changed distributor, plugs,wires,fuel filter,fuel pump,gas and still will not start PLEASE HELP 98 blazer 4.3

 

try rolling the motor to TDC and then pull the distributor cap and make sure that you have the thing in there right. when at TDC the rotor should be pointing that the plug wire that goes to cylinder one. if it isnt, pull the distributor and re-align everything.

 

What Twip said, mine wouldn't start until I did that. It took me a few tries though

 

Do you have spark?
Do you have proper fuel pressure at the test port?

 

There are TWO tdc. Unless its a two stroke. But yeah prolly got the dis ont tooth off.

 

does it try to start? lights work? explain what happens when you try to start, I mean could be starter or ignition switch issues??? check engine light come on? battery light come on?

 

Is the starter turning it over? Air filter not clogged? Do you have proper fuel pressure(55+)? Do you have spark? Is it in the right order and at the right time? Evidence of fuel spraying? If all these can be answered yes then it should run

 

I believe its TDC problem I will check also I have a parasitic battery drain soon as you turn the key it dies even if u jump the battery it dies
