ok here i go... first off i wanna say hello to everyone and any help is greatly appreciated.

im doing a k20swap for a friend of mine... im having a few issues with the car... car turns over but has no spark or fuel.... the ecu is from an o6 rsx ''manual''.. i work for a acura dealer so correctly programmed the key to the ecu.. no flashing immobilizer light.... i checked all grounds and connectors? and still no spark pr signal to the fuel pump... my question is does it matter if he uses the type s engine wire harness? the connectors for the ignition coils are blue and an extra plug by the vtech solenoid ''round two pin has no sensor? also missing connector by the imrc valve ''an emission solenoid''?

ive checked almost everything and still cant figure this one out... oh yea it has several codes ''p0107,p0118,p0122,p0113, p2469,p0600,p0498.. try to clear them and they come right back like theres an open in the engine harness... the harness was brand new?

if you put your starter on wrong it would just spin and have no spark like that (happened to my friends sr20 240) and check all of the codes i dont feel like looking up all of them but if its throwing that many codes than thats most likely your problem.

starter hooked up wrong? it only has two wires running to it?

u mean the two wires running to the fuse box?

if its on backwards as in the starter on backwards youll just hear a whining noise and it wont turn over. if its actually turning over and starting up and then dying it can be a number of problems. check the codes. you could also have a bad vacuum leak. it can be a number of problems. what are most of the codes describing?

the car turns over jus wont start? i checked for spark and none... and checked for fuel and none? the starter was already installed with the motor? the codes are all high input codes and low input codes? i clear them and they come right back?

P0600- I think you blew the multiplex unit.

here i was bored...

P0107 Manifold Absolute Pressure (MAP) Sensor Circuit Low Voltage
P0118 Engine Coolant Temperature (ECT) Sensor Circuit High Input
P0122 Throttle Position (TP) Sensor Circuit Low Input
P0113 Intake Air Temperature (IAT) Sensor Circuit High Voltage
P0498 Evaporative Emission (EVAP) Canister Vent Shut Valve Control Circuit Low Voltage
P0600 Multiplex Control System Troubleshooting
p2469 wasn't on the list

yes i have the codes... but once i clear them they come right back? u think its a ground issue..? i checked all the groungs and they are fine?

Go over the entire harness and look for pinched wires. Most common problem that I've seen.

The codes will come back if something is still wrong, you can't just clear them you need to address the problem. Like Lazlong said though, its probably a harness problem pulling that many codes.

is there a possibility that it is the wrong harness? i mean there are a few models of k20 out there now, is there any difference in the harness of an older k20 or a new one, a k24, or civic si or rsx/rsx-s? or do they all use the exact same harness?

it sounds to me like you have a harness problem as i highly doubt all of those things are bad on the car....i would personally take the harness out and go over it wire by wire to make sure there is no cuts or breaks and also make sure that is the right harness but yea it doesn't matter how many times you clear the codes if you dont fix the problem the codes are gonna stay on

get k-pro and disable multiplexer and disable emissions u are going to want k-pro anyway

 
Rep Power: 234

I would love to do that if it wasn't for those pesky emissions standards. Do you realize that only 3 states have emissions at all. And of those 3 Cali is the only one to implement state wide. We have 254 counties in Texas and only 9 where they have an emissions test.

u will pass emissons with k-pro even tho u disable the emmisions the car doesnot throw any codes or check engine light so u wont have a problem

Almost makes it seem worth the $1500.

I don't see how you could pass emissions by adding k-pro unless you use it to map a very low power setting, since they hook you up to a four gas analyzer and measure your exhaust emissions.

Here they just hook the inspection computer up to the DLC and let the car idle when comp says, rev it when the comp says, the do the safety check (brakes, light, etc.), and send it on it's way. 10-15 minutes tops, $45. This is for OBD-II ('96-newer).

1995 and older they either do 4 or 5 gas, or dyno. That one is $13!

same here, but i'm scared they might hook me up next time because i have the megnaflow muffler on the back now.

with k-pro u can run open loop and tune the idle and part throttle sections lean like idle at 16.0 a/f and light throttle at 15.7a/f u will pass no problem then when u leave switch back to closed loop

 
Rep Power: 284

I always get put on the dyno with the gas analyzer.

****! mindbomb, do you have a stock cat.? mines high flow, hope i'll still pass. i have no CEL so i'm guessing my gas levels are in the legal wrange.
