Asked by for the 1997 Ford Explorer
is it a cranks no start concern,or are you having a concern with a normal crank speed but no start?we have had concerns with everything from batteries,ground cable at block loose to fuel pumps dropping pressure.
where is the ground cable at on the block but battery fuel pump is good
it is on the left front part of the engine,you will have to get under the vehicle to see where it attaches.
