hi my 1985 chevy blazer with the fuel injected 2.8 cought on fire and melted the vac-lines and the distruter cap i replaced them but when i did some thing happend and it wont start

What do you have for fuel pressure and does it leak down really fast? Have you checked for spark at the spark plugs? Did you get the wires back in the cap in the right order? The fire may have damaged the ignition module in the distributor.
