htx-em7-2000 Posted December 9, 2022 Share Posted December 9, 2022 (edited) As the title states. EM7-300 Starts idling for a minute or so normally then shuts down along with no thermostat, battery volt, RPMs, and Road speed gauges don't respond. I also failed to mention that we were getting the flashing red light that does the ENGINE PROTECTION/SHUTDOWN We've replaced the engine speed sensor, thermostat gauge sensor, and ECU temperature sensor checked ohms & resistance, and used a wire jumper on the wiring harness for other sensors. Also took the dash apart to find out the yellow engine malfunction light is not installed and found it has a GPS system because we bought it from a company. Is any more information or pictures needed from me available? Thank you From Houston TX Edited December 10, 2022 by htx-em7-2000 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted December 10, 2022 Share Posted December 10, 2022 What is the oil pressure gauge showing..? That model has a sensor and an oil line to the gauge.. DO NOT.... load the ECM parts cannon!!! I bet this issue is simple... Check the grounds behind the dash behind the gauges and near the fuse panel,,, the ground bolt on the block in front of the starter, the ground on the frame behind the left steer tire,, the ground breaker on the firewall next to the starter relay... there may be an accessory relay under the ashtray, that needs it connections checked.. None of these checks require's you to open your wallet... Jojo Quote Link to comment Share on other sites More sharing options...

htx-em7-2000 Posted December 10, 2022 Author Share Posted December 10, 2022 The oil gauge does respond and this is what it shows when I turn it on and shutdowns shortly after. I researched for the past week before posting about this and read your comments on how to post correctly. We will follow your instructions and report back after. Thanks Jojo.

Joey Mack Posted December 10, 2022 Share Posted December 10, 2022 that gauge is hydraulic, GOOD.. there is a sensor on top of the oil filter pad above the centrifugal filter.. If it is bad, it will tell the EECU that oil pressure is 10 PSI or less, then 10 seconds later , the engine shuts down.. jojo Quote Link to comment Share on other sites More sharing options...
880joe Posted December 10, 2022 Share Posted December 10, 2022 Have you checked water level sensor? Quote Link to comment Share on other sites More sharing options...
htx-em7-2000 Posted December 10, 2022 Author Share Posted December 10, 2022 (edited) top of the oil filter pad above the centrifugal filter...Difficult understanding where. And is the water level sensor on the external water tank Edited December 10, 2022 by htx-em7-2000 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted December 10, 2022 Share Posted December 10, 2022 Thats not a 2000 E-Tech... Thats a CCRS... what does the door tag look like? Quote Link to comment Share on other sites More sharing options...

Joey Mack Posted December 10, 2022 Share Posted December 10, 2022 Hmmmm.. Something doesnt match up here.. I have to admit,,,, I don't recall that engine arrangement in a 2000 model.. Maybe you have a late build for that year.. I'm sorry, but I will wait for some other post's, to see where this goes. I thought that series came out in 2002... jojo Quote Link to comment Share on other sites More sharing options...
880joe Posted December 10, 2022 Share Posted December 10, 2022 Joey are you sure that's not an etech with left side ecm? That ecm number is the newest number my dealer said would fit my early etechs Quote Link to comment Share on other sites More sharing options...
880joe Posted December 10, 2022 Share Posted December 10, 2022 Yes the water level sensor is on the external tank on the firewall Quote Link to comment Share on other sites More sharing options...

So can you get that malfunction light to work that would help some! If it shuts down after a Minute of run time I believe you could have a faulty oil or temp or low water sensor! 1 Quote Link to comment Share on other sites More sharing options...

That ecm number is the newest number my dealer said would fit my early etechs I'm not sure at times.. What has my attention is the centrimax filter style and the plate type oil cooler.. I would have expected the hanging filter, and a bundle type oil cooler.. I also dont see the oil pressure sensor, installed into the filter pad... as far as the ECM,, I thought they were on the right under the heat shield below the turbo, and got moved to the left side due to heat off the exhaust? I guess i'm getting rusty fast, since I have been away from them for a few months.. Jojo Quote Link to comment Share on other sites More sharing options...
880joe Posted December 10, 2022 Share Posted December 10, 2022 (edited) Remember that 1 you built for me was a early etech with plate type oil cooler and left side ecm then we changed it to bundle type cooler and right side ecm Edited December 10, 2022 by 880joe 1 Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted December 10, 2022 Share Posted December 10, 2022 yes, but it was a 2002 engine.. I guess i missed those days at school.. Thanks for clearing that up. I really thought it was a CCRS... I have been confused before, when it comes to what year a change was made.. Jojo Quote Link to comment Share on other sites More sharing options...
JoeH Posted December 10, 2022 Share Posted December 10, 2022 2001 saw the changeover to the left side ecm I believe. With info provided initially I'm thinking this is a simple power issue. He said engine dies, as well as battery voltage. This tells me there's a power supply fault. Do these use the relay under the ash tray for power like the pre-Etech R models? Check your ignition switch circuitry. Quote Link to comment Share on other sites More sharing options...
JoeH Posted December 10, 2022 Share Posted December 10, 2022 Those relays are junk. The ones from Mack last... 2 years at best on my '95 R model... Quote Link to comment Share on other sites More sharing options...
Mackpro Posted December 10, 2022 Share Posted December 10, 2022 The LSR ( Left Side Re-design) started in early February of 2000. I thought I’d was only on the CCRS engines as well. But the early Etech’s had it to . 1 Quote Link to comment Share on other sites More sharing options...
