I have a 97 Chevy 3500HD w/454 vortec I bought the truck not running and after checking it out found the pick up was bad replaced that and it started up but ran very rich After checking it out now I found the cylinder 1 fuel injector was running like a fuel pump all the time I replaced that and it seemed to be clearing up so I drove it around the block to clear it out only to get worse It coded p1435 so I pulled the distributor cap and found the rotor button mount was loose from the distributor so I replaced that now and no more code and it seemed to be running ok but after 2 minutes or so it started again to load up very bad and backfire I think the timing chain is ok but is there anyway to check witout pulling it apart?
