I use to run a b18b swap in my car. I converted to ls/vtec. now I get a check engine light and no injector pulse width in number 4 cylinder. I tried hooking up the pbd2 scanner to see what codes I would get. I couldn't get linked with the scanner. I even tried to do the jumper to get the codes but no luck. I even tried a different ecu. Any ideas?

 

hmm, that's odd. Could potentially be a bad injector, or faulty wiring.

What injectors are you using?

 

I'm using GSR's. the injectors are good. I tested them. how could the wiring be messed up? I didn't mess with the wiring. It ran fine with my b18b.

 

also lets say its the wire that somehow got messed up which I know it didn't. Would that cause the check engine light?

 

Yes, that will not complete the circuit to make a spray into the combustion cylinders.

The #4 Injector uses 2 wires. A Yel/Blk wire which is a positive source (at A25 pinout) and to the power junction harnes (which is located near the brake master cylinder), and also a Yel wire that leads to A2 (assuming you are OBD1).

Check wiring with a Digital Multimeter

its obd2. so it would set a cel? umm I just wanna burn this car
thanks for the help poison.

 

np. I hope you get it fixed man. Just remember it's fixable and you'll love it when you fix it.

 

also wouldn't an ignitor do the same thing? but then it would be all injectors huh?
anyone else have any ideas?

 

If the ignitor went out, then none of the cylinders would fire.

It COULD be the cap, or the wires, or also a fouled up plug on the #4 cylinder.

 

I changed all that so I guess it has to be the wiring somehow even though I don't know why its messed up

 

also I almost forgot. Would a bad wire make me go into safe mode? its doing that(safe mode)

 

Yea. Most likely a bad injector or break in the wire.
