Dont give up on your truck bro... I know it can be frustrating when it seems like everything keeps breaking but just remember that the more you replace the less you have left to worry about later. You will figure it out. Just work your way through the basic checks like VLS said. Spark, fuel and so on.

Not trying to be rude or anything but you say your truck is 25 years old but your signiture says your jimmy is an 89. That is only 20 years old.... Are you talking about a different truck?

 

Send me back to school. It is an 89 and apparently I can not do simple math.

 

lol dont feel bad its still a long time to have a truck and a crap load of miles you put on that thing....lol obviously you have taken great car of her.

 

I know a lot about the 4.3L TBI but have no experience at all with a 4.3 CPI engine. Especially the fuel delivery system.

 

Well got the Ford F 150, hopefully it will do better for me than that blazer. Never had so many problems with a vehicle in my life. Still wish I could've picked up an older dodge. Still got the blazer, maybe one day i'll mess with it. Who knows!! Seems like a vehicle that would cost WAY more than what's it's worth to keep functional.

 

Best of luck with your new truck. If you decide to do more work on the Blazer, feel free to come back aboard and post up.

 

I will work on it. I just checked to see if it is getting spark and low and behold, it is. Now what could be the problem?? Gets gas, gets spark, what now?? I just want my blazer running again. Any suggestions???

 

I would check timing. If you have fuel and spark and the engine cranks with out starting I would suspect timing. I would start by loosening the hold down bolt and rotating the distributer a little each way to see if it will start. You could also verify time by bringing up the number one piston on the compression strok to TDC, then verify that the rotor is pointing towards the number one plug wire at the cap.

 

How do I bring the engine to TDC????

 

pull the #1 spark plug out,stuff a rag into the hole or hold your finger over the hole and have someone bump the engine around slowly until it blows the rag out,then look at the timing mark on the crank pulley,it should be close to the mark on the timing cover, if it isnt rotate the engine by hand to line it up, pull the dist cap off and make sure the rotor button is pointing at #1,,start with that and let us know.
