Welcome to the forum

No, not a "brain" problem.

1994 spark is run by the ICM(ignition control module) located on the front of the lower intake, these did have issues, but can be tested at most auto parts stores.

These Lima engines use a Timing Belt, which needed to be changed at 80k or so miles
If you don't know when it was last changed then it could have stretched and has now slipped so cam and crank are out of time.

Compression test will tell if that happened or if a valves rocker has slipped off, another issue with these engines.

 

Hey Ron thanks for the advise i went and checked the timing was rite on the mark i think its the vacum i didnt have any vacum both vacum lines wer shot ive got fixed ill try starting tomorow to see if it was a vacum leak
