S14 SR20det wont start after BOV install.

[p4hang]

I have a S13 coupe with a S14 SR swapped in. upgrades are FMIC, HKS catback exhaust, Q45 ignitor. here is the problem I had the swap done and was running with a Z32 MAF. Car was idling but wasnt drivable because of the Z32 maf. At this time the car didnt have a BOV yet. A week ago I installed an HKS BOV. I started the car and it was running fine (Z32 maf still installed). I then borrowed a friends S14 SR maf to see if it would run better. Installed the S14 SR MAF and got nothing. I switched everything back to the way it was before the s14 SR MAF was installed and the car still wont start. I check voltage to the MAF wires and that was not the problem. Car has fuel, spark, and cranks but wont turn over. Help me please.
