    Ford LRG 425 shuts down after running for 35 seconds

    Birken - I did not have my meter on the correct range when I did my initial reading for the temp sensor. I went back a verified and it does read ~12k which seems correct. I also put a 10k resistor in place of the sender with the same results. Like you, the reduced RPM running screwed up my...

    Ford LRG 425 shuts down after running for 35 seconds

    Did some more troubleshooting this morning: Tested the B+ voltage at the coil pack. It was 14.2v with the engine running. It stayed at this voltage for about a second or so after the engine stopped. So the coil pack was getting voltage when the engine stopped. I don't have a scope to test...

    Ford LRG 425 shuts down after running for 35 seconds

    Thanks Birken for the pinout. Just seem strange that the engine stops exactly at 35 seconds every time. While troubleshooting I have started the engine 20+ times and it is always consistent. Like you said could be the ignition module giving up the ghost but at $600 it's a part that I better be...

    Ford LRG 425 shuts down after running for 35 seconds

    Throttle (i.e. gas valve) remains open when the engine dies. The ignition input voltage (i.e. Ignition ON) remains on BUT the spark to the plugs get stop and then the engine dies. So there is some input to the ignition module or the ignition module itself that is causing the spark to stop even...

    Software For Tracking Customer Equipment Maintenance?

    Take a look at this program. Easy to customize. They have a 30 day trial. If you decide to buy I think it's on like $25. http://www.cat.cc/CAR/index.htm

    Ford LRG 425 shuts down after running for 35 seconds

    This is a new thread but it is a continuation of trying to debug this engine problem that started with a previous thread about the LRG 425 not starting. I am able to get the engine to start reliably now, but it shuts down after running for 35 seconds. I've started the engine 7-8 times and it...

    No Start Ford LRG 425

    Thanks for the link. It appears that Melling, Sealed Power, Diamond Power and EngineTech all make a compatible oil pump. Do you have any experience/recommendation with any of these?

    Had to go back to 1998-2001 Ford Ranger (also Mazda B2500) appears to be the correct part.

    Ford Ranger doesn't seem like to same part. Could it be some other Ford you are thinking of?

    Took off the timing belt cover and found that the camshaft sprocket was not aligned with TDC. Took off timing belt and aligned the camshaft sprocket. Put everything back together and the engine started right up. After running for about a minute it shut down due to low oil pressure. Put...

    Grandpa -where would the CPS be on this engine? Is there a way to verify if the current sensor is working? Do you have a part number for a replacement, if needed?

    Got the air filter off. Tried both carb cleaner and ether. Sprayed for about 1.5 - 2 secs into the throttle body while cranking. Engine didn't even pop. Getting good spark. Engine was heated to 90 degrees. What should be checked next?

    The engine is controlled by a Ford ICM (see picture). It also has engine interface module for the generator. See pictures

    Vogt - the air filter is difficult to get off without taking the whole generator top off - it is right up against the cover. Would it be possible to spray the carb cleaner in the pictured test port? Trying to plan ahead on the outcome of the carb cleaner test. If the engine starts with...

    I do not have a spark tester - I just let it arc to a bolt. The machine is processor controlled. I will try to get specific details/pictures later today and post. Compression test was a dry test

    Can’t get our 2006 Ford LRG425 (SN# 06VG56426) engine that is part of an Eaton 21kW backup generator system. Here are the particulars: Engine configured for LP gas. Verified shut-off valve opens properly and I see ½ PSI before entering the zero pressure LC-50 throttle body. Verified that...
