i have an 89 pulsar 1.8L dohc
and for a few days it would bog if i got hard on the gas taking off, but once i was going it would be fine if i pressed it. if i took off slow then slammed it down it would be fine also.
then one day it just died, everything seems fine, but there's no spark at all.

yeah i no what you mean ive got a 87 pulsar 1.8sohc. sometimes it feels sharp but then its just flat as a tack. im lookin into it at the moment, i think its something to do with the ecu. does your ecu light ever come on while your driving? that could be the problem, when my light comes on it tends to missfire. how much did it cost to convert your car to dohc? im lookin at doing the same

it could even be something as simple as a blocked air filter or oxygen senser

I'm from australia, N13's came with different engines here (GM believe it or not!) but the common problem here is the ignition module in the distributor - my friend had one die and killed all spark completly - could be a different problem to the original problem I reckon though.
As for that original problem - my thoughts are fuel blockages - try changing filters, injectors, etc. also check that the pressure is OK coming from the pump - the ECU opens the injectors full for a short period when you thump the throttle so if there's not enough pressure it can lean out and die.

yeah your pretty much spot on with the ignition module, because i changed the lead that goes to the distiributer a few weeks ago as the engine was stalling and simply wouldn't start unless it was jump started. looks like a new ignition modules on the books! thanks

Yeah, your all wrong, I've done it all, and nothing works. The problems lies deeper than everyone thinks. Could someone please respond that knows, not thinks what where the problems lies.
