mpfi swap wont star help!!!!

[ninjardr]

OK here's the deal just took the 1.5 with DPFI out and swapped in 91 Si engine i have a couple little problems #1 no spark?? #2 there is a sensor in the back of the intake that i don't have any plug for???. the engine ran before i put it in i heard it runs great but i got nothin any help would be great.

First thing - which distributor did you use? The mpfi distributor is different than the dpfi. Second, have you checked the ecu for any codes?

[ninjardr]

ok i have the si dist. on and i am getting a code for the intake air temp sens. (10 Blinks) i'm also 99% sure my wiring is right i have checked it so any ideas i'm open for them

[FuLL BLown STD]

which ECU are u using?

[ninjardr]

I have the ecu from the si in

You may have the wrong plug on the intake air sensor. If I remember correctly, there are 3 plugs on the wiring harness that will plug into that sensor - just gotta keep trying them until it goes away. That's what I had to do - I can't remember which color the wires are for it.

[4G4D Store]

technically, that shouldn't cause it not to start though. If you aren't getting any spark a part in your distributor could be bad, or it's wired incorrectly. Is 10 the only code you are getting?

[ninjardr]

yeah 10 is the only code and i dont think anything is wrong with the dist. cause it ran fine when i pulled it. there was two wires on the dist. that looked to be the same color maybe those could be backwards. does anyone remember there being two off whit colored wires???

[4G4D Store]

Yes, there are two white wires - one is a bigger gauge wire - that's the only way to tell. You may have those backwards.

[ninjardr]

do you or does anyone else know which pin the bigger wire goes 2 if anyone knows that would really help out. maybe i will actually be able to get this car running. and would those wires cause this not to spark. thanx guys
