Question about 1994 Chevrolet Lumina APV

1 Answer

Injectors aren't working on this van. Why is this? I know for a fact that the injectors are the prob... what would keep them all from working? I have replaced the fuel pump, fuel filter, camshaft sensor, spark plugs, and had the injectors themselves cleaned and rebuilt. The wires that run to the injects are hot when I test them with the ignition switch turned on. Could this be a bad crankshaft sensor? Or are the injectors bad? (They are way to expensive for me to just run out and buy without worries) Any help will be greatly appreciated.

Have you checked them for signal from the ecm, for that you will need a noid light, there will be juice going to the injectors and are activated by ground to the ecm, if you are not getting spark the injectors won.t cycle, good luck

2002 ford taurus,injectors work properly but gas goes by one injector into cylinder


When you say ,,, gas goes by one injector..... this means to me that a cylinder is getting flooded with gas. If this is true.... and you know for a fact that the injectors is good.... the problem has to be electrical. The injectors have power all the time and the PCM grounds the injectors to turn them on. If in fact the injectors are good and gas is still getting into the cylinder then there can only be 2 things that cause this... one... the PCM is defective and keeping the injector on ..on that cylinder... or two... the ground wire to the injector is shorted to ground somewhere. These are the only two things that will cause the injector to stay on. Be sure the injector is good !!

Ive got a 1985 toyota camry and it wont start, carb. cleaner will get it running 4 a little while,no gas getting to injectors. good fuel pump had it tested efi fuse i cant find. ??? can anyone help t


Try the fuel pump relay, and if you know for a fact that you fuel pump is functioning ok replace the fuel filter seeing there is no gas going to the injectors. Other that that I think it might be you fuel pump.

I NEED TO BLEED THE FULL SYSTEM ON RENAULD KANGOO 0/2 PLATE 1.9 DIESEL VAN


Crack open no 1 injector while a friend turns over engine and it should fire up although I would have thought it would self bleed as I know for a fact that a Ford Escort would have otherwise you may have a leak in the fuel system

How do i bleed the fuel injectors?


You don't ! Injectors do not require bleeding. Fuel under pressure surrounds the inlet of the injectors, and when the pintle is raised by an electrical pulse, fuel sprays out the injectors outlet port at the bottom. No bleeding is possible nor required.
If the injectors aren't working, the electrical circuit has a malfunction, or the fuel pressure may be too low.

I have an esteem 1999 2 injectors aren't getting electricity from the ecu spark plugs are all hot w 3-4 inj. working properly but why would this happen


Don't know. Either a malfunction internally in the ecu, or bad wires from ecu to injectors. You could pull off the ecu connector and check for continuity on the wires from ecu to the two injectors. If the power.wires are not broken and show low resistance, check both ground wires from the two injectors to ecu for continuity. If the wires are good, it must be the ecu.

What powers the fuel injectors on this van? Is the fuel forced through the injector by the compression of the fuel pump, or the suction of the vacuum compressor? Or is the injector given an electric signal...


THE FUEL IS PRESSURIZED BY A FUEL PUMP INSIDE THE FUEL TANK, THE INJECTORS ARE OPENED AND CLOSED ELECTRICALLY BY THE FUEL INJECTION COMPUTER KNOWN AS THE ECM, THE COMPTER/ECM RECIEVES INFORMATION ON WHEN TO INJECT FUEL AND FIRE THE SPARK PLUGS FROM THE CRANKSHAFT AND CAMSHAFT POSITION SENSORS, HOPE THIS HELPS

I have a 93 Chevy G20 VAN G20 with a 4.3L engine that has TBI my van starts and runs for a few days. Then it will not start after sitting for a day or two it starts again and runs fine. What could be the...


There are three relays all grouped together on the firewall on the passengers side. All three are related to your situated. We can eliminate one of them because you stated that the fuel pump is operating fine. Now that leaves the relay for the ECM(engine control module) this tells the injectors, cold start and run, when and how much fuel to supply and also controls ignition timing and spark advance. The third controls the AC compressor. Now I've got to remind you that I started working on fuel injection systems the day they started failing here in the US around 1972.These were such vehicles as Mercedes, Saab and Volvo. I've worked on every configuration, TBI, MPI, diesel etc.etc. I may on occasion cross one fact with another or mispronounce certain aspect of a system however, These three injectors are where you want to concentrate your efforts. With some finnesse you can swap the harnesses from one to another. If your car runs fine and your AC suddenly does not, then you know that that relay is faulty. Do this until you get your answer. Best of luck my friend, Dana
