FORD F-150 SPARK PROBLEM

1991 Ford F-150

My 91 fordf150 with a straight six won't start we checked the spark plugs coil pack and fuel pump and filter when you try to crank it starts to but then it just keeps turning over any advice on what could be wrong?

How long since a tune-up? Any applicable trouble codes? If it cranks good but won't start, have a helper crank it, while you visually check for spark at the spark plugs. If you have spark everywhere, use a gage and check fuel pressure.

What is engine litre size? Do you have a distributor on this? I know ford had lots of problems with tfi module, where applicable. Don't replace that without narrowing the problem down. If you have dis ignition then then you don't have a tfi module.
