Wow! an '82. Nifty. Yes, it could be a grounding problem. The older systems used injectors that draw a lot of current. Especially check grounding between the fuel 'computer' box and the engine. Physically/visually check terminals or use a light bulb tester. A volt-ohmmeter is not reliable when checking high current circuits because it doesn't demand high current flow.

I saw the exact type of thing on an older BMW not long ago.

This is a common problem first try carefully remove the retainer clip wire that holds the plug on use a volt ohm meter plug them in plug set for 12v dc turn engine over to see if your getting pulse from ecu if not check fuel injection relay check all your your relays try using dielectric grease and lightly coat all pins push up and down to allow good contact with all pins if you are getting good signal bad injectors

Changed the fuel pump and filter...still won't start


Check the injector circuit. There should be a fuse for the injectors. Each injector has a power wire and a ground wire. The power wire should show current when key is on.
Your fuel pressure should show around 50 psi with key on. Is it?
How to check the injector ground circuit: Use a test light. Clip the lead of the test light to the positive battery post, and use the probe into the ground terminal of an injector connector (the connector is unplugged). Now observe the test light while someone cranks the car. If injector ground circuit is working right, the test light will be blinking-meaning the computer is correctly grounding the injector circuit for a split-second each time the light blinks. If no light, check ground wire from injector to computer. If light does not blink but is steady, computer failure.

Why do i get a contant ground at the fuel injectors wire


Do you have this problem on all injectors, or just one?
The ground alone could not open the injector, you need a positive too

The injector needs one side power and the other is control,or a ground the main sensor resposible for injector on time is the cam position sensor.3_18_2012_2_04_02_am.jpg

Fuel injector fuse is blown, keeps blowing. Engine turns but won't catch and start.


if the injector fuse is blown then the car won`t start as its not getting fuel into the motor to fire.if the fuse keeps blowing then you could have an injector/s that is drawing too much or the injector driver in the ecm may not be any good and needs replacing or a used ecm.it could be a short some where in the wiring for the injector system that is going to ground.

Blazer 1999 won't start got spark new fuel pump


Pull off one injector connector and use a test light or voltmeter to see if one wire has power with key on.
Power to the injectors is fed through the ignition switch, so with key on, you should have power there. The injector ground is inside the ECM. If you have power, you'll have to diagnose the circuit for why computer doesn't ground the circuit when it should.

1999 2door blazer installed new fuel pump 60psi when tested won't start dump gas in intake starts and shuts off ??????


Sounds like your injectors aren't opening if it holds that pressure. Get a "noid light" at parts store that fits your injector harness connection (just a few bucks). Just pull connector off injector and plug in noid light. When you crank engine, the light should blink rapidly. Try all of them, or at least one on each bank (side).
If light doesn't blink, then check your injector electrical circuit. Power to them is fed through your ignition switch, and the ecm grounds that particular injector at proper time to make injector work.

1989 K1500 was running fine and just quit. Not getting gas but I can hear the fuel pump start when I turn the key on. took fuel line off of TBI and seem to have plenty of gas flow but nothing comes out of...


you need to have the fuel pressure checked with a gage and volume as if its not at the spec the injectors won`t open to spray enough fuel.also you should check the injectors for proper voltages and ground as if these are not within specs then the injectors won`t work either

1992 chevy s10 2.8l v6 tbi 2wd 5-speed. no signal on the noid light tried a new computer, new distributor, fuel pump and relay, fuses, can it be a sensor? or oil pressure switch? oxygen sensor?...


i assume your talking noid light for the injector.have you checked for battery voltage at the injector and for the ground side of the circuit at the injector as either one missing it won`t work.the injector is grounded by the computer and the power is supplied when the key is turned on.these are the two places to start to check.

Fuel injectors wont open malibu 2004 clasic


Hello! Please tell me what you meant by "We took the wires to check for mass"?

However, you are correct, it is fuse #5 10amp. It is located in the under hood fuse block. Change the fuse; If it does not hold perform the following test...

With key off...Disconnect the Injector's plug in connectors...Each connector has two wires marked A and B...A goes to battery feed and B to the Power Train Control Module (PCM)...

Using an ohm meter set on the X10 scale measure from each plugs pin A to ground...It must be open, no needle deflection...If you read any resistance at all, the hot lead which is common to all injectors, is grounded in the harness...

Next measure from each injector (both pins) to ground...You should read zero ohms,,,No resistance to ground...If any one injector reads to ground it is defective...Replace...Since all injectors are tied to common battery, any one injector shorted to ground will short all of them to ground...
