Hello, i have a 96 civic with a B16A2 swap. (usdm Block with a JDM head) I believe the head is a year 92 or 93 have to double check but i know its a jdm head. Im having some starting issues when i try to start the car. At first i thought it was my main relay that was going bad but i replaced it with a new one and i am still having the same issues all fuses are fine.

I noticed that i have to wait about 5-7 seconds for the fuel pump to prime after turning the key on. if i don't wait it wont start, i have to wait till the engine light comes on and off. I also notice that sometimes when the car is cold i can start the engine fine on the first try. When it is warm it takes longer to start.

Is the ect sensor going bad? if so were can i obtain one for my b16 head is a jdm head.

 

advance autoparts has them, b16 jdm and usdm have same sensor. sounds like maybe a loose ground. check g101 on thermostat.

 

the thermo ground is good. what other grounds can i look for???? how many are there? location?

 

block to chassis

 

I believe there are three. Block to chassis, thermo to chassis, and head/VC to chassis.

Are you 100% sure you have a B16A2 head? It did exist 92-93, but I would find the head code just to verify.

 

Yes, the block is a USDM B16A2 because it has a vin # right under it. The head is a JDM head from a year 1993, as i read the 93 number on the left side of the head.

 

That just means it was cast in 93, that isn't the head code.

 

Were can i get the head code?????

 

It should be near the date stamp you were looking at. It's usually either a letter followed by two numbers, a dash, and another number or two letters followed by a number, a dash, and another number.

As an example, the second gen B16A is a PR3-4. The 96-00 Civic EX is P2P.
