Failed attempt at resurrecting a 93 Twin Turbo FD. What to do next?
 

Hi community need some advice. At best I'm an amateur mechanic...more of a hobbyist. My landlord asked me to work on his 93 twin turbo FD. The car was completely dead. No crank, no start, no nothing. It had sat for some 7 or 8 years getting water poured directly onto the hood and into engine bay courtesy of the buildings gutter outlet. This will become relevant shortly.

Long story short I decided to remove the rats nest to service the fuel injectors. When I was able to see all of the wiring underneath the exhaust manifold/rats nest, I discovered two things. (1) the cars wiring had been worked on previously and it wasn't in the factory configuration. I'll list the modifications done to the vehicle below. (2) many of the smaller gauge wires to the multitude of electrical connectors were severely rusted and basically disintegrating. I began to solder as many as I could and there were a lot. Unfortunately some wires were beyond repair and many connectors simply snapped off where the wire and connector meet preventing me from attempting to repair them. I ended up with 5 connectors that couldn't be connected to their respective components. Don't ask me what components they go to because this car is so complex that I have no idea. The point is there are multiple connections that aren't being made and multiple solder points in very compromised wiring.

I put everything back to together and the car cranked but not surprisingly it wouldn't start. I've got fuel going to the fuel injectors but no spark at the plugs and not sure that the injectors are actually injecting fuel (can't hear them clicking). I've put an inordinate amount of time into this car and frankly it is beyond my pay grade; I don't have the expertise to fix this car.

I would like to hear what the members of this community would do next so I can give my landlord some sound advice. Would you sell the beast? How much would it cost to have it repaired by a qualified mechanic? Does the entire twin turbo wiring complex need to be fabricated from scratch? What are your thoughts in general?

More data about the car

Known modifications per the owner: Turbos polished, catalytic removed and custom exhaust installed, ECM modified or possibly replaced to deliver more power, and I believe he said the fuel injectors were replaced or modified to deliver more fuel.

Car is registered in California and registration is not up to date. In other words, it was not placed in non-op status and it has been accruing registration late fees for 10 to 15 years.

What I did: Fuel tank was removed, cleaned and treated for rust. Fuel pump and fuel filter was replaced. Fuel lines flushed and cleaned. Fuel injectors tested and replaced/repaired as needed. Removed aftermarket alarm. I tested compression using a standard compression tester and readings seemed to be within range. It was a while ago and I don't recall the PSI. Spark plugs replaced. Belts replaced. Oil changed.

Cosmetics: Body is dead straight with no damage. Paint is severely faded and appearing to rust in some areas. Interior is essentially ruined from water and moisture. Leather and carpet is full of mold.

That's all I got guys. Its a hot mess. I look forward to reading your responses.

Best!

I just scanned. Sell it. You’ll never get it running again. And stop double posting the same lengthy thread. Pick a section.

many threads started concerning the issues with this FD. only one will suffice and keeping it on going. the thread in the 3rd gen section is the best place to be. it will get the most attention from those that know the FD.

closing this thread.
