Question about 1999 Chevrolet S-10 Pickup

1 Answer

Truck will crank but not start

I replaced the fuel pump, filter, and checked all the relays and fuses. I took the fuel line off where it goes into the throtle body and turned the key over and it is pumping fuel, but when I open the the top of the throtle body there is no fuel in it. I can take gas and pour it right into the throtle body and it will run until the gas burns up and then it will quit. I can see a pressure sensor on the side of the throtle body and there is also a " black thing " on the rear with a bunch of wires that goes into it. Could any of those two be bad ? Please help me.

Try checking all the fuses with a test light may be a blown injector fuse.

2003 chevy silverado 5.3 will crank but not start and has no power to the pcm1 fuse


What make vehicle ? You need to find a power distribution chart an see where that fuse gets it power . Some vehicles have a relay that powers up the vehicle . ford has power hold relay , gm on some models has a run / crank relay , Chrysler has ASD - auto shut down relay , Asian vehicles have a main relay etc... But as long as there is no power to the PCM it's not going to start !

I cant get my a985 F250 to stay running, bought a new Carb, bought a new ignition control module, new coil


Check the wiring from the ignition switch . When you got fuel as the engine was cranking then the power for the pump is on the start side of the ignition switch and not in conjunction with the run side of the switch.. IT could be a fuse in the run circuit or a faulty pump relay.

I replaced the turn signal switch and now it wont start. i can hear the fuel pump kick on. makes no sense


You said you hear the pump come on, then said fuel pump not running ???
Check the fuse for the pump, preferably with a test light to verify power is there. Key must be in on position. If the fuse is powered, feel for the fuel pump relay to click when you turn key to on. Put your finger on it while someone turns key to on. If it clicks, check for power at the tank connector on the pump wire, while the engine is cranked. If power there when cranking, the pump must have failed and needs replacing. If the relay clicked with key on, and no power at the pump wire at tank while cranking, then check wiring from relay to pump connector-the fuel wire may have broken.
If the relay doesn't click when key turned on, check for the power feed for the pump at the relay terminal. If the relay has power available to be transmitted to pump, then the relay's signal from the computer or the ground side of the relay's coil signal (from the computer) may need checked.
If the pump is working, and you have good pressure in the lines, check the injector circuit. Also a fused circuit, so check the fuse first. The injector should have a steady voltage signal to it with key on. The injector only has two wires, the power wire and the ground wire which goes to the computer. When the computer momentarily grounds the injector circuit, the injector "pulses", causing fuel to spray out the bottom.

No fuel up to injecter pump truck just stalled


Did you check for fuel pressure on the line from the tank while you had the filter off? Do you hear your fuel pump prime when you turn the ignition on? First I would listen for the hum of the fuel pump when you turn the key to the run position (not starting the engine) May have to get a helper and listen at the gas filler neck with the cap off. If you dont hear your fuel pump, check your fuses and relays. If the relay clicks when your helper turns the key on ( put your finger on the relay and ear down close to feel/hear the relay actuate)., and fuse is good, yet you do not hear the pump prime, I would say your fuel pump is shot.

If it is a diesel,check for fuel pressure coming off the direct drive pump hose while cranking the motor.

Have no power to the fuel pump. Truck will not start. what to do next?


1. make sure you really have no fuel delivery. open a line convenient for you as in cold start injector or fuel filter, disconnect ignition coil lead and crank away a bit to make sure you're not getting fuel.
2. I assume you're getting spark.
3. check efi fuse in main relay box passenger side inside right fender. if good check that you have juice at the Co relay hidden in the passenger kick plate. its the white-red terminalwhich delivers the current. the Circuit opening relay is really the main enchilada for getting the pump up and adam.
4. still no go. you have to address the Co relay itself. test terminals with ohm tester. also you can jump wire the Bp fP terminals in the diagnostic connector on the side of the main relay and see if the pump goes.
5. and lastly it might be the pump itself

1985 Ford F-150 Truck (EFI) Fuel Problems


Same problem with my 85 F-150 5.0 EFI---turned out that the fuel pump relay under the hood was teriffically corroded on the inside (I opened up the relay to look inside). When I checked the voltage at the fuel pump it would show 3.5-6 volts instead of 12 volts.

I was thinking fuel blockage or perhaps failure of the in-tank pumps. Sometimes the truck would start and run, othertimes it would neither start nor run. Typically, if running it would stay running until turned off (where the relay had to break).

Changing the green fuel pump relay fixed the problem--12 volts now at the pump and no reoccurance.

Good luck--let me know if this fixed your F-150.
