Thanks for replying, 190eDude.
The engine turns over strong but no spark. Once, when I bridged the pins to make the fuel pump hot, it operated. I can smell that fuel is being delivered to the engine during the cranking cycles; but no spark. I checked the coil after the engine died, the primary indicated about 2.5 ohms while the secondary gave me about 90K+ ohms. To rule the coil out, I put in another working coil to no avail. The new fuel pump relay I got has ten pins while my old one has 9 pins; however the part# 003-545-2405 shows its for '89 2.6, would the number of pins make a difference?
I did retrieve the code from the plug soon as the problem began and it gave me five flashes. It indicated O2 sensor, but it was replaced a few months ago along with a new aftermarket converter to pass the california emission. The smog readings were well within specs except HC at 15 mph test barely passed with a 114ppm. I wouldn't think this will foul up the O2 sensor, could it? Any suggestion is greatly appreciated.
