Hi everyone,

Here is my scenario, My blazer will not start without using starting fluid (I know, bad idea). First - I replaced the spark plugs and wires, it would start up on second key turn but after maybe 2 weeks it went back to not starting at all. Next, I replaced the fuel pump and fuel filter, it would tstart again on second key turn, now its back to not starting at all again without the starting fluid. The weather has since changed also, it is very cold out. I also did smell some fuel in the vehicle one time while driving a few weeks ago, but that also went away. Obviously it is getting the spark, should I try changing the pressure regulator? Car has about 95,000 miles on it and no rust on it.

Thanks again.

 

U have a fuel pressure gauge to check ur fuel pressure? Might be leaking off.

 

That was the same issue on my frst blazer. Bad spider
