Suddenly the engine it will crank but not start up?

Wow! I'm impressed with the response--thank you. The information was excellent, but it applies to an OBD2 system. This, of course, is a 1994 truck; OBD1 --quite a bit different. Might you be able to send the same set for the 1994? Even the fuse box layouts are very different. It would be most appreciated since I don't even have an owner's manual. As soon as I can complete the Evap system repairs, I'll be ready to work on the no start problem.
Again---thank you so much for your willingness to help.

Masterwrench:
I should have said that a little differently: This situation began when I discovered there was a failure to hold pressure somewhere in the EVAP system---( It turned out to be a failed filler neck hose thanks to California continually reformulating the gas, disregarding rubber compatibility of fuel system parts.) Thanks EPA, thanks carburetor!
Draining the fuel tank was done in case it needed to come out for cleaning.
Up to that point, anytime the engine needed to be running for any reason it never failed to start the entire time it has lived here. When the no start happened, relays checked okay, but spark was a no show. That triggered my mayday.
There may be a clue, the jumper technique used to pump out the fuel didn't work as advertised with key on, fuel pump relay jumpered it would pump for 2-4 seconds then stop instead of continuing to run. Didn't seem right, so turned to good ole' siphon hose which did the job, but still no spark. So, that job's done. Everything seems okay. So, did I miss something? Did I burn something out? I have a feeling it'll be something really embarrassing! Hope not.

The Ranger will turn over and will start with starting fluid. But will only run with the starting fluid. There is fuel pressure at the test port. I have not gotten a fuel pressure gauge yet to see how much pressure.

Hello the fuel pump is working and the pressure is 40 psi. When I try to start the truck it almost gives you hope that it will start. But of course it does not unless I spray starting fluid in the throttle body. And it will only stay running as long as I keep spraying starting fluid. I looked at the fuel pressure regulator and pulled off the vacuumed line I did not see or smell any gas. I bought a new regulator anyway I think I am going to try that next. I will keep you posted.
Thank you, Ben

I just put all new gaskets on my motor and once back together. I am having crank no start. It was throwing trouble codes 114 and 116 so I replaced both the coolant temperature sensor and intake air temperature sensor after which it still shows those codes and also 513 now. I checked the wires to these sensors and I was showing over 6.3 volts. I also believe it is getting flooded when I attempt to start because I can smell gas pretty strongly and spark plugs are wet. I am not sure if I need a new PCM, ignition module, or if it’s a wiring problem. I got an engine wiring harness off another truck same model and year in hopes it is a wiring issue. But need some direction as it is my daily and got to get going. Thanks

Used it and parked in my driveway unloaded it and went to park in side drive and it didn't start. Just cranks over but no start. When to check on the spark but have tried so much the battery now is on the charger. So right now I can't check to see if it is getting spark, the plug looks good. I need help, can't get it to shop to get it fixed. It is on me to get it fixed.

Every now and then I can go to start it and it won’t start, just cranks and cranks, won’t start until I pop the hood and shake the fuse box and it starts. Could someone please help?

I have the truck listed above XLT model. I bought it a couple days ago and the guy said it would run sometimes and sometimes it does not want to start. I got it to start after a couple tries of cranking. Ran fine but had an idle that seemed to have a misfire but ran great driving. I let it sit overnight and it did the same thing. I hooked a battery charger to it cause battery was getting low. After a little while it fired up and idled but still had that misfire like idle. The rpm's bounce from 900 to 1,000. Engine light is on so I attempted to read the codes with a $6,800.00 Snap On scanner and got a communication error. The plugs and coil are new. I also checked the ECC fuses and they are all good. Anyone have any idea?

This is a 1993 ford ranger. 180,000 miles. It normally starts ok. Occasionally it will turn over but won't start. If you keep turning it ever min or so for a few seconds, it will start after about 20 min.? I have had the starter replaced. No error codes show on the computer. Happens occasionally when engine is cold or warm. What do I look at next?
