The knock sensor will go to the lower hole, make sure you follow tightening instructions or it will no function correctly. Put a liquid sealant on threads, don't use tape.

Mar 28, 2011 - There are so many ways to test for a blown head gasket on your 4.3L, 5.0L, 5.7L GM van (or mini-van, pick up, SUV) that it can get confusing.

This darn little engine just keeps going. ... I have a 2003 chevy blazer and the oil cooler line from the oil filter to ... I have a 95 Chevy s10 v6 vortec 2wd that is slightly dripping oil out of agasket ... I'm having same problem 2001 Chevy Blazer 4x4 (not xtreme) not sure if those same bolts are missing on mine.
If there both 4.3's the interchange says the will fit but I have found that you need to look everything over well. I have found that some have knock sensors with different sizes (2 wire and 1 wire) and the oil pan and pump sometimes have to be swapped going from 2wd to a 4wd. Sit them side by side and check everything is my best advice.
what did you do (replace it) if you still have a miss you may need to tune it up / make sure the fuel pump you bought is for the right psi for your blazer
The color codes will be different so when you take the harness off the 95 make sure that you label ALL the connectors to make it easier to install it on your Blazer. You may also have to change some sensors or switches up to 95 so that the harness will fit. Label all the empty connectors with their location in the 95 because they will be for options that may or may not be on your Blazer. If you have to access a wire diagram to complete the job then use the 95. DON'T let someone else take the 95 harness out for you andtake a rough diagram of your truck with the plug-ins marked for location and # of pins for wires. Basically it should fit but attention to detail is a must.
Also check out faxonautoliterature. They list GM service manuals but also GM books for engine interchanges that may prove to be very helpful. Hope this helps.
A spider injector is located underneath the intake plenum and this is multi-port. Otherwise you have a throttle body injector system. Vortec engines have spider injectors and they are super expensive to replace ($400.00- 850.00) each ! There is only one spider injector for each engine it has 6 legs/fuel tubes that go to each cylinder.
swng,
1) Is the service engine soon light ever on when engine is running?
2) Per your description I would look at the ECT sending unit. It sends coolant temperature information the the Engine Control Module for proper fuel delivery for cold engine start. It may have lost its calibration.
Let me know.
Regards,
you need the firing order?? it is 1, 6, 5, 4, 3, 2 clockwise. Number
one on cap is forward position, or 6 o'clock position, just left of the
hold down bolt.
