sr20 misfire troubles
 

hey guys, i just started my 180sx sr20 for the first time today since fall. around 2-3 thousand rpm the car sputters, backfires and misfires. it doesnt idle very well either. i changed the plugs, swapped MAFs and changed ignitors and nothing. before starting the car i checked the tps which was way off and changed the oil. i didnt really do alot to the engine over the winter which is why im a little confused. i cut out the boost solenoid and removed hicas in the car. also i bought a brand new alternator which doesnt seem to be charging, thats about it. any help at all would be really great. thanks alot!

u didnt run it every now and then over that time did u, u probably have fuel clogs... read the fsm troubleshooting pages... thatll help u

ya seems right, i tested my fuel pressure, only putting out about 17 psi. no fuel even coming out of the regulator
