Re: help w no start want to test tbi

Make sure you have spark at the plugs first. I had the plug wire from the distributor to the coil come apart at one end and cause the car to not start.

Next I would install a fuel pressure test port fitting at the back of the throttle body and make sure you have fuel pressure.
