Put at least 5 gallon of fuel in the tank. Charge the battery full with a battery charger. Turn on the ignition without starting the engine. See if you hear the pump run for a few seconds and then shut off. You may have to listen carefully in the truck to hear it. If you hear the pump it is more than likely ok. Do this about 5 times to prime the pump. Purchase a can of starter fluid and follow the directions on the can to start the engine. You may have to do this time and time again until you get fuel to the fuel rail. I would then replace the fuel filter.

First check your fuel system. If the fuel pump is bad you wont have any gas at the carburetor or the fuel rail if it is fuel injected. Relieve fuel pressure, find the fuel line and disconnect it. Crank the engine a couple of times and have someone watch for fuel coming out of the hose

1.6L or 1.8L vastly different engines... and EFI.
fuel to the rail , only means the pump is active , never good.
28PSI is minimum on all cars. 1psi will never start a car. ever
and the rail will shoot fuel, all day. it fruitless , unless the rail is dead.
see?
First the laws of EFI. (works all gas EFI)
  1. all fuses good.
  2. 12vdc to EFI system , below 10v is bad. (see lamps dim? bingo)
  3. The PCM (EFI brain) will never inject if it sees CMP/CKP or spark primary dead. ever. so, spark is first.
that is double reasons, fuel cant burn if no spark and if ECU
thinks spark is bad it cuts fuel, (fire safety and fuel hydralocking reasons)

so you connect any scan tool to the DLC, OBD2 port , by knees.
and crank for 5 seconds, release key, no turn off
see DTCs (errors) for CMP, or CKP sensors (cam/crank?)
bingo
no, then you crank and look at the RPM PID , live data stream the scan tool, see RPM go to 250rpm cranking, good.
ok , PCM thinks all is good....

i then check the #1 injector with a NOID lamp
i crank it flashes, good.
if not , i do all injectors , if one fails the pcm is dead on this line.
if yes, all dont flash the PCM is seeing some gross errors. ask. why./?
if all flash, then the fuel rail is dead. and your rail test was useless.

until you discloses engine option (size) I cant give spec numbers.
i then connect my fuel pressure gauge $20 tool to the fuel rail test
port, and i get 10psi, FAIL
i check voltage to the fuel pump cranking, i get 8v, bingo bad wiring
or bad fuel pump relay.
say 10psi and 12v at pump cranking,
the pump is bad, or the filter clogged , or the fuel pressure regulator
is stuck wide open killing all legit pressure.

that is how i do it.
keep in mind the PCM cant see fuel pressure on most cars.
some newer cars have this sensors. (nice)
low fuel pressure,. renders the whole EFI , useless. just junk.

98 Deville had a dead batt. Replaced, turns over but wont start


Sounds like fuel issue, remove the black plastic cadillac cover on the top of the engine, then find the fuel rail on top, and remove the black tire cap looking thing on the end of the fuel rail. Now you will have to get a fuel pressure guage ($45), and screw it on right there. Or you can also just poke that little valve with a ink pen to see if any fuel squirts out, it should come out with alot of force, it is like a valve on a bicycle, it only lets fuel out when you push on the valve ***. As for the battery being dead perhaps you left your parking lights on? My 97 deville, had a cold start problem, that it took 5 minutes of cranking off and on, to get it cold started, but after it was running it would start throughout the day just fine. I ended up replacing the fuel pump in the tank, and the fuel filter on the rail.

My wife ran car out of gas and then ran battery dead trying to start it. Now car will turn over but wont catch and start. Any ideas what the problem is?


The fuel pump is cooled by the very fuel it pumps. Without fuel to keep it cool it can simply burn out; especially if it has been running during a lengthy attempt to restart. Pump function can be tested by loosening the Shrader (car tire type valve) valve fuel rail on the engine whilst the pump is running and seeing the fuel squirt out. If no fuel squirts then replace the pump.

Ran out of gas and mow it wont start


You will want to get a fuel pressure tester and test pressure at the fuel rail on the engine. If you have low or no pressure there is a good chance that the fuel pump is dead. Running a fuel pump dry will cause it to overheat and burn out.

Car wont start


THere is no gas in the fuel rail at the time gas is running out. WHen you fill the tank, it needs to pump for a while so fuel can fill up the rail then the Fuel distributor so it can build up pressure for the injectors to work properly. It need to continue cranking at least 2 minutes. However you don't want to run out the battery, so can just turn on the key to hear the sound of the fuel pump stops, then turn key off turn key on again. Repeat this for 6 times then start the engine. The reason for it is that every time the key is on it turns on the fuel pump to prime the line then turns pump off after a specific time, then it turns on again only when key is at ignition position. By doing this you help to pump gas into the fuel rail instead of the starter continue cranking draining down battery fast. Cheers.
