Are you being obtuse on purpose? Pull the codes and tell us what they are. If you don't know how check the last sticky at the top of the forum.

check engine lite on won't flash and scanner won't scan

Jump the service connector then. If you cannot pull codes we can't really help you much. Especially since getting info out of you is like pulling teeth.
Check your timing.

badek9

jumped the service plug and nothing

WHat do you mean "nothing"?

Is the cel off or solid when you ground it?

badek9

lite stays solid

Prob bad ecu if your sure your jumping the connector right. Have another ecu you could try?

When the key is turned to the ONII position it stays solid? Are you sure you're jumping the connector correctly?

badek9

yes lite is on solid with or without jumper

Swap ECUs.

badek9

aside of a bad ecu any other suggestions

Inspect the inside of the distributor and check the mechanical timing.

badek9

inside the distributor looks fine but from looking on the web saw other cars with same problem being a bad distributor

Former User

Is the inner cover missing?

grumblemarc

iTrader: (4)

Still hasn't checked timing?

badek9

inner cover is still there and how can i check the timing.maybe the car jumped timing

Since the search function on your computer isn't working either, it sounds like time to spend $20 on a Chilton or Haynes manual.

bogs hard if you don't let of it stalls
