alright i swapped the engine went in no problem. im using the p28 ecu ive wired up the the mpfi but my injectors are not firing.fuels going through the rail.i used this conversion harness from xeno chrone i have no clue what the problem is

 

i sorta feel dumb cuz ive been looking a litlle harder and i think i might have it down but ill have to see tomarrow

 

if it still doesnt work.... check your tps, did you switch the white and the yellow? the new tps position is upside down!!!!!

 

yea i just tried that and nothing my map sensor wire might have a short could that be a problem??

 

maybe..
just a thought, did you check the dizzy and plugs?? got spark?

 

i have spark when i sprayed starter fluid in it and it stayed running for as long as i did.. i stayyed out all day trying to figure it out.do i need a four wire o2 sensor?? when i got the motor it came with a 1 wire.

 

maybe you do, however that would not effect fuel reaching the cylinders....
first i would test the wires to the inj's , and double check that you have the sequence correct..
what manifold do you have??? stock??

 

its all stock i did some testing and im not getting anything to the injectors but ground

 

you've been holding outinfo..... i noticed that i replied to more than one post from you...
how did you go about the dpfi to mpfi conversion?? did you install a resistor box???? because you definately need one. dpfi all four wires from ecu go to inj's, 2 each.. mpfi is one wire per on inj from ecu, and the other four wires come from the resistor box, is this how you did it??

 

you know what ive been lookin and looking and from what i gathered from most these people that i didnt need one but your telling me i do need one.well do you know what ohm the resistor box is??no junk yard around here
