This All started a month ago or more with a no start. Since then I'v replaced here we go cps,dist,icu,coil,timing chain,2 valves 1push rod lapped all valve and did guides and seals,compression tested all cylinders between 120&115 #3 is 95 I'm about to put in the ecu because after messing with the green and white wire I had a relay buzz and then nothing. Power is going to relays but nothing coming out in key on position. Not to mention new shocks tires u joints calipers hubs axle joints rotors and brakes huh pretty cool rig but now I need it to run real bad. And refreshed all grounds i.e. I have followed every thread I can find and took advise given there in. lol help

About how hard would it be to replace the blower on a 92 and how long would it take? Bearings or something are starting to fuss in mine, don't want it to fail when i start college since my classes are gonna be 20ish miles away from home.
