Fuel injectors not getting signal to open

I have tried a lot of things to fix this problem but no luck. I need to see if there is a link between the injector and ECU so that i know what is causing the problem. I don't believe it is the ECu because everything else is still working (i.e. air, spark and all other electronics)

    yeah i did check it may be that the camshaft positioning sensor may be out. It controls the fuel while the crank controls the spark. I didn't know that until just now. We tested the injectors and the open and close just has no signal going to them

My 1993 Dodge Dakota 3.9l v6 4x4 magnum wont fire it will crank over but no fire? The fuel pump relay, crank shaft sensor , spark plugs and wires were replaced. I don’t know a lot about this no fireing...

check the compresion in all cylinders 100 psi (compression good) check the spark -check the fuel pressure.30 psi at gauge with switch on.(if no keep pressure with switch off injectors or fuel pressure regulator are bad
check the signal to the injectors (get little injectors tester at autoparts) if no signal check the ground to the injectors black wire
or the other wire (computer)= good signal to injectors and good fuel pressure and good spark (defective injectors)

Did a tune up on my 91 dakota, but still burning lots of gas. change wires, sparkplugs, cap, rotor, and oxygensensor but still burning gas out the tail pipe

Try running fuel injector cleaner through the gas tank. A fuel injector might be stuck open, letting lots of fuel into the engine. Also try replacing your fuel pressure regulator, and inspect the fuel tank return lines.
Good luck

Where is the fuel injector located and how hard to replace. 2002 cadillac Deville.

It's not that difficult to replace. You should be able to get any diagram you'll need, as well as a lot more useful information by registering for free at Registration gives you free access to repair manuals and some shop manuals, most with sections that can be downloaded and printed.

Got 93 blazer wont start fuel injected if you primer first it starts then dies out all sensers fuel pump injectors turantula eeverythings been changed all most fuel goes to turantula but wont go through...

Try changing out the crank position sensor if this sensor is bad it doesnt send the signal to the computer telling it you are trying to start the engine and the computer controls fuel flow at the injectors if it doesnt recieve this signal from the crank position sensor you will never get it started good luck and let me know if this fixed your problem thanks.

Fuel system not getting gas correctly

Make sure that there is signal at individual injector. The injector needs to have a signal so it can open the valve to shoot fuel in each cylinder. You can buy the NOID to hook up at each injector. When cranking the engine, these NOIDs will light up sequentially then you have signal. Next thing is to check if you have enough fuel pressure in the line. If it is not then check the fuel rate( the amount of gas delivered by the fuel pump by minute). It the fuel pump rate is meeting the spec then change the fuel pump regulator, If the fuel pump rate is not meeting the spec then change the fuel filter. Repeat the check to see if there is an improvement in the fuel pressure. If it doesn't improve then change the fuel pump. This is the logic of troubleshooting. However, considering the time and labor hours when doing DIY, I just replace everything since the parts are not costing more than the time spending in taking the parts in and out. Good luck.

1997 grand cherokee getting fuel to fuel rail but will not start

Could be a number of things ...I'd check the ASD relay first. If the asd does not see a signal from the computer it won't open the needs to see a signal from the crank position sensor or it won't send that signal.
You can find good test procedures in haynes manual and better wiring diagrams in chiltons. You will also need a good multi-meter to do the testing If you don't find the problem right away, take notes during tests. That will help you avoid testing twice and also can build a "picture" of what is going on as items in your notes will begin to show a common problem that may seem like nothing when taken at face value.
Tests take time and patience....Good luck.
Any questions about your findings? just ask and someone will try to help!

No fuel to injectors....

Your injectors are controlled by electrical pulse. Even having fuel pumping to the injectors, if they are not opened, fuel is not sprayed into the cylinders for combustion.
You can find NOID at any auto part store to hook up to the connectors of the plug going into the Injector plugs ( like attache image) to check if there is signal from Injector module control or not.

1-When you crank the engine, the NOID will flash indicating you have signal, but your injector is bad. This is a problem.Need to check every one.
2- If NOID is not flashing then you don't have signal from Injector Control module. This is a problem. Good luck in finding.4b5c5a7.jpg

Fuel injectors won't open

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.

Fuel System on 1998 GMC Jimmy 4.6L engine

That's right! Fuel pump is in the fuel tank, some car has opening to acces in the trunk under the carpet, some car you need to take down the tank, my advise is get your self a service manual for your truck its about $25.00 and it will help a lot.
Good luck.
