Try checking and making sure you are getting fuel to the fuel rail there should be a serator valve on the line on the engine. If you are not getting fuel to it make sure the fuel pump fuse and relay are in good working order. Check and see if you can hear the fuel pump running. If you are not getting fuel to the rails and can not hear the pump running the pump is possibly bad.

    No you should not have. There should not be any kind of anti theft device that I know of connected to this part of the harness.

    On a '94, there isn't a stock antitheft. That pack rat had more to do with it. Just replace the fuel pump wiring and you should be good to go.

Why will not the fuel injectors open on a 2002 Saturn l-100? The fuel rail has correct fuel pressure. The injectors will open when I give them a 12 volt supply in my shop.


AT THE INJECTOR CONECTOR YOU NEED 12 VOLTS KEY ON AND THE OTHER IS THE NEGATIVE PULSE SIGNAL CAME FROM ECU BUT YOU ALSO HAVE A CRANKSHAFT POSITION SENSOR AND CAMSHAFT POSITION SENSOR MAY BE BAD

94 Opel kadett 1.6 single injector. Petrol does not seem to get thru for car to start.petrol pump is ok.where could the problem be.


Check the injector circuit. Here's how injectors usually work: when key is on, they have live power available to them. Key on, the circuit is turned on, so power passes through a fuse to the injector on the power wire. (Check the fuse- it's under the hood, most likely.)
To make the injector "pulse" or spray fuel out, the engine computer will internally ground the circuit for a split second. The injector has a power wire to it from that fuse. Then the ground wire at the injector goes into the computer.

If you have a test light, you can test the circuit. First, clip a test light ground lead to negative battery post. With key on, and the injector connector unplugged, check for battery voltage on the power wire. One of the wires should have voltage and will light up the test light. Now, move your test light lead to the battery POSITIVE post. Have a helper be cranking the engine over while you probe the ground wire-the one that did not light up the test light. If the injector circuit ground is good, the test light will now be blinking. (You are putting voltage into the ground wire to the computer, to check if it is properly grounding the circuit. Every time the light blinks, the computer has grounded the circuit.)
If the circuit passes both tests (key on, steady test light on power wire; engine cranking, blinking light on ground wire), then the injector circuit is good. The injector should be pulsing when it is connected and the engine is cranking. If no gas is coming out of the injector, could be that fuel is blocked somewhere (filter?) from reaching the injector, or it could be a shorted injector. Someone with a volt-ohm meter should check the resistance across the injector terminals and compare with manufacturers' specifications. This will determine if the injector is bad.

Engine only firing on left bank rtf. Side no. Fire will start and idle


Check for spark on the side not firing. If there is spark, the injectors on the right side may have a problem in the wiring to them. Older multi port injection systems used a "bank fired" approach: all the injector grounds on one bank splice together before they go into the computer to be pulsed.
All of the injectors have a steady voltage applied to them when the key is on. The same color wire to all injectors is the power wire, it is a fused circuit, the fuse is in the power distribution box, and is hot in run or start. When the computer internally grounds the injectors, pulse occurs and fuel is sprayed out. Check if the right side has power to the injectors with key on, use a voltmeter or test light. To test an injector circuit, purchase a cheap "noid light" from a parts store. You plug it into an injector connector, then crank the engine over. If the noid light is blinking, the power and ground circuit is good for that injector.

Truck won't start


If the engine will not crank, it could be the starter, the neutral safety switch, or a bad connection.
A mechanic would check the starter circuit back to the key switch.

96 Lumina 3.1 won't start. It runs when I spray starting fluid in the throttle body. It has 42psi fuel pressure at the fuel rail. Is it bad injectors?


It is not bad injectors, it is lack of injector electrical pulse, never would all the injectors fail at once. See if you have 12 volts (use a 12 volt probing test light, avail at any auto parts store for less than $5) to one wire of the two wire connector of each injector with the ignition key in run position. If the test shows no hot wire at the injector connectors then check fuses marked ECM1 and ECM2 in the under-hood fuse block. If they are popped then you have a shorted harness or component.

My 94 ford explorer 4.0 cranks but wont start. i have 38lbs of fuel at rail port and spark at wire. it also runs on etherfor a hot second. what else can i try?


Check your injector circuit. It will also let you know if the PCM is allowing the injectors to energize. Here's how:
Pull off one injector connector. Turn key to on. Use a test light and clip the black lead of tester to ground, Use the tester's probe to probe both wires in the injector connector. One of the wires should have power and light the testlight, meaning the injector power circuit is working. Now for the injector ground circuit.
Move the black lead of testlight to the battery positive post. Now probe the wire in the connector that did not light up. Have someone crank the car over. When cranking the test light SHOULD be blinking, meaning the PCM is properly grounding the injectors to work. If both wires passed the test, your injector circuit is good.
If it's not working,either the power circuit from ignition switch to injectors is out (no steady light), or the ground circuit from injectors to PCM is not working (no blinking light).
Good luck, post back with results for further assistance.

Buick lesabre 94,crank but wont start,got spark but not open fuel injectors


Check your fuses. Check at an injector plug for power with the key on. One wire would be power with the key on. The other wire would be a ground pulse when the engine is turning (running or starting). Both wires may show hot but it could just be power feeding back. If you have a test light capable of testing for ground, check for ground as well while the engine is cranking (a noid light is ideal).
If no ground or you cannot test for it, take the ignition module to an autozone so they can test it for free.

I need a wiring diagram for a Merc Sprinter 311 LWB, 2004.. Now doesn't start after a so called Merc Mechanic took the engine out and rebuilt it... Sounds like a fuel injector problem, maybe with the...


I am going to give you some generic advice that works on all makes and models. First check the fuses, Pull them as they can loose contact, thus loose power. Check all the igntion, ECM/PCM and BCM, Fuel pump and relay, and injectors fuses. Best to check them all, but atleast these. Also check to see if there is a security issue, your manual should tell you how to reset it. Check the fuel pressure, just because you have fuel, doesn't mean you have enough pressure. Wiring harnesses are what I call idiot proof, You can not plug the wrong wire into the wrong part. Engineers got something right. Now if all that checks out then you need to work your way to the injector harness. Disconnect a few that are easy to access. First turn the key on and check for power, one wire will have 12 volts, the other wire goes to the ecm. A test light or volt meter will work. If you have power then you need to test the ecm, you can use a volt meter or there is a NOID test light you can get that is inexpensive at the parts store. using the meter put the leads to the harness leads and have someone crank the engine over, the meter should jump in voltage, it wont read 12 volts as it is on for milliseconds. if you use the noid light it will blink. Check several injector plugs.
When you get this far, Let me know as I have lots more. I don't want overload you to much.

1993 chevrolet silverado 1500 will not start has new filter and pump can spray fuel in to it will start then dies when it runs out of the fuel sprayed it it


It sounds like your injectors are not firing which could be a crank signal problem or wiring,distributor pickup coil problem or a computer problem.One wire to your injector should be pink this is the power wire it should have around 11.5-12 volts with the key on. The other wire is ground that the computer uses to fire the injector which you can check with a good test light hooked to voltage. and work back from that point if you have neither at the injector.
