P0200 code and misfire on passenger bank LM7

[Paul Y]

Gents,

On struggle street and could do with some advice

LM7 swap into a 66 C10.

Stock PCM stock engine.

After my non start problems, solved with a crank position sensor. I have now developed a P0200 fault.

I have a Noid light which shows that there is signal to all of the passenger side injectors.

When I connect the harness back to the injector I can hear it clicking so is firing.

It sounds like the bank is firing but not as strongly as the driver’s side as when I disconnect an injector on the driver’s side there is a big drop in idle but on the passenger side it is very ‘light’.

Definitely has spark.

Fuel pressure is 58lb.

I would suspect injectors but not all on one bank.

Next check will be continuity from the pcm to the passenger side injectors.

Anything else I should’ve checking?

Appreciate your assistance.

P.
