Power to the injectors means little if there is no pulse to activate the injectors. That comes from the ECM and the voltage of the pulse is controlled by the accelerator position sensor. Secondly if the injectors tips are blocked then there will be nothing squirting out when required.. So remove an injectors and have they checked out professionally. run the fault codes to check for faulty sensors that control the injector action..

check wires at throttle body. can use a 12 volt test light to check for current. if you have spark it is not the ign module. set meter for 12-20volts. should have 2 fuse boxes on this model, one behind right side of dash at floorboard

SOURCE: 90 k1500 tbi no fuel from injectors

from the sounds of it its going to be one of 3 things 1) the injector is bad or 2) there is no power getting to the injector 3) bad relay switch.

1) to find out if the injector is good. pull the injector out and with some wire ground one side and touch the other side to your battery, every time you tap the wire to the bat you should here the injector click..

2) if injector is good get a test light and test to see if power is coming out of the wires that go to injector( on some vehicles you have to have the motor turning over befor power is sent through wire, so have someone turn the key while you check the wires with test light)

SOURCE: 1997 Dodge Intrepid cranks over won't fire

I have this same NO START problem...
Began with tach giving readings not exceding 1200 rpm with strange 4000 + spikes.. Cruse control would not turn on or off at times and indicator light would only work sometimes..Had several episodes of excessive cranking to get it to start.. Stalling out while driving and even at freeway speeds.. Pulling the negative cable for 10 min. allowed it to start although with lots of cranking and put it in limp mode which required another computer reset to get out of.. Had thrown error codes related to cam and crank sensors which were replaced along with coil and manifold temp sensors.. Had the 9 volt power to sensors when key was on but the check engine light does not stay on with all the other idiot lights..
I wish people who respond would read the post first..
Original post states,
Cranks,No spark,No fuel pump run, changed some sensors ect...
If it cranks it ain't the neutral safety switch, starter or battery!! WAKE UP!!
Seems the computer is not turning on the coil, injectors or fuel pump for a reason.. Find that reason and you will find the solution to the problem.. Seeing as that the computers logic states are a dealer secrete the poster as I have changed many parts in blind hope that it will fix the problem.. Relays, sensors and ecu computer.. Did a visual check of all harness potential wear spots like where it crosses over the power rack..
Could it be in the wiring harness inside the dash??
Could it be a bad ground??
Can an alternator that has failed cause the computer not to start??
Can a bad oil pressure sensor cause the computer not to start??
Can signal loss from the TCU or BCU to the ECU cause this??
Is there an undocumented kill if the ECU thinks it was in an accident??
I can ground the relay line from the ECU and the fuel pump runs and pressures up and the other relays turn on as well..
This crank but no start problem seems to be common with a lot of 1994-2001 Dodge and Chrysler owners.. All these systems have become interlaced with undocumented safety features that baffle the DIYer..If you have seen this and have fixed it PLEASE RESPOND!!!!

Have the fuel injector pressure regulator checked. Also, make sure the correc fuel pump was installed... I believe the fuel pump for that vehicle is located in the gas tank itself.

No gas getting to the fuel injectors


it should be on the fuel rail itself. with a vacuum hose coming out the top of it. befor you replace it make sure the wiring harness for the injectors is plugged into the main harness

Check for fuel presser bleed down, does the fuel presser hold after you shut it off? or does it fall off? if so check for bad pulsar valve or bad injector ect.

I have a problem no fuel to injectors changed pump checked spark fuel is right up to motor ,But injectors wont fire , how can I fix this ? Is ther a way to wire power to injectors seprat on a switch ,Or Is...


If you are not getting fuel to injectors, and you have a new fuel pump that is getting power and you can hear it run for a few seconds with the key on - engine off, then you most likely have either a plugged fuel filter or faulty fuel pressure regulator.

You can go to autozone, com and register for a free account. Then login, choose vehicle year, make, model, engine size. Lastly, click on view repair manual. Now you have a free repair manual for your car.

If you do not have power to the pump, check that the safety switch for the fuel pump didn't go off. Should be down my passenger or driver kick panel.

Son-in-law did a tune up. Plugs, plug wires,


Do a quick check. Run a wire passed everything from the battery positive terminal to the power connector on the pump, or if you cant get to the pump directly then the first connection you can make to the pump's power supply wire. If she fires up then its a bad fuse, faulty relay or something electronic not putting the power through. If she still refuses to fire it could be the fuel filter filter (to lean), leaking fuel regulator or leaking injectors (too rich). the regulator has a vacuum line on it. If there is a leak in the regulator then fuel vapour is carried by the vacuum line and enriches the air in the intake manifold. The fuel pump has to deliver about 40 - 50 pounds of pressure to the fuel line and has to keep about 90% of that pressure for about 5 minutes after it has been switched off. Dropping pressure indicates poor valves on the pump or leaking injectors. It is not enough that the pump is effective the fuel line should be capable of filling a pint pot in about 15 seconds. If the pump has good pressure (and retention when off) but poor flow then the filter is clogged (this will also kill the pump eventually). As a final check make sure the idle air control valve on the throttle body is clean and functioning as it should.

Fuel system.....all of a sudden nothing , won't start. not getting fuel. Fuel pump is making noise....will start, then stalls, no smell of fuel. Holding gas pedal down, nothing, no smell of fuel.....fuel...


I once worked on a Buick that did this. Try spraying starting fluild in the throttle body. If it starts and runs until it burns the fluid off, replace the fuel filter. If it still doesn't run after this, remove the ignition control module (found under the coil where all your spark plug wires come from, or under the cover on the 4-cylinder model) and have it tested at Auto Zone. If the 'lamp' circuit in the module doesn't work, the fuel injectors won't fire. The PCM uses the reference signal from this module to pulse the fuel injectors in the correct order.

The fuel pump pumps but on start up it dies


Flel regulator will only affect max fuel pressure only will not cause it to not start. try replacing fuel filter first if still does not get fuel then you need to see if it is fuel related or if you have a spark at the spark plugs, pull off a spark plug boot and put screw driver in it hold 1/4 inch away from bare metal and crank engine if you get a spark then it's fuel relateed if no fuel it can be the crank shaft sensor or the cam shaft sensor. let me know if it has fire.
