Hi I have 1990 Chevy s-10 with 195,000 miles on it and it is in great shape but the other day I was leaving work and she stopped running. I had this problem before and it was a fuel relay but this time that was not the fix. I am getting fuel so I think it may be a timing problem now. after I got it towed home I did get it running for a while as long as I held the gas pedal down when I left off it would stall. I changed the plugs,wires,distributor,cap and rotor,ignition modual (was on the new dist) new coil. Now it won't start at all I checked it while it was TDC and it looks like I did everything right. I am now thinking a timing chain?? Could this be the problem and is the anyway to know without removing the cover?? When I try to start it now it just turns over and over?
