I have a 97 Blazer with a Cranks but No start condition. It was hard starting for several weeks, then just wouldn't start.
We have replaced the fuel pump, fuel filter, relay is good. We have excellent pressure now but no spark. We replaced the battery, the plugs and wires, ignition coil, cap and rotor. We have checked all fuses and all are good. Although I do find it odd that with all the elec components on this engine there is only 1 fuse center in the truck. We have checked wires in ignition switch for power and all seem fine. Ignition module has power and ground. I still feel we r missing something. I have read so many posts in different forums and webpages that I have completely confused myself. Can anyone PLEASE shed some light on where I should go from here.
Hi DawnR, welcome to the forum! A few questions:
1. How many miles are on your Blazer?
2. Can you pull codes from the PCM?
3. What is the fuel pressure when the ignition is on?
