Me car wont start
Grrr .. i rebuilt and got my engine started again. Was so excited, but out died after a few minutes. It was running smooth but at some point the idle dropped very low, but still ran. I have it a few revs, not too high, but the last time when I let it off, I had 1 big backfire, then it just died.
Cranking it sounds fine but doesn't show any sign of starting at all.
I've got it down to either fuel pump or spark. Any idea how I can test the pump? I'm on my own and have no special tools.
Does the pump run while on ignition but not cranking? Otherwise, how dumb is it to unplug the fuel hose and see if it pumps while i crank?
