its starts but does not want to run. i have checked the timing and its in time. any ideas as to what could be causing this. also i keep blowing three fuses for some reason and i cant figure it out either. the hazards, the wipers, and the turn signals, ive gone over my wiring and everything seems to be fine any clues?

well i worked on it today some more and im not sure what is the matter. i think i have hooked up everything correctly but it doesnt want to run. it starts but will idol very rough and cut off, or it will rev up but not consistently. i noticed today though around the turbo there was smoke. i think there is a intake problem or the MAF sensor has gone bad. if anyone has any other ideas please help.

i noticed that im using a SOHC MAF, does that make a difference in the air flow? should i be using a DOHC MAF from a DOHC KA or Z32?

The SOHC MAFs is the one you want, you would need to retune for the others, Im guessing the smoke is just oil burning off the exhaust. It sounds to me like you should check the MAFs voltages, also check the TPS.

alright what should the MAFs be getting in voltage and what is a TPS?
