Ok guys i have a 00 civic hx with an ls/vtec swap(b18a1 block, b16a2 head) i have all of the wiring done correctly, but it runs like junk. Basically what happens is the car will start and run really rough it runs so rough it won't even stay running unless my foot is on the throttle lightly. I'm not sure what to do.. I've tried adjusting the distributor timing but it will only start and run with the distributor turned all the way to the fire wall if anyone could help it would mean a lot i'm out of ideas

 

Anyone?

 

Has it been tuned? Does it smell like raw fuel? CEL on?

 

cel is on and it has a p28 chipped. no it doesn't smell like fuel

 

Pull the CEL. Probably a sensor

 

Will do i'll keep ya updated

 

so i attempted to hook a scan tool up to the normal obd2 spot and it wouldn't read any codes i'm not sure how to get the info off my p28, I have a 00 civic hx(obd2a)

 

P28 is an OBD1 ecu.

 

Most likely MAP or TPS sensor issue.

Or mechanical timing.

 

yes a p28 is an obd1 ecu and i agree with the tps/map/mechanical timing... i think im going to retime it tomorrow and ohm the tps sensor out as well

 

Hey guys update on issue. I have retimed the engine it is not right on the dot with timing mechanically, but now she cranks but won't fire at all ... HELP PLEASE =(

 

You need to check the 3 basics. Timing, fuel and spark. Which one is off?

 

timing on on the money, I know im getting spark, and how would i check fuel? other than knowing if its getting fuel to the cylinder or not

 

so i know im getting fuel and spark but no engine running. Cranks acts like it is going to start but doesn't continue... ideas?

 

If you have timing, spark and fuel it should start. Have you pulled the CEL yet?

 

i have in my obd2 ecu but thats not the computer i'm wanting to run it doesn't have vtec, I can't in my p28 it won't let me

 

...did you try looking up how to pull a CEL from an OBD I ECU? It is pretty simple...

 

If you know the engine isn't timed right, don't you think you should start there?
I assume your referring to timing the cams to the crankshaft, right?

 

It's your timing bud. Get someone who knows how to time it to help you.

Also, not sure what specs your lsv calls for, but I bet your cam timing needs to be set as well, I doubt it's meant to be 0 (TDC).

 

Definitely sounds like timing

 

all my timing is correct I've checked it a few times now, but still having issues with my p28 ecu not pulling the codes

 

You will not be able to pull a code from the DLC using an obd1 ECU. There is no communication between the ECU and DLC. Best bet is to plug in the p28 and using a paper clip jump the SCS connector to pull the cel code. You will need to count the check engine lightbulb flashes. Google search " how to read obd1 honda codes " and all the information will be a click away.
