Diagnose this (possibly) simple no-starting problem
1999 XLT 4.0 113,000 miles. Truck ran fine yesterday when parked. Get in this morning to go to work, starter cranks and cranks but engine will not fire up. Cranking sounds normal like always. I let the truck sit for about 10 minutes, go back out and it fire rights up. Never had this problem before.
I am thinking fuel pump? Possibly ingnition coil?
Any ideas? How do I diagnose this problem if it happens again? I guess I would start by pulling a plug and checking for spark while cranking.
