Re: RODEO 99 ECM PROBLEM
That can happen for several reasons the least being the ecm. first thing is it could be a weak fuel pumpand the only way to check this is with a fuel pressure gauge. it should be between 17 and 25 psi. next it could be the TPS(throttle position sensor) this controls your idle. this is located on the throttle body has a weatherproof plug and is held with (2) screws . next is the engine speed sensor this helps the ecm adjust the fuel/air mixture in conjunction with the TPS,IAC valve,O2 sensor<and the egr valve. to pinpoint the sensor problem you have to have a diagnostic scan done. please rate this.......thanks

I think there is a wireing harness running from the passanger side front of the engine accross to the inner guard then to the firewall, try bending slightly in diffrent spots while someone is cranking the motor. There is a wire in there that brakes & will stop it running. It happened to me & the mtor was cutting in & out but managed to keep it running till I got to wrk but once turned off that was the end of it. Mine is a 99 rodeo with 6VD1 3.2 litre engine
Hi, first check for sparks by pulling a plug wire off and sticking a phillips screwdriver in the boot. Lay the screwdriver/boot down on the engine with the screwdriver shaft about 1/4 inch from the engine, and crank the engine to see if sparks jump from the screwdriver. If no sparks, suspect you may have a bad crankshaft position sensor, but first verify you have voltage to the coil using a 12 volt test light. If no voltage to the coil, check ECM-1 fuse. See diagram below and let me know if you have questions.
Perhaps in the ECM/ECU, you would have to go without a car for a bit to send it off, though.
Physically, it only has a bleeder valve in the fuel rail, just underneath the plastic
cover on the engine, follow the silver rail that runs across the front
and goes back on both sides, it's on the right side, just under the
left-side blue refrigerant valve cover.
Underhood fuse block swap out relay #7 thats the ECM relay. Ground Circuits Using a DVOM, touch negative voltmeter lead to a good ground. Touch positive voltmeter lead to each ground terminal. With vehicle running, voltmeter should indicate less than one volt. If reading is greater than one volt, check for open, corrosion and loose connection on ground lead. See ECM GROUND LOCATION table for ECM ground location. Page 1 of 1 SYSTEM/COMPONENT TESTS - 2.6L EFI -1994 Isuzu Rodeo
i gather this is diesel engine.
the fuel cut solenoid is on the rear of the injector pump (left side of engine) there were a couple of different injector pumps some had 2 solenoids on pump but one is fuel cut solenoid.
can be purchashed from dealer,diesel injection service centres and several different spare parts outlets.
you're having the same problem i had with my 99 isuzu rodeo 2 wd 3.2 i paid a muffler guy over $600 to replace those catalytic converters, if you're good at welding you could do the welding yourself after buying the catalytics, basiclly i seen them just cut them off and welded them back on
did you upgrade any of your fuel system components? if not you might want to at least check out the fuel sending unit and pump motor... you may be pumping the amount of fuel that the old engine wanted but your new engine doesn't quite want that much.. hope that helps
