L-Jet

Driving home the other day, the car started to lose power after going over some very rough road and went another couple hundred yards before dying out. So I thought I may have had a bad injector but I was incorrect; although the pump was running it wouldn’t hold pressure. I could hear hissing from somewhere... Turned out to be filling #2 cyl with fuel

Long story short, a Noid light showed all 4 injectors open simultaneously. Pulling the harnesses off the injectors allowed for fuel pressure holding. It would appear that the ECU has crapped out.

I’ve read that they rarely fail, but maybe this one did.

Has anyone had a similar experience?

Thanks

maybe a bad head temp sensor?

Wouldn’t think so George, signal is open on all four, causing a fuel dump...

Could you have lost the ground on the top of the engine? I think that's where the injectors get grounded. The bumpy road means something came loose.

Hmmmm...

I’ll have a look Jerry, thanks.

Im with Jerry, D jet grounds ...... or that little braided ground
strap in the dizzy. All are instant stops. Go, No Go.

Or water in the plug or the ecu…sounds like all your injectors have gone to ground water will do that,had this issue with my 944 hydro-looked the engine,just saying ok.

several years ago, my '71 d-jet wasn't getting fuel. after trying all the usual stuff, i had it towed to a local well respected shop who also tried all the usual stuff before swapping in another customer's ecu...

they fail almost never...
