I performed the FSM checks and have voltage and continuity to the EFI but it's not getting the injectors going. it starts great on starting fluid. All indications are Bad ECU. This guy seems like a viable option for $140.
How do I get the wiring harness disconnected from the ECU? I hate all...
I got the ECU pulled out finally. getting the volt meter into those connectors is a b'atch. voltage to EFI is good, voltage to ground good. I guess I need to send it in. Anyone know how those harness clips come off the ECU? I don't want to scre that up.
I found these ECU guys that will...
How the heck do you get the ECU open? i unscrewed the brackets and now what? This is my first attempt at diagnostics. The EFI is not running. Fusible links checked, new Relay; now what? I gotta get to work in this thing ASAP.
my 91 ran fine and fast getting home and now doesn't have injectors firing. Runs on starting fluid. Plenty of fuel pressure in the line to Cold Start Injector. Replaced the EFI Relay with one off Amazon; that didn't help then ordered the OEM from Matt yesterday in case the Amazon was junk. The...
For a 91 3FE? chazsedona@icloud.com Do you know where the fuel pump relay and fuse might be? Truck started on fluid but then starves no gas. Ran great like 75 MPH getting home from work the other day. This morning nada.... Thanks
where is the fuel pump relay? i can't seem to find the relay and fuse map. Is there a fuel pump fuse? Cruiser fired up on starting fluid then starved several times this morning. ordered a fuel filter to start. yeah getting to the pump is kinda tough.
I have fuel spray. Anyone know where I can find a new CSI? The guys at BTB Products at 7025681511 are great but don't have one. I have bought from them years ago.
no on fuel verification to banjo. loosen it up a bit and check for leak?
no on +12v to CSI connector
where is "ECU connector E4 pin 11"?
I ordered the CSI on eBay so when it gets here I'll install and see if I get an easy start. This existing CSI is original '92 I think maybe '91
thanks...
I did the OHM check procedure and getting 8 OHM. Anyone know where to find a CSI for 3FE? I can't remember the guys in Las Vegas but they were good and close.
well then see if you can find US or Japanese built 4 port injectors. After stripping off all the smog stuff, I have the fastest 3FE in 3 counties.
I can try to dig back in eBay and find them.
