Is there an injector pulse on a Ford Ranger?
Is there an injector pulse on a Ford Ranger?
No injector pulse! Its a 98 ranger 3.0 2wd with auto trans, 203,000 miles. Im thinking the pcm is bad but want a second opinion, the pcm has been fried before due to the battery being jumped wrong.
Why does my Ford Ranger have no spark?
Fuel pump turns on at KOEO but does not turn off after 1-2 seconds like normal. Appears to have no spark or injector pulse. The Check Engine light does NOT come on at any point when trying to start. SPARK: Looked for spark with inline spark test light and also old fashioned method – plug in wire held against good ground.
Why is my fuel pump not working in my Ford Ranger?
Cycle the ignition key from off to on several times to pressurize the system. System pressure should be greater that 45 psi. If no fuel pressure develops in the system, the most likely causes are the fuel-pump fuse, fuel-pump relay, or fuel pump.
What should resistance be on Ford Ranger fuel injection?
Readings of 0 ohms indicate a shorted injector and readings of infinite resistance indicate an open injector. Resistance values of 10 to 16 ohms are normal.

Why does my Ford Ranger crank no start?
In this video we cover some basics on finding the cause for a crank no start on a Ford Ranger. Many Ford vehicles have the same ignition and fuel design. I eventually trace the issue to a defective inertia switch, causing an electrical issue not allowing the fuel pump to run. Thanks for watching!

What causes no power to fuel injector pulse?
Ans: The engine control unit is the electronic brain that used to control the fuel injector pulse by gathering data from various sensors along the fuel line Question: What causes no power to fuel injectors?
What causes no start on a Ford pick up?
If no voltage is present, as your helper cranks the engine, then the cause of no fuel condition is due to either a bad fuse, fuel pump relay, or inertia switch. One of the most overlooked areas, when testing a hard to diagnose no start, is the mechanical condition of your 4.9L, 5.0L or 5.8L Ford car, pick up, van or SUV.
What to do if there is no power in the injector?
Check the fuses if there is no power. Replace the ignition module if there is power supplied to the injector but no ground during cranking. If the engine runs, but has a misfire, test the injector by measuring the resistance of the injector.

What does it mean when there is no injector pulse?
In case of that, there is no injector pulse or spark, this means that is your ECU has failed in operating in this case you have to get your ECU changed or visit an expert.

What causes a no start no injector pulse?
The first time I ran into one of these, I mistakenly replaced the engine computer in an attempt to fix the no injector pulse condition. It is strange that one shorted fuel injector can cause all the other injectors to not fire, but this is exactly what can happen with a group fired system.
How does the fuel injection work on a Ford Ranger?
Troubleshooting the fuel-injection system in the Ford Ranger can be a daunting task. Understanding how the system functions makes this system easier to diagnose and repair. High-pressure fuel is supplied to the fuel injector by the fuel pump.
What to do if there is no injector pulse?
If after all this you got the same result, so it’s time to check the injectors itself if there is no injector pulse on one cylinder, by try to unplug injectors one at a time, if the engine starts when a particular injector is unplugged so that it is the defected one that needs to be replaced
What should the fuel pressure be on a Ford Ranger?
System pressure should be greater that 45 psi. If no fuel pressure develops in the system, the most likely causes are the fuel-pump fuse, fuel-pump relay, or fuel pump. Check the fuel-pump fuse at the the under-hood fuse block using the circuit tester.
