Motor Install Prob

[s10quinn]

Hi,

I just dropped in an '87 2.8L Throttle Body Injection motor into my 86 2.8L TB injection truck (86 S-10).

I got to run the new motor before it came out of the wreck. Ran perfect.

I didn't pull the motor but everything looks right.

I reinstalled the motor, hooked up all connections and tried to run it. I can smell and see lots of fuel going down the Throttle Body.

I have pulled three plugs and they all have great spark.
The distributor has NOT been removed or adjusted since coming out of the wreck. The spark plug leads are in the right order.

Any ideas why I have fuel and spark but no Fire?

I even tried a little Starting fluid down the Throttle Body and still no fire.

Is there a chance my '86 computer won't run an '87 motor?

Thanks in advance.

Might be a bad sensor had the same thing fuel and spark but no go temp control sensor was bad
