Make Late Model Restoration your one-stop shop for Ford Mustang parts ranging from restoration to performance. Inferred Airflow in lb/min. I changed the pip (pick up coil) had the ignition control module checked @2 different places and both said it was good. This provides the PCM information on engine load. It is suitable for cars and light commercial vehicles with up to 5 l engine capacity and 312 hp engine power, the first installation in series production cars was 1998. Technically, all EFI systems are sequential in that once all cylinders have been injected, the sequence starts from the beginning again. Since then, fuel injectors have been the primary means of getting gasoline into the engine cylinder so it can combust and you can drive. Ok so here's the deal. The crank sensor has been checked and I also tried swapping the ecu with one from a 91 ranger with no luck. It seems any infomation i try to find on this does not exist. Also found that the boost sensor(MAP) values were not responding and replaced it with new one but still no voltage at injectors. If an injector, or injectors, are not on spec, the ECU will attempt to correct flow delivery via altering injector pulse, but it cannot correct the faulty injector(s). 5L EcoBoost TM V6 twin-turbocharged, direct-IT TINGLES SPINES like the electric buzz of night injection engine really gets the heart pounding. No machining required, capable of running 500 plus BHP. Decreasing the on time of each injector pulse leans the A/F mixture and reduces the volume of fuel sprayed into the engine. 3L DIT diesel engine. We are able to test and repair these injectors. Not only do the injector drivers get hot, but the injectors themselves heat up from the current passing through them. Will NOT fit National RV with DuraFrame. What I have is: Fuel pressure of 38 to 40 psi, good compression and ample spark. Ford Transit 2000 - 2001 2. Injectors should fire twice for each revolution of the engine. New carburetor kits, currently being produced. then, it will outpout two PWM. Injector Pulse Width #4; Table of Enhanced Parameters for Ford Table of Enhanced Parameters for Chrysler. While some. Module takes a thin 5. Powertrain Control Module (PCM) The PCM maintains proper spark and fuel injection timing for all driving conditions. and later came to the conclusion that a injector was leaking. The Maddox® Basic Fuel Injection Service Kit provides everything needed to perform accurate running, residual, rail and flow rate pressure tests on most fuel injection systems.

Replace a defective fuel injector and get rid of poor fuel economy and sluggish performance. injection pulse time (ti) in order to maintain a Lambda = 1. GM: Base Pulse Width (BPW) Ideally, n = PV /RT and then injector pulse = n / injector flow constant. Since then, fuel injectors have been the primary means of getting gasoline into the engine cylinder so it can combust and you can drive. Joined: Sep 2005 #1. Also found that the boost sensor(MAP) values were not responding and replaced it with new one but still no voltage at injectors. Injectors should fire twice for each revolution of the engine. The first system uses continuous injection where the fuel is squirted into the inlet port all the time the engine is running. This type of driver works by supplying 12 volts to the injectors and the ECU turns it on and off to establish a fuel injector pulse. 5-2002 Dodge; Map Sensor Placement 2003-2007 Dodge; MAP Sensor Placement 2007. 0L Split Port for almost a decade. For transmission strategies, the MAF sensor is used to regulate Electronic Pressure Control (EPC), shift and torque converter clutch scheduling. Ok so here's the deal. In the past, fuel pump manufacturers have rated their offerings based on gallons-per-hour, free-flow (no test pressure), and with no reference to test voltage. asked Dec 15, 2013 by Michael. Some for research, some for validation, and some just for the sake of looking. The following tutorial will help you to test the fuel pump: How To Test The Fuel Pump -No Start Test (Ford 4. Step 5: Repeat with all injectors. 3Overkill Junior Member. Now remove the three 9/16” nuts and washers holding the injection pump to the injection pump gear housing. The ecu uses the signal from the cam sensor to pulse the ground to the injectors. An available, all-new 3. The pilot and main injection events have an additional phase of lower current, which modulates from 12 to 14 A. I have triple checked the grounds made sure the pcm has constant voltage. 9ms of injection time only gets us 0. : Posting here for greater exposure, hoping some Ford guys are amongst us. It has actually been delivering results, but the technology can lead to more time in the repair shop. The 160-horsepower, 4. Everything checks out ok, i have spark, 40 psi fuel pressure but I have no injector pulse.

The new version is more intuitive. 5ms and has fixed my problem. 6l EDIS Strategy. If not, further diagnosis is required. A fuel injection kit is a selection of components that work together to deliver the right amount of fuel to the engine at the right time. The MAF sensor output signal is used by the powertrain control module to calculate injector pulse width. As with MAP systems, lookup tables in the PCM then retrieve a base injector on-time command. Vehicle: Ford AUII 2000 4. The injector data given is based on manufacturer's published data and are given for the specific base fuel pressure listed (recommend high base pressure for small injectors. The positive 12V wire in the injector pigtail has positive 12V on it any time the key (ignition) is on. Louis, MO Matt Dixon, Assistant Professor, SIUC. 1998 Ford F-150 v6 4. This cluster entails a Speedometer, Tachometer, Fuel, Oil, Temp, and Volt gauges in an injection molded ABS housing. I installed the verus on it and no codes are available. It is possible for a very large injector (90 + lbs/hr) to jam at 100+ psi of fuel pressure. This amount of increase or decrease of the injection pulse width is known as the Adaptation Value. This page is intended for people who want to learn about the Ford EDIS (Electronic Distributorless Ignition System). No machining required, capable of running 500 plus BHP.

For 2011-2016 6. 4 degrees - Single spray cone. I think the car would at least sputter a bit if even half the cylinders had working injectors (dont ask =P), so it is probably a central fuel delivery problem. This page is intended for people who want to learn about the Ford EDIS (Electronic Distributorless Ignition System). 0 motor The 6 cyclinder motor has 6 fuel injectors. Ford is a totally new design for the US Navy and Northrop Grumman Shipbuilding. P0202 Cylinder 2 Injector Circuit Malfunction is set if the PCM finds a low or high voltage drop, resistance at the injector, or fault in the wiring. The IAT sensor (4. Injector pulse width is the length of time the injector is open. Ford had issued a customer satisfaction program 07m08 to cover the fuel injectors to 11 years or 120,000 miles but since I was at almost 9 years and 134,000 miles Ford no longer claims no responsibility for the cost of repair of a known and published problem or to its customer. Flow rates can only be changed on a limited basis by raising or lowering the system’s fuel pressure set point (the measured pressure with no vacuum or pressure on the regulator to manifold port). Unit injector system: optimal pressure in each cylinder The unit injector system is an electronically controlled system developed by Bosch for diesel direct injection. The longer the ground signal is on, the more fuel is injected into the engine. 2 circuit ignition wire spark plug ignition coil fuel pump inlet strainer plugged restricted fuel supply line fuel pump module fuel pressure leak down fuel injector engine mechanical problem.

The rpm drop that results, if any, is then read. The rpm drop that results, if any, is then read. You can do the swap with the exhaust in place. To make sure the ECU is getting an RPM signal, look at the “RPM” in the data monitor. This shifts the spool valve in the injector to the open state. This page is intended for people who want to learn about the Ford EDIS (Electronic Distributorless Ignition System). No injector pulse width, however, is preventing it from running. If it has fuel pressure, then check the injectors for power on one side, and pulse on the ground side. High Performance.
