1981 fuel injection

Post by JJCAPE »

So for some reason my car will not start today.. I only use it once a week but i drove it a couple of days ago no problem...
plenty of battery power.. I'm asking because it seems like there's no gas getting to injectors ... I cant smell any ....
is there a quick fix i can try.. the car has always started for me.... I thought someone could give me a place to start ...

thanks

You didn't give us much to go on. I take it that the engine cranks fine but just doesn't start? An engine that turns over can basically have one of three problems: fuel, spark, and timing. If you think it's fuel, then pull a spark plug and see if it's wet (an indication that the problem is spark or timing). You could also try spraying some carb cleaner or even WD40 into the air box while someone cranks the engine and see if it sputters. If the engine tries to start then you can begin trying to troubleshoot your fuel system.

There's a great troubleshooting guide for the Bosch AFC fuel injection system out there. The systems on our Spiders are pretty reliable and simple to repair.

This link may be the troubleshooting guide Iglade was referring to

Otherwise Brad Artigue has a great guide on his site, but you might as well buy his book.

Just for giggles, Check those two ground wires on the intake plenum, at the two rear screws above the injectors. If one is broken, injectors get no fuel.
