Well i have been working on getting my 250 started and it wont turn over fast enough it turns over slow but not to slow just slow enough not to start we went and had the started tested and it passed battery is good anything else?
are the battery cables in good condition? do the ground cables have good contact? is there paint under the engine ground cable?
if your distrubtor timeing is to advanced it will have a hard time cranking fast. try disconectiing the coil wire and see if it will crank faster. if it does then you know thats your problem.
yep that (timing way off) will load your cylinders full of fuel and it builds too much pressure and not enough relief.
Yep, the starter on my grandpa's '78 Bronco Ranger XLT was like that. It was turning over too slow to start most of the time, and drawing a ton of amps under load, would run the battery dead in extremely fast.. Tested fine when it was off the vehicle...
True Dat' A motor (starter motor) under load will certainly act differently then one that is just free-wheeling on a test bench
+1 i took one off one time had it tested they said it was good i told them i would put it back o my car and push start it to get it back to them and when it would not start they could change it so then they gave me new one it was on a 78 mustang2 like a 45 min job
