Thanks to some excellent threads on this message board, I think I need a new fuel pump but I hope someone confirms this.
I already had figured out that I get spark and since the engine is cranking fine, there seems to be a problem with fuel delivery. I read that with turning the key to the ON position, the DME relay turns on the DME, and then after the DME detects that the engine is cranking, it sends a signal to the DME relay to send juice to the fuel pump through fuse 34.
So... since at fuse 34 I get zero volts before the engine starts cranking, then 12 volts when it starts cranking, this means that the fuel pump should be getting juice yet the car doesn't start. (I was thinking to connect the fuel pump directly to the battery as a test, but it's so tight under there that I can't get with a wire to the + port of the pump at all.)
I should probably take a fuel pressure reading just in case but I don't know how. I have a pressure gauge kit but I don't know where to connect it. Can someone tell me how to use this thing, or should I not bother and just buy a new fuel pump (90 something K miles on the car)? Also, is there a good step-by-step description for changing a fuel pump?
Thanks a bunch, I would be completely lost without this forum!!
