I bought this car not running. It appears the owner has tried diagnosing it with a bunch of tune up items. The car will turn over and get spark it also gets fuel to the rail but will not fire up. The fuel gauge is pegged full for some reason as he had the sending unit plug disconnected. The car has sat for about 5 years any ideas? It will fire if fuel is sprayed into the throttlebody.

5 YEARS! Plugged injectors from rotten fuel would be my first guess! 5 year old fuel turns to sticky varnish inside the fuel lines. The screens in the injector inlets could be completely blocked!

Yeah I siphoned all the old gas out of the tank and the little bit I did get in my mouth tasted like watered down laquer thinner or varsol. It also smelled horrible.

You need to make sure that you CLEAN the entire fuel system. The varnish is NOT just in the injectors. It is very likely that there is varnish accumulated inside the lines, rails and in short; throughout the system. Even after you get new injectors and fill up with fresh fuel, that varnish will begin to break loose and can foul your new injectors. I have personally seen this happen, it is not pretty!

There is No sure fire way to get all the varnish out short of replacing everything. I have used a mixture of lacquer thinner and gasoline to dissolve the varnish inside the tank and lines. The trick is to dissolve the varnish AND hold it in solution until it can be burned through the engine or pumped out of the tank. An engine running on this gasoline, lacquer thinner and dissolved varnish STINKS to high heaven AND you run the risk of plugging the new injectors!

Another way would be to fill the tank with lacquer thinner/gasoline mixture, allow it to set for at least 24-48 hours and then use the fuel pump to pump the cleaner mixture through the lines and out the front, without burning it in the engine. You catch the mixture being pumped out in a bucket or other container, I think you will be surprised what the mess looks like that comes out of the tank. After cleaning you will need to prepare to replace the filter several times until you get all the crap out of the tank. That is one way to clean it without dis-assembly or complete replacement.

After you get the tank and lines cleaned out pretty well, then you put the new injectors in (clean the rails at that time), replace the fuel filter, fill the tank with fresh gas and a good fuel system cleaner and run the car as much as you can. I would run a PREMIUM fuel system cleaner AND Marvel Mystery Oil in several tanks of fuel before switching to straight gasoline. Also USE "STABIL" if you are going to let the car set for any length of time. Keep the tank FULL of fuel when parked, this reduces condensation and to some extent, varnish buildup.

Fuel Gauge sender is likely varnished and NOT conducting the signal to ground. My 85 El Camino sat for 5 years and the sender did the same thing. Gauge laid all the way over past full, after I filled it with fuel and it sat a couple of days, the gauge "magically" began to work. I did not do anything, it just healed itself!

Good Luck!
