First of all, when the car was boosted on the stock engine it ran perfect except for the fact that it wasn't tuned properly. Now it has a fully built bottom end with je pistons, eagle rods, new crank, acl barings, and sleeves. The compression is 9.1 and the head was rebuilt also. The car wont stay at idle.... it keeps shutting off and for some reason when i plug in the hondata s200 i cannot get the car to start it wont send fuel. prolly because of the immobilizer, but i'm going to get it re-tuned soon, but what im wondering is what could be causing this.. i know it could be a lot of things but from what i found out from the diagnostics

compression is 160 all across, it has new everything like plugs, dizzy, plugs, injectors, fuel rail, ect. vacuums aren't as strong as it used to be they're at around -10? vac on my boost gauge and used to be around -20 with the stock engine...... somebody help me out please.... im bout to just give this damn car away because of all the **** that keeps going wrong with it one after another.....

 

vac leak?

 

i've looked everywhere!!! no vac leaks that i could find..... or my mechanic lol

 

Vacuume leak. Or a really messed up tune... Do you have a wideband?

 

could be in the tune, what tune if any are you running in the S200?

 

Once you are running an obd1 ecu system there is no more immobilizer, so that is not your issue.

1. Check to make sure your timing belt is on properly at top dead center.
2. Check to make sure your not throwing any codes.
3. If your still having issues, take the car to your local dyno tuner, things like this can be figured out in person within a few minutes.

 

nooo..... im running my stock obd2 ecu in it...
i'm saying it won't start with the obd1 hondata s200 in it
timing is correct, and it was throwing a code but i forget what it was..... ohhh O2 sensor wasn't reading enough air or sumthing because we didn't finish welding the exhaust.
