Why does the engine cranks but does not start on a WIndstar 2002 SE The fuel pump shut-off switch has Not been activated?
fuel pump shut-off is only usually activated in accidents/rollovers etc. Several reasons for no start. The cheapest things first are changing out fuel pump relay or check the fuse whatever applies to rule that out. These fuses and relays are almost always in the engine compartment. Next check loose connections/grouds at the coil or coils. Have access to one of those portable obd-II scanners to see if any codes are present? Oh, yeah you could also check the fuel line filter if it is not contained in the fuel tank that is. So far I have only dealt with bad relays. I havent had to change out fuel pump yet. Hope this helps.
What do you look for if engine won't start and the fuel pump and filter and starter all are in working order?
power from the battery The Battery and wires is simple and easy. If the car was seriously tapped, in a parking lot or whereever, the fuel shutoff may have tripped? Is there spark at the sparkplugs? Take a look through the engine oil filler opening, is the camshaft turning while the engine cranks? I hope it's cheap and easy to fix.
