My 1987 TII has been sitting for about three years. I just got it registered for the road in California about a week ago and I've been driving it on short runs. One of the last things I had done to the car before before putting the on nonop three yrs ago was putting in bigger fuel injectors. When the car is running you can smell raw fuel in the engine bay. I'm worried about an engine bay fire and was looking for a little advice on how to approach this problem.

If you can smell fuel then check for leaks.
there is a fuel pump check connector at the front passenger side of the car,near the headlight,AFM,etc.
it is a rubberized two wire connector.JUMP it when the car ignition is in ON position(NOT started).It will supply fuel to the rails and pressurize them so you can see if there is any leakage.

When checking your fuel rail, see if your fuel pressure dampner is leaking. If it is you'll need a new one or a banjo bolt mod. Arguments have been made over the banjo bolt but i've ran my car 3 years with no issues and no pulsation problems. I have a fuel pressure gauge on my a-pillar, 38 at idle 43 when gas pedal is pressed.

I had a similiar problem and found it to be leaky injectors..

This ^^^.

The fuel pulsation dampener is the usual culprit. Many 7's, from basically stock to seriously built, have had no issues running with the FPD deleted via the banjo bolt mod. Though some will contest its appropriateness, it's a great alternative to an expensive new unit from Mazda.

Just wanted to thank everyone for your help. I found the leak. It is the injector on the secondary rail on the firewall side which is leaking badly. I'm lucky I didn't have an engine bay fire driving on the freeway. In addition to the leaking injector I found a lot of broken connectors, missing clips and dry rotted injector seals so I have a lot of work to do. When I was checking for leaks I couldn't find the check connector for the fuel pump(I think my wiring harness has been messed with by someone else). I found another way to turn on the fuel pump. Take your filter off the Mass Air Flow meter and push in the air flap inside with the ignition on. This turns on the fuel pump.
