After having sat for a mere 21 years I decided recently to try to start my Gen 2. I've done the following:

I removed and replaced the fuel cell, which had deterioriated into a literal pile of debris--to the point where after removing the "behind the seat" panel the fuel cell and foam were unrecognizable. I have photos if anyone cares.

Thanks to Spec Racer Sports in Houston, who coincidentally had replaced a customer's fuel cell the day before I went dumpster diving and brought home a used but perfectly servicable fuel cell.

I inspected and eventually installed the fuel cell but did NOT connect the Return hose (below).

I changed the oil and filter.

I filled the cooling system (per Mumm Brothers' method).

I removed the alternator and spark plugs, and squirted a liberal amount of oil down into the cylinders and then cranked the engine to distribute it.

I reinstalled the plugs and alternator.

I poured four gallons of fresh ethanol-free fuel into the fuel cell.

I connected the Return line to a length of clear vinyl tubing which I ran into a container.

I grounded the fuel pump connection in the EEC test header.

I turned on the Master and Ignition switches and verified that YELLOW FUEL, FOLLOWED BY CLEAR FUEL came out of the return line.

I disconnected the fuel pump connection in the EEC header.

I cranked the engine to start: The engine did not even sound like it was interested in starting.

I sprayed starter fluid into the intake box and cranked again: The engine fired but would not stay lit.

I sprayed starter fluid into the intake box again and cranked again, this time working the accelerator pedal to try and keep it running. It ran briefly off of the starter fluid and did try to run on the fuel, but just sputtered and quit. I tried this a couple of more times with similar results.

I do not remember the state of the car after its last race in October, 2004. I did not intend for that to be its last race--it just became overcome by events and wound up sitting for 21 years.

Although I did drain the cooling system I imagine that as far as the engine goes I just shut it off without draining the fuel from the system.

I know that fuel left more than a year or so can foul an lawnmower carburetor. I assume that 20 year old fuel do the same thing to the SRFs fuel injection system.

Finally, I have not yet reached out to the CSRs about this.

So, my question is: Assuming that the problem is in the fuel injection system does anyone know how I might fix this? That is, is there any way to "clean" the fuel injection system?

Apologies for the length of this message--brevity is not my strong suit.

Your fuel injectors may be clogged and need to be cleaned / replaced.

That's what I'm thinking. After a bit of research I found that the best "non-removal" method is to use a high pressure fuel injector cleaning system. I found one on Amazon that includes a springlock connector adaptor to fit the Ford fuel rail. I ordered that plus a pint of Redline SI-1 fuel injector cleaner which seems to be the best one. And finally, I ordered a set of springlock connector removal tools...in case I ever need to work on my SRF's ac system.

The last thing I want to do is to have to remove the intake manifold and injectors.

I got a set of connector tools for my G2 and use them a lot on other cars.
You should be able to remove and replace the injectors without removing the intake, IIRC.
It is a matter of opinion whether you can clean the injectors by pushing cleaner through them. Some say they have to be taken apart to be properly cleaned. I think if they aren’t cleaned well, you have the risk of running lean in one or more cylinders and G2’s don’t like running lean.
The Mumm Bros have a good cleaning service.

I will look into removing them from the engine, and I will check w/the Mumm bros per your suggestion. Thank you!

It's been a while, but I've gotten new G2 injectors in the past from Marren fuel injection https://www.injector.com (cost about $400 for a new set in 2014). They appear to also offer a cleaning service. The part number for the injector "05SRF" and it looks like they're priced at $95 each. Injector service is around $30 per injector.
