Customer Question

i changed my spark plugs in my 2000 chevy s-10 blazer. i double checked the firing order and everything is okay. but when i try to start the blazer, it seems like it''s not getting anything. it''s just turning over again and again. prior to me changing the spark plugs and wires, the blazer was mis firing and a mechanic told me that i needed to change my plugs and wires. i have gotten a block test on it and it passed so im good there. what do i do? please help!!!

Hi,

Ok, first, look at diagram below and double checking the firing order:

If firing order is correct, next you need to check that connections at plugs and distributor and coil are tight. If they are secure, check for spark from coil to the distributor.
