Do you have an ignitor you can try swapping out too?

 

Did you use the ECU from the new engine? I forget the specifics, but some of the engines changed the tick marks on the cam sprocket that the cam angle sensor reads, though I'm not sure that would cause your particular problem.

Yes Im planning on doing that tonight, and possibly ohming out the wires from the coil pack to the harness connector and compare to the 97 engine???? I did not get the ECU from the donor... thanks for the response!

that's a straight forward swap - you just take one engine out and put the other in. the issue is not related to difference in years of the engine.

 

swapping coil and igniter sounds like a really good deal.

 

which intake manifold did you use? you could try swapping that if all else fails in case the fuel system, injectors are hosed on the "new" unknown engine.

Swap the plug wires (1 to 3, 2 to 4).

 

Did you install new plugs?

 

See if the problem follows plug wires or stays with coil.

 

I have a good ignitor here if you need one PM me.

Always use the intake manifold and parts from your original engine to prevent issues like this...

Thanks for the response, I borrowed an ignitor from my bro-in law, fixed the issue! You have a good ignitor for sale??? how much?
