check the TPS blue + & br - wire should have 4.75~5.25 volts with the key on,What about the power source voltages being all off? Is there any kind of resistance test to check the TPS? The weird thing about this all is that I drove the wheeler just before putting it in garage to fix starter, decompression spring, and FI light wires that were snipped by previous owner !! How could that TPS go bad just sitting there? It did have a miss pretty often but usually took off again with full power. I wish I had a parts wheeler bout now.
Having the tank off and pump disconnected shouldn't interfere with the TPS voltage unless there's a problem with your ECU...I will double check if test light flashes, also will check wires at TPS again. It doesnt click when hooked up to harness. Only when jumped to battery. Injector works too, its resistance is around 11.7 ohms. Also I have turned the key on with the air pressure sensor disconnected along with injector now I got a steady FI light on. How can I clear the codes to start from fresh? Does it clear codes as it recognizes sensors again? Plus I had tank off unhooked from connector, how that cause TPS reading to be off?
Yes it's the programmable race unit, but it's default settings are the same as the OEM your replacing...That what the CD is the programming software, the cord sells for around $300.00 if you can find it...Dust Devil, If I order that 55 dollar ECU, it says it doesnt come with cord? Is that for programming or what? What is the DVD for? Thanks a lot.
Does your F.I light flash when trying to start your motor..?Hey I'm having some serious issues with my injector it won't spit any gas at all and have tested everything not sure what to do. I put a new injector and still nothing also I have the stock ecu and also a new after market so I know it's not that. Anyone have any ideas??
Still sounds like your roll over sensor get the block off from kms. Mine was doing that it would run for 3-4seconds then shut off.Hey if anyone outthere can help me with any info would be really appreciated Ive been trying to solve my problem for 5 months now. The problem injector wont spray gas. second problem when cranking over fi light only flashed continuously so no codes for the diagnostic test. ive tested my roll over sensor many times, voltage to injector, tested the TPS. After all this still nothing so now i have a new injector, new wiring harness and a new ecu. Still nothing wont work. So I disconnected every sensor and tried one at a time. When the TPS was unplugged the buggy would finally spray gas and it would start right off. Great. But only about 3 or 4 seconds after running it just dies like you would shut it off.
