I have a 95 Ford Ranger, 3.0 with 74,000 miles. About 50% of the times it won't start, as if I'm out of gas. I changed the fuel pump and filter, three O2 sensors and Camshaft Position sensor. I can try for 10 mins without it starting and then come back an hour later and it'll start right up.
Please help

The camshaft gives the computer the firing order-The crankshaft position sensor identifies the position of the piston and engine speed it inputs this signals to the computer then Comp. Turns around and activates its driver circuit to fire the coils

Check the CPS

I changed the Crank Position Sensor and about 50% of the time it will crank but won't start. I did notice when the key is in the on position I get all the accessories, but I dont hear the relays clicking or the fuel pump coming on. When that happens, I can crank it but I dont get any spark. Most of the time when the key is in the on position, I hear the relay, fuel pump and than relay. After that if I try to crank the engine, it'll start.
Please help.

Turn key to On and look for power at the coil positive do you have power? Also did you hear the fuel pump?

It sounds like the ignition switch is failing the way you describe it. Or a loose connections from the battery to the ignition switch.

I had a dead sensor (differential pressure for EGR flow) and when I replaced it I could at least reliably start the truck. Other problems still exist and it runs rough or the power fades under acceleration/load sometimes (most times).
