the engine immediately shut off but lights were still on & bright, horn works, radio etc. But now the truck won't start. The gage shows in the - now, first tried a jump, then replaced ignition coils and some relays that had burn marks on prongs, but it still won't start. have checked fuses, it has gas (also primed it) still won't start. other electrical work ok so it's not the battery. it cranks but just doesn't start. what should i check next. my only form of transportation and need to fix a.s.a.p. appreciate the help / ideas / suggestions...thanks
what do i check next??? going to pull the spark plugs but i don't know what else to look for.
