A buddy of mine has a early 90's tracker and if he pours gas down the carb. it will run but otherwise the injectors wont pulse he's at his witts end he's takin it to the shop and they could'nt figure it out so got another brain still no worky so he's ready to put a carburator on it I showed him northcoast's writeup on installing the toyota carburator but I did'nt know if the intake is the same on the 1.6 as the 1.3 any one know or have any ideas why the fuel injection wont pulse?
By the way, the "early 90's Tracker" didn't HAVE a carburetor. It's a throttle-body fuel injection (TBI) machine. Did you check your fuel pressure? My guess is fuel pump, or fuel pump relay. If it was the fuel filter, it probably would have faded slowly.
When I was installing my '91, I left out the noise suppressor because I assumed it was just for the radio. Turns out it feeds the tach signal from the distributor to the ecm. Without that signal, the ecm won't issue the pulses to the injector. Hope this helps.
On my 91 1.3, the ecu was bad.
Figure out which wire goes from the injector to the ECU.
Cut this wire and splice jump this wire from the injecter to the battery. If the engine starts, run a wire from the injecter to a fuse in the fuse block that is hot when the key is in the start and run position. Make sure that the power is off to the fuse when the ignition is off.
I have been running mine like this all summer and have not had any problems. Don't know what the long term effects will be though. The Check Engine light will stay on.
Cap34 may have solved the problem I e-mailed your responses to my friend and he stated the previous owner cut out the noise suppresser thinking it was causing the rig not to start in the first place. So the next question anyone got one plus any wiring it may need?
Thanks for all your help!,
PS. The sooner he get his tracker going the sooner he quits wheeling in a jeep!
