90 Spider with Motronic. Had the injectors cleaned by OK Injectors, installed new cap & rotor. Installed new carpeting. Now it won't start. Checked spark & the plugs are firing. Followed some advice here such as fuse next to ECU. Question: I find only 2 grounds under the parcel shelf. Are there more hiding somewhere? It is mentioned that the fuel pump must be grounded. Is it one of the 2 black wires that are under the shelf behind the driver? They are identical. I'm worried that I missed something when I installed the carpeting. Any help will be appreciated. Thank you.
