Hi, I would start with your ECU. I just spent nearly three loooooooooong months with the same issue and replaced 10 items in the engine bay to try to figure out the busted bit. It was a fried ECU all along. I'm not saying thats your problem area, but it might save you a tonne of time starting...

Hi, anyone driven their jeep to Devils Tower, WY? I'd love to see some pics of your Jeeps near my favourite US location. Thanks Glen UK.

Hi all, is an XJ ECU/ECM compatible with a YJ? If it's the same year and engine? I'm having the devil's own job locating an ECU for my 2.5l 4cyl here in the UK. Zero luck. USA seems to be my option but they are super expensive. Just wondered if I have other options? Thank all!

Hi all, whilst on the continued hunt for my YJ not powering the injector I came across this connector hanging around under the battery. It's looking dirty so I assume it's not been connected to anything for a long while but it is connected by a wire to the Diag box by my battery. Any clues what...

Ah ok, I was in bright sunny conditions. Figured it was a bright flash! I'll try again in the dark tomorrow. Thanks for the pointer.

Hi, I've bought a noid light to test my Injector. Looked elsewhere on here for help but they are quite old posts so apologies for resurrecting. Plugged the noid in to the harness and cranked the Jeep, no light. I've read that light is good and no light is bad ? The ECU is sending a pulse to the...

Thanks, I'll do that this morning. Finally got a sunny day over here to do some work.

I don't know what a carb is but it's gotta be better than the quagmire that is under my hood!

Thanks Gila, Just checked them out. That's not bad even with shipping. Probably get the new one rather than send mine over for refurb. Just can't seem to get mine to spray the fuel. Pulse is there, noid is showing good power pulse etc, fuel is there, just won't let the fuel through, so I think...

Hi, can anyone tell me from the pictures if there is anything obviously wrong with my single point injector for my 2.5l 4cyl? Before I start hunting for a new one around the globe. ( It's getting power and ground from the ECU but not spraying at all despite having fuel at the inlet) Thanks all.

Yep, cranking the engine.

I think I'm on the cusp of fixing my non starting jeep! 1. Finally got a spark from the coil to the dizzy cap. 2. sparks from all four plugs. 3. I'm getting fuel at the single point injector. 4.The injector works with the 9v battery test. Clicking fine 5. Ive got power going into the injector...

Hi all. Does anyone know what the hose is called or the part number is for the single hose that should be here instead of these three? Looks like a makeshift repair but doesn't look very efficient? Thanks all.

Does anyone have a photo or a diagram of the ECU/ ECM harness or connector so I can see which pin is the one firing a signal to the single injector please? I've been told it's number 21 but don't know which one that is?? 1988, 2.5 4cyl SPEFI Thanks!

Jaguar Land Rover own Range Rover as a marque. So a RR and LR are different markets but they are both Land Rovers. In the UK, RR Sport and Vogue are the most stolen vehicles in 2023 and more an more insurance companies are refusing to insure them.

100% yes! Haha. Very badly made. But unlike Jeeps, they were not iconic, not cool, not fun and not worth throwing money at because you love them. 😄 A lot of them went off road but not through choice, though crap brakes and a dodgy suspension😉

ECU has been refurbed and seems to be working fine- better than before anyway! I've narrowed down my issue to the single point injector. Spark from the coil, spark on the ignition wire, spark at all four plugs. Fuel is hitting the throttle body but does not seem to be allowed into the injector...

Does anyone know what voltage I should be looking for on the two wires that power the single injector please? One apparently is fed by pin 21 off the ECU, so I should see something there when I turn her on I guess.....??

Hi all, bit of an update to my no spark issue. I eventually sent the ECM off to a local PCB / ECM repair place who refurbed it. Not cheap,but at least it would be another item I can eliminate. Plugged it in and no joy.BUT!! things have changed..... I now get a powerful and visible spark from...
