1994 Jeep Wrangler Question: Cranks won't start
My 1994 Jeep Wrangler 4.0 will run fine then all of a sudden will crank but won't start. After a day it would start back up with no problem and last for a few weeks then do it again. I have replaced the distributor, coil, wires, and spark plugs. Now it is to the point when it happens it won't start for 2 days. I'm not sure which sensor module or computer to replace next without replacing them all. Please contact me at firstname.lastname@example.org. - JPochron
Did you ever get a fuel pressure check to see if the fuel pump works? Can you hear the fuel pump buzzing with the ignition ON? The best thing would be to get a diagnostic from a Jeep specialty shop, this way you don't have to replacing good components. Zee - ZeeTech
Fixing cars starts with diagnosis and ends with replacing or repairing things. The idea that you replace parts until it's fixed without diagnosing the systems first is not going to make a successful career if you're a mechanic. You need to check for spark, fuel pressure and injector pulse when it's failing. Once you have the failure identified, you can diagnose ignition, fuel pressure or whatever you've found.

Started one day, wouldn't start the next. Had this problem before, so I replaced the fuel pump. Cleaned the fuel tank while it was out. Still won't start. Fuel pressure good at pressure bleed valve.
