Need Help no running ZR1 - Page 2 - ZR-1 Net Registry Forums

One of two things:

As Jerry said, check the ignition module pins, that may be the problem
You mentioned no ECM codes, did you check CCM as well? If you put a battery booster on the car and then tried to start, you can fry the CCM and this would cause a no start.

Also check the plugs behind the coil packs.

Band pin had also happened to me and i was pulling my hair for a couple of hours

I put the main connector, the longest or largest connector, at the back face of the ignition box on upside down and bent one of the pins and I had to pull the plenum to straighten out the pin!

Only thing was I had ignition function. The system went into some kind of limp home mode. The motor would start & run but it sent a code 41 (?). I would have to say maybe one of the small plugs at the front of the ignition box maybe the issue here?

Hello Guys
i have look at all but i cant find a problem
the pins are all straight and the plugs and connectors are all
in the right position and i find 2 things yesterday
the map vacuum line has a small crank so i change it
and the positive pole from the Battery was not real strong
i can move it with the hand so i take new battery bolts
the old was not in the best condition
but it is still the same maybe it is the ECM but i have no
trouble code in the CCM and the ECM
i have no spark
and the fuel press is OK the pumps work
so what do you think shod i look for a new ECM
manny thanks for every help
thanks
Jochen

Glad to hear that, Jochen! Was it a bad connection, or the sensor?
