Wanted BCM 1990 Zr1 - ZR-1 Net Registry Forums

JT_n_CT_90_ZR1 · 2 Weeks Ago

I am trying to get my ZR1 to crank over, I have literally changed every single thing including sensors and ECM. The only thing left is the BCM. My VATS us 15. Please tell me someone has some info on where to buy or any other options. This car only has 30k miles in it. I take manifold was pulled and vacuum lines checked. Installed new wires and coil packs. I?m getting desperate.

Does it crank ?
Check the relays under the dash.
Under the steering column.
It will let you think that you have a vats problem, but it?s a bad relay.

It doesn?t even crank. Before I did anything the check engine light wasn?t coming on, then the digital dash started flashing ?system? (I think that?s what it was flashing) then the gauges went out, the car started running HORRIBLE, climate control started flashing every button I hit, and the information system went bonkers and illuminated everything BUT check engine.

ODDLY the radio and antenna still work.

Ohh and the parking and fog lights wouldn?t shut off but dimmed to like 15%.

I do not have any thing to help, except you should get the FSM for your car
ZR-1. Also check solutions in the zr-1 net registry forums.

Have the battery checked/load tested, check the fuseable link wires next to the battery.

Check the purple wire to the starter and see if it gets power when you turn over the key

Like tpr60 said, check battery and terminals.
Have the battery load tested.
Check you?re ground wire to chassis and engine.

I can reprogram any BCM/CCM to make it correct
