Crank no start
I need some help so I was driven home and my 89f250 5.0 L just died like it ran out of gas but it was still getting fuel so I towed it to my place and figured out that I am getting fuel and I'm getting air so I went to the spark I have replaced the distributor cap and rotor and ignition coil still the same thing what's the next step ?

Im having the same issue with my 89' 5.0 mustang. It turns but doesn't start and I don't think its getting fuel. There might be disconnected wire or relay. I know my 1997 f350 has a relay that won't let it start if it went out.
Im not sure if that helps.

try turning the key on, and check supply voltage to the TFI module on the distributor
not sure what pin it is off hand but its a white and light blue wire
did you check the power and fuel relay?
check fuses?
how do you know its getting fuel?

There is only two methods of trouble shooting...LOL...one method is patience the other is a Fat Wallet
the parts industry just loves the guys with fat wallets buying parts and repairing thru the process of elimination
Multi-meters are very cheap to buy...the sad thing of this method is you can replace the entire ignition/electronic system and still...."Crank..But no start" when after spending a thousand dollars....all along it was just a ****ty ground connection

Dillan,
Welcome to FTE. There are a few questions that can help us help you if you can take the time for us. There's plenty of knowledge here in the boards, just need to help get to the right questions.
That being said. Have you pulled codes yet. If not you can either do that with a code reader, or by counting the flashing light. Just search the forum for code reading on an OBD1 system. You'll find what it is. Then post the codes up EXACTLY as they come out. The numbers mean a lot to some of the guys here, and they can give you better direction from there.
Next step is to guarantee it's a spark issue. For that let's hear what the fuel pressure is at the rail. Just because there is fuel there, doesn't always mean it's got enough pressure to run. So, if you don't have a fuel pressure tester, you can usually rent one from the parts store.
Hope that helps.

I'd give you good odds that the ignition module on the side of the distributor went dead. Just too common on this vintage of vehicles with the module on the side of the distributor. I'd spray some starting fluid in the intake and if you don't get any response out of it.
You need a special tool to remove the ignition module. And you probably have to turn the distributor on a 5.0. Make some marks before you turn the distributor so you can get in close enough back in time to start it, so you can later fine tune it with a timing light.
