My friend was trying to install a vafc on his prelude and when he put the ignition switch on the check engine light was on and we checked for CELs and none came up...what coul be happening here because he took out the vafc (didn't splice any wires so the cables are intact) and the caro won't start now. Can somebody tell me what could be wrong?

 

you did something to the ecu while you were installing the vafc.. no cel blinks = ecu problem

maybe you didnt put all the wires together or something

 

we tested the ecu on another car... worked perfectly

 

anybody who can help please

 

Re-check all your VAFC wires, make sure you hook them up right to the ECU

 

he took out all the wires from the VAFC and doesn't want to install it he just wants to get the car to start.

 

Yea i put mine on myself and just this past week i was driving and it died it has NO spark i dunno what happened i dont think it was me ecu or vafc cuz its been installed over a month works like a charm

 

but did you get it to start?

 

when i first installed it yes but the other day it jus died out i dunno wat it is, i have no spark at all..but double check your connection right make sure no wires are in the wrong place...

 

does the vafc turn on if the vtec wires are not connected?

So he took out the VAFC harness and try to start the car without VAFC? Did he reconnect all the wire that he cut from the ECU. Because when installing VAFC, you have to cut VTEC selonoid signal output, and Pressure signal output wires.

 

yeah he did put the wires back together

Does the engine turn over, trying to start? What yr is the Prelude?

 

yes it does ... its a 94 prelude...ecu is p14

 

Just found out the car has no spark at all and fuel pump is not activating...i think this is an electrical problem...???

one word BOOMSLANG. stop whoring up your wiring, get the jumper harness, plug and play. 130 bucks now, or your car not starting for who knows what?

 

Did you happen to mess with the ignition coil switch? If that isn't connected im pretty sure you wont get spark or fuel.

Hey, I just talked to one of my friend about this problem. I remember he had same problem b4. Check engine light on constantly, no code, no spark, no fuel. He figured out because the Map sensor wire got grounded somewhere. He fixed the problem. Make sure your buddy reconnected all the ECU wires good. Tape them up good also.
