Check for a blown PDC fuse 1 (30a), and try swapping your ASD and horn relays.

All fuses look good.

Swapped relays and it made no difference.

I can hear the fuel pump.

Will it start if you remove the ASD relay from its socket and install a wire jumper from terminal 30 to 87?
How are you checking for spark?

Have absolutely no clue what or where terminals 30 & 87 are.

Spark checked via screwdriver method & using a spark plug.

I fear it is time to go to the shop....

Unplug the VSS sensor in the tailshaft of the tranny and see what it does then. If it does start and run then change that sensor.


Do you know what was good about the good old days? I wasn't good, And I wasn't old!

Senators and Congressman should wear uniforms like NASCAR drivers so we could identify their corporate sponsors....
