I'm having a problem that I can't pinpoint. I desperately need some help.
I swapped a '91 7MGTE into my '87 NA recently. It fired right up the first time, dorve it for a while, until I went to get some food. When I tried to leave, the car wouldn't start. I checked the EFI fuse, grounds under the intake manifold, and coil pack ground. All are good. I test for spark and only the 2 and 5 coils are firing. I bought a new coil pack and put it on, drove it around and blew the stock ct26 at 20psi. I put on a 60 trim, and drove it around, when i stopped at the same food place (maybe just bad luck) it won't start again. Only 2 and 5 coils are sparking. There seems to be a backfire every now and then.
What would cause the car to run, and then not? Each drive was only about 12 miles. Is my wiring wrong, and I'm killing the coil pack? Can the CPS lose its setting and need re alignment, because it hasn't been touched since the HG job and the car ran for thousands of miles after that without a problem. Faulty ignitor only firing 2 and 5 coil?
PLEASE HELP!
