88 f150 302 no spark or injection.
-turns over
-battery is good
-Relays are only 3 months old
-ignition coil works
-ecm works
-spark plugs are good
-fuel injectors are good
I think it's a wiring problem but I have already looked at all of the wires and connections. Any ideas on what to check out?

If you are getting power up to the coil through one of the little wires that hooks onto the coil, with the ignition switch turned on, I would give you good odds that the ignition module on the side of the distributor has gone dead.
You will need a special tool to remove and reinstall the ignition module. Also on a 302 you will probably have to rotate the distributor to get at the bolts holding the ignition module on. Make some marks before you loosen the hold down bolt so you can get the distributor close tom back in time.

I agree with 88xlt. It sounds like you have a bad ignition module or stator/PIP (Profile ignition pickup) sensor. The stator provides engine RPM, cylinder identification and cam/crank position. The signal passes through the ignition module to the PCM, so it would be a good idea to replace the distributor with a reman which comes with the stator and ignition module.

Most rebuilts have PIP sensors that will run a while then stall and restart after sitting a while.
If you choose a replacement distributor get a NEW aftermarket distributor. Just make sure it has the same material(cast or steel) as your old distributor.

Yes, go with a new one. Make sure that you get the one with the cast gear (for hyd flat tappet cam). The steel gear is for a hyd roller cam which ford introduced in '93 model year.
