Recently purchased a 1987 V2500 Suburban with a 350 TBI. It has been nothing but trouble so far, but I'm not quite ready to give up on her.
I finally had it running really well after swapping/fixing lots of parts (battery, water pump, radiator, hoses, belts, spark plugs, knock sensor, map sensor, coolant temperature sensor) and fixing a vacuum leak. My mechanic recommended I replace the spark plug wires and make sure they are routed away from the exhaust manifold because there was still a slight misfire. While I was at it, I decided I might as well replace the cap and rotor.
Well, now it won't start. I'm getting spark at the plugs, and I've checked the order on the distributor cap about 10 times to make sure the firing order is right. I tried going back to the old cap and rotor to see if the new parts were faulty, but with no success. I think it has something to do with the timing but I'm not exactly sure where to go from here. Any ideas?
