i have a 92 hatch obd1 and i just put a b16 head on my ls, b4 i did it i got the whole ls vtec kit, ran the oil line and all.and oil pan is fine, so any ways i have everything on and i ran the vtec wires and for some reason i have no vtec. i tried my friends solenoid and still no vtec. i am throwing a check engine like for code 21 which is for the solenoid...so can anyone help me out?

 

I might sound redundant or retarded here...but check the wiring from the selonoid to the ECU, that's most likely your problem if a known working selonoid checks out.

 

ya do you have the wires going to the right spot in your ecu also check your ground from the solniod to man you allso may have a problem if theres no pressure switch its just the solniod all depends on what ecu your runing and if its chiped

 

I had this problem and I had to put in a bigger guage ground wire from one of the wires coming out of the ecu to the body. I forget which color wire, but i ran one one straight to the solenoid and just grounded this one

 

we wired it into the harness because all 92 egs have vtec already ran to the ecu but after it didnt work we ran it straight to the ecu. my distributor timing is exactly in the middle. also we tried 3 different grounds. groundsed on the solenoid, tranny, and the frame. i just heard from a friends that i have to take my head back off, because i have to drill and tread on another spot on my head. so oil can drain out... is this true

 

no you just plug that one hole it drains with all the other oil, test you solenoid by running 2 wires to the battery, you will be able to hear it click open. If the solenoid is good it can only be a few other things

 

yes i plugged that oil hole on the bottom of the head and also i tested the solenoid and it was fine... and i purchased a p28, still no vtec

 

any takers? also would i have to bypass or block off a knock sensor? if so how?

The P28 doesn't look for a knock sensor.

 

what could be the problem?
