Thanks to all who shared their expertise related to my fuel problem. I have progressed to the point where I have learned I have a NO SPARK issue. To resolve my starting problems, I have replaced the fuel filter with no appearant improvement. I did check the fuel pressure at the fuel rail and I have 36-40 psi with the engine not running.
I am now focused on the spark. I had my ICM checked at autozone and it tested bad. I replaced it with a new one and still no luck starting the car. I pulled the no. 6 spark plug wire and inserted a new spark plug in the wire to see if I am getting a spark. NO SPARK even with the new ICM. Now I am lost. Has anyone experienced a similar problem. I hesitate to play with the cam sensor or the crankshaft sensor. Is it likely one or both of these components are my problem? Since I am not getting any spark is it likely my DIS has failed? My wiring looks good.
I appreciate any help you can provide.
I have a 1991 SC that has been in storage for 15 yrs. I start in 2 times a year. Recently, it will not start. It turns over fine. When it does run it runs very rough and shuts down. The gas is old. Has anyone had a similar experience? What was the cause? Is it likely to be the fuel pump? Thanks for any help you can offer
