L-jet problem

The problem is that your injectors have stuck. What you want to do is pull them out and individually apply 12 volts across them. You should here a audible click. Do not hold the 12V supply on continuously as you will over heat them and possibly burn them out. If this does not work them take all 4 injectors down to an injector specialist to get them cleaned and freed up. If you do get them freed up then it is a good idea to soak them in some sort of injector cleaner for a while as what causes them to stick is the fuel left in them has dried up leaving a varnish type substance.


What are the specs on your spyder. I have both a Fiat 124 sport(currently selling) and a Fiat 128 with a roof cut. I plan to buy a fiat 850 coupe and fit a suzuki G13B motor (1300-16 valve) into the back. I am looking at using a PC notebook style fuel injection system and do a little hoon car. At the very least it should be fun.
