Hi, I installed a Borla exhaust system on my 1990 Miata and cold air intake. The car has been sitting in my garage for about 8 months. When I went to crank it it would not start. I drove the car in. I have replaced the coil pack, plugs, and drained the fuel out of tank as it smelled bad. I installed new fuel and tried to start and it still will not crank. I have no fire going to the spark plugs, and have checked the coil's both old and new. PLEASE HELP as I am about at my wits end.

Thanks
Frank

Check Ignitor:

COIL IGNITOR POWER SOURCE (MIATA, MX-6, PROTEGE, 323, 626 TURBO & 929)

Ensure coil and power source are okay before checking ignitor. Disconnect coil ignitor connector. Install Ignitor Checker (49 F018 002) and Adapter Harness (49 N018 001). On Turbo models, use Adapter Harness (49 H018 910). Connect the ignitor checker and adapter between the ignitor and wiring harness, connect the power leads to the battery.

Turn ignition on. Disconnect the high-tension coil lead from the distributor and hold it about 1/4" from ground. Flip the SW2 on and off, and verify a strong Blue spark is discharged from lead. If spark is weak in color, replace the coil. If no spark is present, check battery feed, main fuse, main relay No. 1 (MX-6 and 626 models), injector main relay (929 models), ignition switch and fusible links. Repair or replace as necessary.

Also the crank angle sensor
