My other 04 jeep spec. edit. 4.0L has an open circuit on #6 injector how do I test for voltage and ground on the plug.. Thanks Ray

the ECM already is working the injector
check injector harness connections and the connections at the
you can try substituting the ECM with a known good unit as a last resort to prove a point

Fuse to my fuel injector is popping and my car dies

It could be a short in the injector circuit (and it's not that complicated), or it could be a shorted injector itself. You may be able to isolate and find it.
Begin by disconnecting all six injector connectors from the injectors. Now put a new fuse into the injector fuse slot and turn the key to on, not start. If the fuse blows again, there must be a short in the circuit-I'll get to that later. If the fuse stays good, then put one injector connector back on -key still on. Watch for the fuse to blow when you connect each individual injector back on. If you have a shorted injector (internally bad), it can blow the fuse and stop the injector power circuit. That injector must be replaced. The injectors can also be checked with a volt ohm meter, if you have one.

So if your circuit is bad, from fuse to the injector harness connector a pink/black wire supplies constant battery voltage to all injectors-always hot in run or start-each injector gets a splice from this pink/black wire. The other wire at each injector is the dark blue ground wire. From each side of the engine the ground wires splice together-so 3 to each side-and head into the ecm on the 22 pin blue ecm connector. The pin numbers are D3 and D9. When the computer internally grounds one side or the other for a split second, that is where you get the pulse-the injector solenoid is energized, opening the injector for fuel to spray out. So now you know where all the injector circuit is, and where to look for a short. Having a DVOM would help you immensely in troubleshooting any thing automotive. Good luck, let me know what you find.

Did you clear the codes? Car may still be in limp mode...
Also the 303 is odd. Are the sparks good on #3? May have an issue with coil or ignition module.

Ford 2003 escape codes readed

Cauases or fault codes are not cut and dry, but here are the possible causes of codes P0316 and P0306 which are related codes.
P0316 - Engine Misfire Detected on Startup
Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- Engine fails to start
- Engine runs rough Possible causes - Crankshaft Position (CKP) sensor harness is open or shorted
- Crankshaft Position (CKP) sensor circuit poor electrical connection
- Faulty Crankshaft Position (CKP)
- Ignition System
- Fuel Injectors
- Running out of fuel
- Fuel Quality
- Faulty Engine Control Module (ECM) P0306 - Cylinder 6 Misfire Detected Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- Lack/loss of power
- Hard start
- Engine hesitation
Possible causes - Faulty spark plug 6
- Faulty ignition coil 6
- Ignition coil 6 harness is open or shorted
- Ignition coil 6 poor electrical connection
- Clogged or faulty fuel injector 6
- Injector 6 harness is open or shorted
- Injector 6 poor electrical connection
- Improper spark plug 6
- Insufficient cylinder 6 compression
- Incorrect fuel pressure
- Intake air leak

No.6 fuel injetion stuck open

The only fix for that is to replace the #6 fuel injector or repair the short in the fuel injector control circuit.

I have replaced plugs wires coil pack tps sensor and idle air control valve and still has cylinder 6 misfire i have also checked the compression in cylinder 5 and 6 and they are both 125 so i know thats...

yes it is probably the injector or injector wiring harness.

Start by checking the resistance of the injector at #5 and compare value to #6, they should be the same.
Check the condition of the injector plug to #5, look for corrosion or broken wires at the connection.
Do you have an electrical pulse at the #5 injector connection with the engine running?
Have you verified spark at the plug?

if you have spark, compression, and fuel pressure then your assumption of a bad injector(or wiring) is correct.

Here is a redneck trick to get a stuck injector going, otherwise you will have to replace the injector.

Changed engine and we have no spark, no injector pulse and no fuel pump operation Just bought a Snap-on Verus and still cant get in what do i do now?

Sounds like you missed a ground connection, probably coming out of the injector harnass or the one near the shock tower where the main harnass goes through firewall to PCM.

2002 ford escape 3.0L DTC P0305and P0306 what would you ck

P0305 - Cylinder 5 Misfire Detected
P0306 - Cylinder 6 Misfire Detected

When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, The Powertrain Control Module (PCM) or Electronic Control Module (ECM) can determine that a misfire is occurring.

When is the code detected?
- Engine Cylinder #5 and #6 is Misfiring.

- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/loss of power
- Hard start
- Engine hesitation

Possible Causes:
- Improper spark plug at cylinder #5 and #6
- Insufficient compression at cylinder #5 and #6
- Incorrect fuel pressure
- The injector circuit is open or shorted at cylinder #5 and #6
- Fuel injector #5 and #6 may be faulty
- Intake air leak at cyli

Possible Solution:
- Perform Injector Service
- Replaced Spark Plug #5 and #6
- Replaced Injector #5 and #6
- Replaced Ignition Coil #5 and #6

Hope helps.

The car is running on 5 cylinders.I changed the plugs,put in injector cleaner and even changed the lead on the number 6 plug as that appeared to be the problem plug. What next

Unplug the battery cable. Pull out connectors to the injectors, one at a time and measure the impedance on the injector with a digital multimeter. The reading should not be higher than around 10-12 ohms. If you get a really high reading or indication of open circuit then the injector is burn out. If you get really low reading like 1 ohm vice versa, then injector is shorted out. If you found the burnt injector, and replaced it with a good one the car will run a lot smoother since all cylinders are operating.

Fuel injecter fuse blow imeditaly when ignition turn on

sounds like a short in the wiring from the fuse and the fuel injector junction block. GM like most fuel injection systems control injector firing by the computer providing ground to each injector in pairs or individually. The fuel injector fuse provides power to the injectors using splices therefore enabling one wire to feed 6 injectors. A shorted wire at any of these wires will blow the fuse. On one rare incident I found a faulty computer caused the fuse to blow. A shorted injector will just cause a rough running problem due to the injector stuck either open or closed.
