The ECU is under either the drivers seat or passengers. You can't miss it...it's a big hunk of metal. Also check the ground wire going from the body to the engine...it's on the drivers side..I think. It's a big braided bit of copper.
I've owned one of these for a few years back in the late 80's. Very fun car...and yes...$$$ to fix if it went wrong on you.

|club327||The Ljetronic, like most efi's, feeds a constant 12v to its injectors and switches them on and off by grounding the negative wires. When the engine is rotating/running the negative feed to the injectors would be triggering on and off.........the more fuel required the longer the injectors would be earthed. From memory were talking 3/1000 of a second on average duty cycle. Now in your case we've got a huge dump of gasoline for some reason. You're saying the injectors are spraying without the engine running? Well that sounds like the injectors are constantly grounded to earth which would cause them to be permanently opened. But my guess is that the efi computer is not receiving the signal from the temperature sensor and thinks the engine's is -50 degrees cold therefore opening the injectors for most of the cycles causing a major flood. Remove the spark plugs, kill the ignition and crank the engine. You'll probably see raw fuel squirting out from the spark plug holes. Check the connections at the temperature sensor for excessive corrosion - which is usually a green powdery build up (the sensors are normally near the thermostat housing). Carefully clean the connections with a scraper but trying not to open the female tangs too much or they'd become weak. Finally give the connections a spray with WD40 or similar and reconnect the plug. Now crank the engine to purge the excess fuel from the cylinders, clean the plugs and refit them. If this is the fault then the engine should start. Once sorted out you will need to change the engine oil due to the fuel contamination. Good luck......if it's not that......burn it!|

To be honest I would run as far away from that money pit before you spend another second thinking of fixing it, I have known two people that had them when new and got rid of them fast.
Worse than junk they are foreign...impossible to find parts for...junk. The scrap yard should net you a $100.
Really...run far away.

'84 Renault Fuego Turbo Problems (Bosh L-Jetronic FI)
Ok the car is a 1984 1.6 Liter Renault Fuego Turbo. This car has been sittin in our driveway for a while now and I'm starting to get intrested in getting it running. From the research I've done on it, it seems to have a Bosh L-Jetronic Fuel Injection system with a 5CU Lucas ECU. Now my first problem is that I can't seem to locate the ECU and my second problem is that as soon as I turn over the key every injector is wide open allowing the fuel pump to pump gas straight into the cylinders before ever starting the engine. Can anyone help me out here?
