Question
Hi, I have a 87 K5 Blazer with a 5.7L engine and it won't start. With help from a friend I we found out it has a fuel problem. I have had the injectors tested, replaced the fuel filter, and with key on engine off you can listen to the fuel pump for 4 seconds. I am getting fuel to the TBI but I am not getting any spray from the injectors. what should I do?

Answer
Hi Jeff... check for voltage referance at the injectors... if you don't have inj pulse you will need to look at computer or the wiring to the inj from the computer... did you check ign module. make sure you have ign referance as well...hope this helps... merry christmas
