01 Blazer Fuel Injection Spider

This Blazer has 110,000 miles and it died in traffic the other day. Now its not starting, but it tries.

I tested the fuel pump, replaced filter and have 50psi fuel pressure. When you try and start it, you get a strong smell from the tail pipe.

Is there a way to test this FI spider?

Just to add something, I did pull one plug and it was dry, but smelled strong of gas.

Re: 01 Blazer Fuel Injection Spider

Fuel pressue should be 60-66 psi.

Check for spark at all cylinders. Distributor caps are really common on these.

I replaced the spider and that solved the issue.

Re: 01 Blazer Fuel Injection Spider

I'm curious.... did you have the original style poppet injectors and replace them with the updated style? How hard was the job?
I have a 2000 blazer that I don't know what it has for injectors.
