Did you check the fuel filter?
or possably the catalitic converter is cloged, check the exhaust pressure.

SOURCE: My 1994 suburban engine stops. No fuel, no MIL light.

I checked all of the fuseable links and they were all good. Next I decided to check all the power wires to the ECM and also the grounds from a wiring diagram because the Mil is controlled by the ecm and the bulb was good. The ecm is located behind the glove box. Bingo, the orange wire was only reading 3-5 volts at the ECM, but 12.5 volts after the fuseable link at the underhood fuse block (passenger side firewall). I ran a temp wire directly from after the fuseable link to the orange wire at the ecm and the ecm turned back on and the Mil or "check engine soon" light came on too. The truck started up and has never run smoother.

Note that at first the truck just stalled out and I could restart it right away with no error codes. Eventually the stalling became more frequent with longer reset times required. Once it threw a "code 54" and I thought it was fuel related as each time the gas stopped and I could still start the truck with gas poured into the TB. Ignition ok. My fuel pump turned on and ran if I tested it. I even checked the pressure regulator and the fuel filter to no avail.The orange wire that powers up the ecm is technically part or the fuel pump relay circuit as it also feeds the fuel pump relay 12.5 volts all the time. The thin orange wire from the fuse block is joined to two other thin orange wires in the large group of wires that heads to the ecm along the firewall behind the engine. I had to dig it out of the many wires to find it and remove a lot of tape. It is amazing to me that this one little orange wire could cause so much grief and be so hard to track down. I could not have afforded to take this problem to the Dealer.

You have a short (bear wire) somewhere. Trace the wire and find it.

By running the car out of fuel you may have damaged the fuel pump. You need to perform a fuel pressure test with a pressure gauge to see if the fuel pump is working and is working at the proper pressure. You might check your fuel filter as well. I suspect a bad fuel pump.

Could have been an air lock that worked its way out. Did you add any coolant prior to driving? Keep an eye on it, another thought could be your thermostat stuck closed and then opened. Is it normal to run at 200? or 160? Perhaps the weather was extreme which might cause the sudden drop.

Recently I left my truck without driving it. It


Yes, It sounds like the Gas junk in it and has clogged up the lines.
Italso could have electrical difficulties.
As the seasons have changed and gotten colder this effects all things electrical and mechanical.
Also, it could be both, check your fuse block for blown fuses and also check all your fluids.
Take it to be looked at and tested by a trusted mechanic shop so they can diagnose the problem more closely!

try to put 2 gal of gas.
if you run out of gas, the system require little more than a gal of gas to get from the pump in the tank through the filter to the injector. Approximately 1gal just to pressured the fuel rail.
