Hey Guys Thanks For Helping Out,
I just finish dropping a ZC DOHC in my EF Si.
i have come to a stop and am need of guidance.
i have looked at all possible problems to solve this error.
The car Cranks but wont turn over.
i have fuel, air, and a spark.
when the car is cranked i hear some backfire soo i think...
I've check my Firing order and is good 1-4-3-2 (new spark plugs)
i've change timing belt and did a timing adjustment to perfection. lined the block to the craNk and the pulleys in the center.(as explained on this site)
i am frustrated but i understand this is all part of swaps :sly
i am lost and dont know what else to do

Firing order shouldn't be 1-4-3-2 3 and 2 are paired cylinders... the cant fire back to back. should be 1-3-4-2 or 1-2-4-3, Thats my first guess. unless its just a typo. get back to me

i had that same problem...i ended up having to change my dizzy....turns out that was the problem even though i was getting spark with the old one...some internal problem

check your order on the distributer, if you are 1 plug out it will crank and sputter and backfire.....make sure you are 1432 from d ( i think bottom left corner of the distributer)

As I said earlier 1432 is also an improper firing order since both 1 and 4, 2 and 3, are paired cylinders and cant fire after eachother...

The problem with this car has been fixed. it turned out to be multiple things, it didn't fire because no cam sensor was wired. Their was also no coolant temp sensor wired..

its his cam position sensor ... im preaty sure he swaped from a sohc to a dohc ... u have to change the cam position sensor
