This car will die and not start for several minutes. We've changed the coil, distributor cap, plug wires, ignition switch and key switch. The mechanic checked the computer and no codes are showing. It is doing better but went to the store the other day and came out the car took ~5 minutes to start. All of the other electrical componets still work. It's like the power to the ignition only is interrupted.

Hello

First when I look up your car there is a convertible, coupe, and GTS. All of these have 4 cylinder engines only. Also, there are several different types of 4 cylinder engines. So please make sure if our suggestion doesn't help and we need to discuss it more include the other data.

With that, I see you have accomplished a lot of work. I don't see where you have checked the fuel pressure to see if the pump is working correctly, the filter is clogged or the sock is obstructed etc. I have attached directions for that.

Fuel system pressure must be released any time a fuel line is to be disconnected.
1. Connect fuel pressure gauge C-3292 and hose adapter C-4749 or equivalent to fuel rail service valve.
2. On 1984-85 models, start engine and observe pressure gauge. On 1986-89 models, using ATM tester C-4805, place ignition switch in Run position and depress ATM button to activate fuel pump. Gauge should indicate 53-57 psi pressure. If pressure is as specified, remove gauge and adapter from fuel rail.
3. If fuel pressure is below 53 psi, install tester between fuel filter hose and fuel line and start engine. If pressure is now within specifications, replace fuel filter. If pressure does not increase, gently squeeze fuel hose. If pressure now increases, replace pressure regulator. If fuel pressure still does not increase, either the fuel pump is defective or the filter sock is obstructed
4. If fuel pressure exceeds 57 psi, remove fuel return hose from pressure regulator end. Install suitable length of hose to pressure regulator and place open end of hose into a clean container. Start engine and recheck fuel pressure. If pressure is now within specifications, check fuel return line for restrictions. If fuel pressure is not as specified, replace fuel regulator.
