Help!

'93 Wrangler 2.5L, 4 cyl, manual trans - Here's the problem: it won't start! Seriously, it acts as if the engine is not getting gas. It started out as a "hit and miss", sometimes it would start and sometimes it wouldn't. I took it to a mech who said it was the CPU. He ordered and replaced it. I drove it home and had the same issue. I took it back to the mech who "check everything" and could not find a problem. I specifically asked about the fuel system (lines, filter, pump). He said they were all good. It finally stopped running for good.

I replaced the plugs, plug wires, and distributor; checked the ignition coil; then replaced the fuel filter and fuel pump. Still won't start (does turn over though). When I pour fuel directly in, it will fire, sputter, then die. It seems as if it is just not getting fuel to the engine. Any ideas where I should check next?

Thanks

You need to check for fuel pressure and if you getting power to the injectors if you get power then your injectors are clogged or bad check all fuses and relays

My 94 did the same thing, I replaced all kinds of stuff. Then got word from another forum about a relay C104, mounted on the firewall next to the battery. I opened it up and cleaned it with electronic cleaner and hooked it back up. It corrected my problem and I have not had the no start blues since.
