I just bought a 93 S10 Blazer with a 4.3 that was not running. Fuel pump was not coming on, so I installed a new fuel pump. Fuel pump is coming on now but Still wont start. I can start it by spraying gas into the cpi. What should I check next?

 

will the truck turn over???? check battery connections, make sure that you are getting spark at plugs.

 

Yes it will crank over.It willrun if you spray into cpi also.

 

have you tested the fuel pressure??? clogged injector?

 

My Dad took it to a friend on a dolly , put on computer found out the fuel injection spyder is bad . Thanks for the help.
