    older carburetated mercruiser 5.7 hard start

    i remembered while i was using my multimeter to test for 12v while cranking. the only way i would get a reading is. with the red probe on the positive on the coil and the black probe on a bolt on the engine. not on the coil. shouldnt i get 12v probing the positive and negative of the coil.

    Rochester quadrajet carb. How many pumps do you give your engine at the throttle to get it started. I put a spark tester on the engine and the spark wasn't very good so I took the cap off and this is what I found. I ordered a new pickup. I cant get a serial number off the engine it is very tight...

    Alternator questions

    the engine that has the bad alternator has the power steering pump. I guess in the spring I will have to chase wires on both engines and se which engine is doing what.
