Default No Fuel / No Spark Bank2. Bank1 Normal

I have confirmed that Bank 2 (pass side) is getting no fuel from the injectors and no spark from the coil pack. My car is running on the 4 driver side cylinders only. Do you have any idea what might be the cause? This all started from swapping my 78mm intake and TB to a 90mm intake and TB. The TB is off a LS2 so I had to cut and rewire the TPS and TB motor to a single LS2 plug. I verified TB operation after the rewire was done. BTW this is on a C5 so it is drive by wire. The only codes I am receiving are for the coil pack.

P0352 - Ignition Coil 2 Control Circuit (Pending) (Immature)
P0354 - Ignition Coil 4 Control Circuit (Pending) (Immature)
P0356 - Ignition Coil 6 Control Circuit (Pending) (Immature)
P0358 - Ignition Coil 8 Control Circuit (Pending) (Immature)

The only thing that comes to mind is the PCM got fried? I am puzzled why Bank 2 is dead.

Here is the link to the thread on how I got to this point. https://ls1tech.com/forums/showthrea...6&page=1&pp=20

What's up man...It looks like you are making progress. Ck the IGN fuses. Is the 2step still hooked up?

Thanks for all your help in the other thread. All fuses under the hood have been checked. I even replaced the IGN fuses with new ones just to be sure. The 2 step is not hooked up. Also FYI the coil packs use the same fuse as the injectors so they are tied together. It would make perfect sense if Bank2 fuse was blown but that is not the case.

Have you had a chance to put a voltmeter on it? I would at least compare what you see across an injector plug and compare that to the other bank. I'd also check w/ the voltmeter on a good ground if you don't see anything on the bad bank. Don't know if it's been mentioned already but there are ground wires at the back of the heads that should be confirmed as secure.

**Fixed** AVB you were right. The ground for the coils and injectors on bank#1 and bank#2 is Chassis ground G-107. It is located on the back of the drivers side cylinder head. There are two black wires that terminate in one eyelet that is secured with one bolt. One of the two wires was broke from the connector. All this trouble over one bad ground. I went ahead and pulled the intake to make fast work of the broken wire. She sounds much better running on 8 instead of 4 cylinders.
